How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

How to Write a Dissertation Literature Review – Steps & Tips

Published by Anastasia Lois at August 12th, 2021 , Revised On October 17, 2023

From an academic standpoint, a dissertation literature review can be defined as a survey of the thesis, journal articles, books, and other academic resources on any given research title . This article provides comprehensive guidelines on how to write a dissertation literature review.

A literature review in a dissertation is of critical importance primarily because it provides insight into the key concepts, advancements, theories, and results of your research questions  or  research problem .

However, it is essential to note that; a first-class dissertation literature review focuses on summarizing the academic sources used for research and analysing, interpreting, and assessing them to determine the gaps and differences in opinions, judgments, themes, and developments.

A good literature review will further elaborate on existing knowledge concerning the research hypothesis or questions.

View dissertation literature review examples here.  

When do you Write a Dissertation Literature Review?

Depending on your university’s guidelines, you might be required to include a literature review in the theoretical framework or the introduction.

Or you could also be asked to develop a standalone literature review chapter that appears before  the methodology  and  the findings  chapters of the dissertation.

In either case, your primary aim will be to review the available literature and develop a link between your research and the existing literature on your chosen topic.

Sometimes, you might be designated a literature review as a separate assignment . Regardless of whether you need to write a literature review for your dissertation or as a standalone project, some general guidelines for conducting literature will remain unchanged.

Here are the steps you need to take to write the literature review for a dissertation if you cannot write the literature review.

Steps of Writing a Literature Review

1. gather, assess, and choose relevant literature.

The first seed to take when writing your dissertation or thesis is to choose a fascinating and manageable research topic . Once a topic has been selected, you can begin searching for relevant academic sources.

If you are  writing a literature review for your dissertation, one way to do this is to find academic sources relevant to your  research problem or questions.

Without fully understanding current knowledge in the chosen study area, giving the correct direction to your research aim and objectives will be hard.

On the other hand, you will be expected to guide your research by developing a central question if you are writing a literature review as an individual assignment.

A notable difference here compared to the dissertation literature review is that you must answer this central question without conducting primary research (questionnaires, surveys, interviews). You  will be expected to address the question using only the existing literature.

Use Keywords and References to Find Relevant Literature

Create a list of keywords that are relevant to the topic of research. Find journals, articles, and books using these keywords. Here are links to some recognised online academic libraries and databases;

• Inspec, (Computer science, engineering, physics, chemistry)
• EconLit, (Economics)
• Google Scholar
• Your university’s online research database

Finding relevant academic sources from “the reference list” of an article you have already found in a research database effectively discovers relevant studies.

Consider noting frequently appearing references as they are likely to be highly authentic and important publications even though they didn’t appear in the keyword search.

Journal articles or books that keep appearing with different keywords and phrases are the ones you should manually look out for.

The more times an article has been referenced, the more influential it is likely to be in any research field. Google Scholar lets users quickly determine how often a particular article has been referenced.

2. Weighing and Selecting Academic Sources

It won’t be possible for you to read every publication related to your topic. An excellent way to select academic sources for your dissertation literature review is to read the abstract , which will help you decide whether the source is supportive and relevant to your research hypothesis or research questions.

To help you select sources relevant to your study, here are some questions for you to consider before making the decision.

• What research questions has the author answered with their research work?
• What fundamental concepts have been defined by the author?
• Did the researcher use an innovative methodology or existing frameworks to define fundamental methods, models, and theories?
• What are the findings, conclusion, and recommendations in the source book or paper?
• What is the relevance between the existing literature and the academic sources you are evaluating?
• Does the source article challenge, confirm, or add to existing knowledge on the topic?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Any breakthrough studies and key theories relevant to your research topic should be recorded as you search for highly credible and authentic academic sources.

The method of your review of literature depends on your academic subject. If your research topic is in the sciences, you must find and review up-to-date academic sources.

On the other hand, you might look into old and historical literature and recent literature if your research topic is in the humanities field.

Recording Information and Referencing Sources

It is recommended that you start to write your literature review as you read articles, journals, and books. Take notes which can be later merged into the text of the literature review. Avoid plagiarism  and record all sources used along with references.

A good way of recording information is to analyse each source, summarise the key concepts or theories and compile a complete list of references in the form of an annotated bibliography.

This is a beneficial practice as it helps to remember the key points in each academic source and saves you valuable time as you start the literature review write-up.

3. Identify Key Themes and Patterns

The next step is to look for themes and patterns in the chosen sources that would enable you to establish similarities and differences between their  results and interpretations .

This exercise will help you to determine the  structure and argument for your literature review. Here are some questions that you can think of when reading and recording information;

• Are any gaps in the existing literature?
• What are the weaknesses of the current literature that should be addressed?
• Were you able to identify any landmark research work and theories that resulted in the topic’s change of direction?
• What are the similarities and disagreements between these sources? Were you able to identify any contradictions and conflicts?
• What trends and themes were you able to identify? Are there any results, methods, or theories that lost credibility over time?

4. Structure of Literature Review

There is no acclaimed  literature review structure , which means that you can choose from a range of approaches (thematic, chronological, methodological, and theoretical) when deciding on the structure of the literature review .

However, before you begin to  write the literature review , it is important to figure out the strategy that would work best for you. For long literature reviews, you might decide to use a combination of these strategies. For example, you could discuss each of the themes chronologically.

1: Theoretical

You can discuss various significant concepts, models, and theories in your literature review to form the basis of a theoretical framework . You could also combine a range of theoretical approaches to develop your theoretical framework or debate the significance of a particular theoretical framework.

2: Methodological

The methodological approach will require you to relate the findings of studies conducted in different research areas and use different research methods .

• You might discover that results from the quantitative research approach are not the same as qualitative research.
• You might split the selected academic sources based on their discipline – engineering, and sciences.

3: Thematic

You may also deploy a thematic approach, especially if you identified repeating key themes and patterns. If that is the case, you will be expected to put each aspect of the topic into different subsections within your literature review.

For example, if your research topic is “employment issues in the UK for international students,” you can divide the key themes into subsections; legal status, poor language skills, immigration policy, and economic turmoil.

4: Chronological

The most straightforward approach is to trace the development of the topic over time. However, if you choose this strategy, avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points, and critical debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

5. Writing your Literature Review 

Whether it’s a dissertation literature review or a standalone literature review assignment you have been assigned, you will be expected to divide your literature review into three larger sections – introduction, main body, and a conclusion.

What you write under these three segments will depend on the aim of your study.

Section 1 – Introduction

Here you will be required to state the objectives of the literature review clearly;

Introduction to Dissertation Literature Review Recapitulate your research problem or questions with a summary of the sources you reviewed when the literature review is for your thesis or dissertation. Consider highlighting gaps in existing knowledge and stress the suitability of your topic.

For example:

Research problem A has been debated in many recent studies.

While the topic has been explored concerning A, the B aspect has not yet been explored.

Individual Literature Review Project When reviewing literature for an individual literature review assignment, make sure that you clearly state the purpose of the research and debate the scope of the literature (how recent or old are the academic sources you are reviewing).

Section 2 – Main Body

As previously mentioned, you can divide this section into further subsections depending on your literature review’s length. You can also have a separate heading for each research method, theme, or theory to help your readers better understand your research.

Here are some tips for you to write a flawless main body of literature review;

• Summarize and Combine ; Highlight the main findings from each academic source and organise them into one whole piece without losing coherence.
• Evaluate and interpret; Make sure you are giving opinions and arguments of your own where possible. Simply rephrasing what others have said will undermine your work. You will be expected to debate and discuss other studies’ results about your research questions or aim.
• Analytical Evaluation; It is essential to unmistakably present the literature you have reviewed and the merits and weaknesses of the literature.
• Make Use of  Topic Sentences and Transitions; in organized subsections within the literature review to establish conflicts, differences, similarities, and relationships.

Example of How to Write a Dissertation Literature Review

The below example belongs to the body of a literature review on the effectiveness of e-recruitment in small and medium-sized enterprises in the United Kingdom’s IT sector.

E-recruitment means explicitly using digital technologies to recruit, select, and orient employees. The benefits of e-recruitment in the literature have been studied: increased access to a pool of candidates, time and cost savings, and greater flexibility for the organisation.

In contrast, the literature states that e-recruitment might not properly achieve the goal of retaining the workforce with the required skills to participate in the work environment (Lad & Das, 2016). Also, e-recruitment might be based on a flawed website design or poor application process, which might deter potential employees (Anand & Devi, 2016) .

This section of the study will focus on the existing studies linked to the effectiveness of e-recruitment. Human resource management is an essential function of business organisations because it manages the workforce.

The goal of HR should be to develop a strategic approach in which the organisation’s strategic goals can be attained efficiently and effectively. The advent of digital technologies has helped transform human resource management’s nature concerning recruiting and selecting employees for organisations.

The Internet’s benefits have reduced search time for candidates and significant cost savings for organisations. Finally, it offers a transparent method for obtaining information about specific candidates. E-recruitment helps organisations hire people from any part of the world as it promotes opportunities and benefits the organisation efficiently.

Sharma (2014) argues that 75% of human resource professionals in developed countries are now using e-recruitment to hire employees for their organisations. Additionally, some 2 out of 4 job seekers will use the Internet to source job opportunities.

Another evidence to support the rise of e-recruitment is a study by Holm (2014), which found that all Fortune 100 companies will be using some form of e-recruitment to advertise vacant positions.

The implications are that e-recruitment is a popular strategy for various positions, from blue-collar roles to white-collar and professional positions. The benefits of e-recruitment have been identified in the literature. Girard & Fallery (2009) argues that e-recruitment helps to save time for organisations and employees.

Employers can use several methods to post jobs in as little as 20 minutes. There are no limits to ad size, and they can receive resumes immediately. In contrast, the traditional methods require some time to appear, for example, in a newspaper, and might be there for a limited period.

Section 3 – Conclusion

When writing the dissertation literature review conclusion, you should always include a summary of the key findings which emerged from the literature and their relevance and significance to your research objectives.

Literature Review for Dissertation

If you are writing a dissertation literature review, you will be required to demonstrate how your research helped to fill an evident gap in research and contributed to the current knowledge in the field. Similarly, you can explain how you used the existing patterns, themes, and theories to develop your research framework.

Literature Review as an Individual Assignment

You can summarize your review of your literature’s significance and implications and provide recommendations for future work based on the gaps in existing knowledge you acknowledged.

6. Proofread

Finally, thoroughly proofread your literature review for grammatical, structural, spelling, and factual errors before submitting it to your university.

If you are unable to proofread and edit your paper, then you could take advantage of our  editing and proofreading service , which is designed to ensure that your completed literature review satisfies each of your module or project’s requirements. We have Masters and PhD qualified writers in all academic subjects, so you can be confident that they will edit and improve the quality of your to 2:1 or First Class standard, as required.

Valuable Tips for Writing Dissertation Literature Review

Your literature review must systematically comply with your research area. Underneath, we are stating some essential guidelines for a compact literature review.

Contribute to the Literature

After carefully reviewing the literature, search for the gaps in knowledge and state how you have analysed the literature with a different perspective and contributed to your research area.

Keep your Argument Systematic & Consistent

Your arguments must be consistent and systematic while discussing theories and controversial and debatable content. Be logical in your review and avoid vague statements, not to make it complex for the readers.

Provide Adequate References

Don’t forget to provide references, as they are the soul of the dissertation. While discussing different aspects of the research, provide a reasonable number of references, as your discussion and interpretations must be backed up by relevant evidence. You can see an example provided in the sample paragraph above.

Be Precise While Writing a Review

You aren’t required to write every inch of information you have studied while reviewing the literature. You will be able to find tons of information that will correlate with your research area.

Be precise while writing the review, as writing unnecessary, irrelevant information won’t give a good impression. State the most reliable sources in your review without jumping into every possible source.

Don’t go Excessively for Direct Quotes

Direct quoting is required to make a point more impactful, but you should opt for it to a specific limit. Making excessive use of it won’t be a good idea.

The direct quote is mainly used when you think that the words being used by the actual author are so authentic in their meaning that you can’t replace or rephrase them. Try to avoid relying too much on a single author/s work.

Discussing their contributions and keeping the review going briefly would be better. While mentioning the points discussed by the prior researchers – link your arguments with their discussion. Don’t write the crux of their discussion, yet tell if your argument goes along with them.

Express your Analysis

The literature review is written to summarize your perspective, which should be backed up in light of the literature. Critically analyze literature with a rational approach and express your opinion on it.

Use the Correct Referencing Style

While referencing, one must use proper referencing styles, i.e., Harvard reference style, etc. Different referencing styles are used for in-text citations, while different for end-text citations.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed   Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

Overview of writing the literature review

Conducting a literature review enables you to demonstrate your understanding and knowledge of the existing work within your field of research. Doing so allows you to identify any underdeveloped areas or unexplored issues within a specific debate, dialogue or field of study. This, in turn, helps you to clearly and persuasively demonstrate how your own research will address one or more of these gaps.

Disciplinary differences

Please note: this guide is not specific to any one discipline. The literature review can vary depending on the nature of the research and the expectations of the school or department. Please adapt the following advice to meet the demands of your dissertation and the expectations of your school or department. Consult your supervisor for further guidance; you can also check out  Writing Across Subjects guide .

Guide contents

As part of the Writing the Dissertation series, this guide covers the most common expectations for the literature review chapter, giving you the necessary knowledge, tips and guidance needed to impress your markers!  The sections are organised as follows:

• Getting Started  - Defines the literature review and presents a table to help you plan.
• Process -  Explores choosing a topic, searching for sources and evaluating what you find.
• Structure  - Presents key principles to consider in terms of structure, with examples to illustrate the concepts.
• Research gap - Clarifies what is meant by 'gap' and gives examples of common types of gaps.
• What to Avoid  - Covers a few frequent mistakes you'll want to...avoid!

What is the literature review?

The literature review of a dissertation gives a clear, critical overview of a specific area of research. Our main Writing the Dissertation - Overview and Planning guide explains how you can refine your dissertation topic  and begin your initial research; the next tab of this guide, 'Process', expands on those ideas. In summary, the process of conducting a literature review usually involves the following:

• Conducting a series of strategic searches to identify the key texts within that topic.
• Identifying the main argument in each source, the relevant themes and issues presented and how they relate to each other.
• Critically evaluating your chosen sources and determining their strengths, weaknesses, relevance and value to your research along with their overall contribution to the broader research field.
• Identifying any gaps or flaws in the literature which your research can address.

Literature review as both process and product

Writers should keep in mind that the phrase 'literature review' refers to two related, but distinct, things:

• 'Literature review' refers, first, to the  active process  of discovering and assessing relevant literature.
• 'Literature review' refers, second, to the  written product  that emerges from the above process.

This distinction is vital to note because  every  dissertation requires the writer to engage with and consider existing literature (i.e., to undertake the active  process ). Research doesn't exist in a void, and it's crucial to consider how our work builds from or develops existing foundations of thought or discovery. Thus, even if your discipline doesn't require you to include a chapter titled 'Literature Review' in your submitted dissertation, you should expect to engage with the process of reviewing literature.

Why is it important to be aware of existing literature?

• You are expected to explain how your research fits in with other research in your field and, perhaps, within the wider academic community.
• You will be expected to contribute something new, or slightly different, so you need to know what has already been done.
• Assessing the existing literature on your topic helps you to identify any gaps or flaws within the research field. This, in turn, helps to stimulate new ideas, such as addressing any gaps in knowledge, or reinforcing an existing theory or argument through new and focused research.

Not all literature reviews are the same. For example, in many subject areas, you are expected to include the literature review as its own chapter in your dissertation. However, in other subjects, the dissertation structure doesn't include a dedicated literature review chapter; any literature the writer has reviewed is instead incorporated in other relevant sections such as the introduction, methodology or discussion.

For this reason, there are a number of questions you should discuss with your supervisor before starting your literature review. These questions are also great to discuss with peers in your degree programme. These are outlined in the table below (see the Word document for a copy you can save and edit):

• Dissertation literature review planning table

Literature review: the process

Conducting a literature review requires you to stay organised and bring a systematic approach to your thinking and reading. Scroll to continue reading, or click a link below to jump immediately to that section:

Choosing a topic

The first step of any research project is to select an interesting topic. From here, the research phase for your literature review helps to narrow down your focus to a particular strand of research and to a specific research question. This process of narrowing and refining your research topic is particularly important because it helps you to maintain your focus and manage your material without becoming overwhelmed by sources and ideas.

Try to choose something that hasn’t been researched to death. This way, you stand a better chance of making a novel contribution to the research field.

Conversely, you should avoid undertaking an area of research where little to no work has been done. There are two reasons for this:

• Firstly, there may be a good reason for the lack of research on a topic (e.g. is the research useful or worthwhile pursuing?).
• Secondly, some research projects, particularly practice-based ones involving primary research, can be too ambitious in terms of their scope and the availability of resources. Aim to contribute to a topic, not invent one!

Searching for sources

Researching and writing a literature review is partly about demonstrating your independent research skills. Your supervisor may have some tips relating to your discipline and research topic, but you should be proactive in finding a range of relevant sources. There are various ways of tracking down the literature relevant to your project, as outlined below.

Make use of Library Search

One thing you don’t want to do is simply type your topic into Google and see what comes up. Instead, use Library Search to search the Library’s catalogue of books, media and articles.

Online training for 'Using databases' and 'Finding information' can be found here . You can also use the Library's subject pages to discover databases and resources specific to your academic discipline.

Engage with others working in your area

As well as making use of library resources, it can be helpful to discuss your work with students or academics working in similar areas. Think about attending relevant conferences and/or workshops which can help to stimulate ideas and allows you to keep track of the most current trends in your research field.

Look at the literature your sources reference

Finding relevant literature can, at times, be a long and slightly frustrating experience. However, one good source can often make all the difference. When you find a good source that is both relevant and valuable to your research, look at the material it cites throughout and follow up any sources that are useful. Also check if your source has been cited in any more recent publications.

Think of the bibliography/references page of a good source as a series of breadcrumbs that you can follow to find even more great material.

Evaluating sources

It is very important to be selective when choosing the final sources to include in your literature review. Below are some of the key questions to ask yourself:

• If a source is tangentially interesting but hasn’t made any particular contribution to your topic, it probably shouldn’t be included in your literature review. You need to be able to demonstrate how it fits in with the other sources under consideration, and how it has helped shape the current state of the literature.
• There might be a wealth of material available on your chosen subject, but you need to make sure that the sources you use are appropriate for your assignment. The safest approach to take is to use only academic work from respected publishers. However, on occasions, you might need to deviate from traditional academic literature in order to find the information you need. In many cases, the problem is not so much the sources you use, but how you use them. Where relevant, information from newspapers, websites and even blogs are often acceptable, but you should be careful how you use that information. Do not necessarily take any information as factual. Instead be critical and interpret the material in the context of your research. Consider who the writer is and how this might influence the authority and reliability of the information presented. Consult your supervisor for more specific guidance relating to your research.
• The mere fact that something has been published does not automatically guarantee its quality, even if it comes from a reputable publisher. You will need to critique the content of the source. Has the author been thorough and consistent in their methodology? Do they present their thesis coherently? Most importantly, have they made a genuine contribution to the topic?

Keeping track of your sources

Once you have selected a source to use in your literature review, it is useful to make notes on all of its key features, including where it comes from, what it says, and what its main strengths and weaknesses are. This way you can easily re-familiarise yourself with a source without having to re-read it. Keeping an annotated bibliography or completing source evaluation tables are a couple ways to do this.

Digital notebooks such as OneNote are another great option. You can keep all your notes and evaluation in one place, organising according to either subtopics/themes or sources. Customise the sections and pages of your notebook so it is easy to navigate and feels intuitive to how you think and process information. The video below will help you get started.

Writing your literature review

As we explored in the 'Getting Started' tab, the literature review is both a process you follow and (in most cases) a written chapter you produce. Thus, having engaged the review process, you now need to do the writing itself. Please continue reading, or click a heading below to jump immediately to that section.

Guiding principles

The structure of the final piece will depend on the discipline within which you are working as well as the nature of your particular research project. However, here are a few general pieces of advice for writing a successful literature review:

• Show the connections between your sources. Remember that your review should be more than merely a list of sources with brief descriptions under each one. You are constructing a narrative. Show clearly how each text has contributed to the current state of the literature, drawing connections between them.
• Engage critically with your sources. This means not simply describing what they say. You should be evaluating their content: do they make sound arguments? Are there any flaws in the methodology? Are there any relevant themes or issues they have failed to address? You can also compare their relative strengths and weaknesses.
• Signpost throughout to ensure your reader can follow your narrative.  Keep relating the discussion back to your specific research topic.
• Make a clear argument. Keep in mind that this is a chance to present your take on a topic. Your literature review showcases your own informed interpretation of a specific area of research. If you have followed the advice given in this guide you will have been careful and selective in choosing your sources. You are in control of how you present them to your reader.

There are several different ways to structure the literature review chapter of your dissertation. Two of the most common strategies are thematic structure and chronological structure (the two of which can also be combined ). However you structure the literature review, this section of the dissertation normally culminates in identifying the research gap.

Thematic structure

Variations of this structure are followed in most literature reviews. In a thematic structure , you organise the literature into groupings by theme (i.e., subtopic or focus). You then arrange the groupings in the most logical order, starting with the broadest (or most general) and moving to the narrowest (or most specific).

The funnel or inverted pyramid

To plan a thematic structure structure, it helps to imagine your themes moving down a funnel or inverted pyramid  from broad to narrow. Consider the example depicted below, which responds to this research question:

What role did the iron rivets play in the sinking of the Titanic?

The topic of maritime disasters is the broadest theme, so it sits at the broad top of the funnel. The writer can establish some context about maritime disasters, generally, before narrowing to the Titanic, specifically. Next, the writer can narrow the discussion of the Titanic to the ship's structural integrity, specifically. Finally, the writer can narrow the discussion of structural integrity to the iron rivets, specifically. And voila: there's the research gap!

The broad-to-narrow structure is intuitive for readers. Thus, it is crucial to consider how your themes 'nest inside' one another, from the broad to the narrow. Picturing your themes as nesting dolls is another way to envision this literature review structure, as you can see in the image below.

As with the funnel, remember that the first layer (or in this case, doll) is largest because it represents the broadest theme. In terms of word count and depth, the tinier dolls will warrant more attention because they are most closely related to the research gap or question(s).

The multi-funnel variation

The example above demonstrates a research project for which one major heading might suffice, in terms of outlining the literature review. However, the themes you identify for your dissertation might not relate to one another in such a linear fashion. If this is the case, you can adapt the funnel approach to match the number of major subheadings you will need.

In the three slides below, for example, a structure is depicted for a project that investigates this (fictional) dissertation research question: does gender influence the efficacy of teacher-led vs. family-led learning interventions for children with ADHD? Rather than nesting all the subtopics or themes in a direct line, the themes fall into three major headings.

The first major heading explores ADHD from clinical and diagnostic perspectives, narrowing ultimately to gender:

• 1.1 ADHD intro
• 1.2 ADHD definitions
• 1.3 ADHD diagnostic criteria
• 1.4 ADHD gender differences

The second major heading explores ADHD within the classroom environment, narrowing to intervention types:

• 2.1 ADHD in educational contexts
• 2.2 Learning interventions for ADHD
• 2.2.1 Teacher-led interventions
• 2.2.2 Family-led interventions

The final major heading articulates the research gap (gender differences in efficacy of teacher-led vs. family-led interventions for ADHD) by connecting the narrowest themes of the prior two sections.

Multi-funnel literature review structure by Academic Skills Service

To create a solid thematic structure in a literature review, the key is thinking carefully and critically about your groupings of literature and how they relate to one another. In some cases, your themes will fit in a single funnel. In other cases, it will make sense to group your broad-to-narrow themes under several major headings, and then arrange those major headings in the most logical order.

Chronological structure

Some literature reviews will follow a  chronological structure . As the name suggests, a review structured chronologically will arrange sources according to their publication dates, from earliest to most recent.

This approach can work well when your priority is to demonstrate how the research field has evolved over time. For example, a chronological arrangement of articles about artificial intelligence (AI) would allow the writer to highlight how breakthroughs in AI have built upon one another in sequential order.

A chronological structure can also suit literature reviews that need to capture how perceptions or understandings have developed across a period of time (including to the present day). For example, if your dissertation involves the public perception of marijuana in the UK, it  could  make sense to arrange that discussion chronologically to demonstrate key turning points and changes of majority thought.

The chronological structure can work well in some situations, such as those described above. That being said, a purely chronological structure should be considered with caution.  Organising sources according to date alone runs the risk of creating a fragmented reading experience. It can be more difficult in a chronological structure to properly synthesize the literature. For these reasons, the chronological approach is often blended into a thematic structure, as you will read more about, below.

Combined structures

The structures of literature reviews can vary drastically, and for any given dissertation there will be many valid ways to arrange the literature.

For example, many literature reviews will  combine  the thematic and chronological approaches in different ways. A writer might match their major headings to themes or subtopics, but then arrange literature chronologically within the major themes identified. Another writer might base their major headings on chronology, but then assign thematic subheadings to each of those major headings.

When considering your options, try to imagine your reader or audience. What 'flow' will allow them to best follow the discussion you are crafting? When you are reading articles, what structural approaches do you appreciate in terms of ease and clarity?

Identifying the gap

The bulk of your literature review will explore relevant points of development and scholarly thought in your research field: in other words, 'Here is what has been done so far, thus here is where the conversation now stands'. In that way, you position your project within a wider academic discussion.

Having established that context, the literature review generally culminates in an articulation of what remains to be done: the  research gap  your project addresses. See the next tab for further explanation and examples.

Demystifying the research gap

The term research gap   is intimidating for many students, who might mistakenly believe that every single element of their research needs to be brand new and fully innovative. This isn't the case!

The gap in many projects will be rather niche or specific. You might be helping to update or re-test knowledge rather than starting from scratch. Perhaps you have repeated a study but changed one variable. Maybe you are considering a much discussed research question, but with a lesser used methodological approach.

To demonstrate the wide variety of gaps a project could address, consider the examples below. The categories used and examples included are by no means comprehensive, but they should be helpful if you are struggling to articulate the gap your literature review has identified.

***P lease note that the content of the example statements has been invented for the sake of demonstration. The example statements should not be taken as expressions of factual information.

Gaps related to population or geography

Many dissertation research questions involve the study of a specific population. Those populations can be defined by nationality, ethnicity, gender, sexuality, socioeconomic class, political beliefs, religion, health status, or other factors. Other research questions target a specific geography (e.g. a country, territory, city, or similar). Perhaps your broader research question has been pursued by many prior scholars, but few (or no) scholars have studied the question in relation to your focal population or locale: if so, that's a gap.

• Example 1:  As established above, the correlations between [ socioeconomic status ] and sustainable fashion purchases have been widely researched. However, few studies have investigated the potential relationship between [ sexual identity ] and attitudes toward sustainable fashion. Therefore...
• Example 2:  Whilst the existing literature has established a clear link between [ political beliefs ] and perceptions of socialized healthcare, the influence of [ religious belief ] is less understood, particularly in regards to [ Religion ABC ].
• Example 3:  Available evidence confirms that the widespread adoption of Technology XYZ in [ North America ] has improved manufacturing efficiency and reduced costs in the automotive sector. Using predictive AI models, the present research seeks to explore whether deployment of Technology XYZ could benefit the automotive sector of [ Europe ] in similar ways.

Gaps related to theoretical framework

The original contribution might involve examining something through a new lens.  Theoretical framework  refers, most simply, to the theory or theories a writer will use to make sense of and shape (i.e., frame ) their discussion. Perhaps your topic has been analysed in great detail through certain theoretical lenses, but you intend to frame your analysis using a theory that fewer scholars have applied to the topic: if so, that's a gap.

• Example 1:  Existing discussions of the ongoing revolution in Country XYZ frame the unrest in terms of [ theory A ] and [ theory B ]. The present research will instead analyse the situation using [ theory C ], allowing greater insight into...
• Example 2:  In the first section of this literature review, I examined the [ postmodern ], [ Marxist ], and [ pragmatist ] analyses that dominate academic discussion of The World According to Garp.  By revisiting this modern classic through the lens of [ queer theory ], I intend to...

Gaps related to methodological approach

The research gap might be defined by differences of methodology (see our Writing the Methodology guide for more). Perhaps your dissertation poses a central question that other scholars have researched, but they have applied different methods to find the answer(s): if so, that's a gap.

• Example 1:  Previous studies have relied largely upon the [ qualitative analysis of interview transcripts ] to measure the marketing efficacy of body-positive advertising campaigns. It is problematic that little quantitative data underpins present findings in this area. Therefore, I will address this research gap by [ using algorithm XYZ to quantify and analyse social-media interactions ] to determine whether...
• Example 2: Via [ quantitative and mixed-methods studies ], previous literature has explored how demographic differences influence the probability of a successful match on Dating App XYZ. By instead [ conducting a content analysis of pre-match text interactions ] on Dating App XYZ, I will...

Scarcity as a gap

Absolutes such as never  and always  rarely apply in academia, but here is an exception: in academia, a single study or analysis is  never  enough. Thus, the gap you address needn't be a literal void in the discussion. The gap could instead have to do with  replicability  or  depth/scope.  In these cases, you are adding value and contributing to the academic process by testing emerging knowledge or expanding underdeveloped discussions.

• Example:  Initial research points to the efficacy of Learning Strategy ABC in helping children with dyslexia build their reading confidence. However, as detailed earlier in this review, only four published studies have tested the intervention, and two of those studies were conducted in a laboratory. To expand our growing understanding of how Learning Strategy ABC functions in classroom environments, I will...

Elapsed time as a gap

Academia values up-to-date knowledge and findings, so another valid type of gap relates to elapsed time. Many factors that can influence or shape research findings are ever evolving: technology, popular culture, and political climates, to name just a few. Due to such changes, it's important for scholars in most fields to continually update findings. Perhaps your dissertation adds value by contributing to this process.

For example, imagine if a scholar today were to rely on a handbook of marketing principles published in 1998. As good as that research might have been in 1998, technology (namely, the internet) has advanced drastically since then. The handbook's discussion of online marketing strategies will be laughably outdated when compared to more recent literature.

• Example:  A wide array of literature has explored the ways in which perceptions of gender influence professional recruitment practices in the UK. The bulk of said literature, however, was published prior to the #MeToo movement and resultant shifts in discourse around gender, power imbalances and professional advancement. Therefore...

What to avoid

This portion of the guide will cover some common missteps you should try to avoid in writing your literature review. Scroll to continue reading, or click a heading below to jump immediately to that section.

Writing up before you have read up

Trying to write your literature review before you have conducted adequate research is a recipe for panic and frustration. The literature review, more than any other chapter in your dissertation, depends upon your critical understanding of a range of relevant literature. If you have only dipped your toe into the pool of literature (rather than diving in!), you will naturally struggle to develop this section of the writing. Focus on developing your relevant bases of knowledge before you commit too much time to drafting.

Believing you need to read everything

As established above, a literature review does require a significant amount of reading. However, you aren't expected to review  everything ever written  about your topic. Instead, aim to develop a more strategic approach to your research. A strategic approach to research looks different from one project to the next, but here are some questions to help you prioritise:

• If your field values up-to-date research and discoveries, carefully consider the 'how' and 'what' before investing time reading older sources: how will the source function in your dissertation, and what will it add to your writing?
• Try to break your research question(s) down into component parts. Then, map out where your literature review will need to provide extensive detail and where it can instead present quicker background. Allocate your research time and effort accordingly. 

Omitting dissenting views or findings

While reviewing the literature, you might discover authors who disagree with your central argument or whose own findings contradict your hypothesis. Don't omit those sources: embrace them! Remember, the literature review aims to explore the academic dialogue around your topic: disagreements or conflicting findings are often part of that dialogue, and including them in your writing will create a sense of rich, critical engagement. In fact, highlighting any disagreements amongst scholars is a great way to emphasise the relevance of, and need for, your own research.

Miscalculating the scope

As shown in the funnel structure (see 'Structure' tab for more), a literature review often starts broadly and then narrows the dialogue as it progresses, ultimately bringing the reader to the dissertation's specific research topic (e.g. the funnel's narrowest point).

Within that structure, it's common for writers to miscalculate the scope required. They might open the literature review far too broadly, dedicating disproportionate space to developing background information or general theory; alternately, they might rush into the narrowest part of the discussion, failing to develop any sense of surrounding context or background, first.

It takes trial and error to determine the appropriate scope for your literature review. To help with this...

• Imagine your literature review subtopics cascading down a stairwell,  as in the illustration below.
• Place the broadest concepts on the highest steps, then narrow down to the most specific concepts on the lowest steps: the scope 'zooms in' as you move down the stairwell.
• Now, consider which step is the most logical starting place for your readers. Do they need to start all the way at the top, or should you 'zoom in'?

The illustration above shows a stairwell diagram of a dissertation that aims to analyse Stephen King's horror novel  The Stand  through the lens of a specific feminist literary theory.

• If the literature review began on one of the bottom two steps, this would feel rushed and inadequate. The writer needs to explore and define the relevant theoretical lens before they discuss how it has been applied by other scholars.
• If the literature review began on the very top step, this would feel comically broad in terms of scope: in this writing context, the reader doesn't require a detailed account of the entire history of feminism!

The third step, therefore, represents a promising starting point: not too narrow, not too broad.

The 'islands' structure

Above all else, a literature review needs to synthesize a range of sources   in a logical fashion. In this context, to  synthesize  means to bring together, connect, weave, and/or relate. A common mistake writers make is failing to conduct such synthesis, and instead discussing each source in isolation. This leads to a disconnected structure, with each source treated like its own little 'island'. The island approach works for very few projects.

Some writers end up with this island structure because they confuse the nature of the  literature review  with the nature of an annotated bibliography . The latter is a tool you can use to analyse and keep track of individual sources, and most annotated bibliographies will indeed be arranged in a source-by-source structure. That's fine for pre-writing and notetaking, but to structure the literature review, you need to think about connections and overlaps between sources rather than considering them as stand-alone works.

If you are struggling to forge connections between your sources, break down the process into tiny steps:

• e.g. Air pollution from wood-burning stoves in homes.
• e.g.  Bryant and Dao (2022) found that X% of small particle pollution in the United Kingdom can be attributed to the use of wood-burning stoves.
• e.g.  A study by Williams (2023) reinforced those findings, indicating that small particle pollution has...
• e.g.  However, Landers (2023) cautions that factor ABC and factor XYZ may contribute equally to poor air quality, suggesting that further research...

The above exercise is  not  meant to suggest that you can only write one sentence per source: you can write more than that, of course! The exercise is simply designed to help you start synthesizing the literature rather than giving each source the island treatment.

Q: I still don't get it - what's the point of a literature review?

A: Let's boil it down to three key points...

• The literature review provides a platform for you, as a scholar, to demonstrate your understanding of how your research area has evolved. By engaging with seminal texts or the most up-to-date findings in your field, you can situate your own research within the relevant academic context(s) or conversation(s).
• The literature review allows you to identify the research gap your project addresses: in other words, what you will add to discussions in your academic field.
• Finally, the literature review justifies the reason for your research. By exploring existing literature, you can highlight the relevance and purpose of your own research.

Q: What if I don't have a gap?

A:  It's normal to struggle with identifying a research gap. This can be particularly true if you are working in a highly saturated research area, broadly speaking: for example, if you are studying the links between nutrition and diabetes, or if you are studying Shakespeare.

The 'What to Avoid' tab explained that  miscalculating the scope  is a common mistake in literature reviews. If you are struggling to identify your gap, scope might be the culprit, particularly if you are working in a saturated field. Remember that the gap is the narrowest part of the funnel, the smallest nesting doll, the lowest step: this means your contribution in that giant academic conversation will need to be quite 'zoomed in':

This is not a valid gap →  Analysing Shakespeare's sonnets.

This might be a valid gap →  Conducting an ecocritical analysis of the visual motifs of Shakespeare's final five procreation sonnets (e.g. sonnets number thirteen to seventeen).

In the above example, the revised attempt to articulate a gap 'zooms in' by identifying a particular theoretical lens (e.g. ecocriticism), a specific convention to analyse (e.g. use of visual motifs), and a narrower object (e.g. five sonnets rather than all 150+). The field of Shakespeare studies might be crowded, but there is nonetheless room to make an original contribution.

Conversely, it might be difficult to identify the gap if you are working not in a saturated field, but in a brand new or niche research area. How can you situate your work within a relevant academic conversation if it seems like the 'conversation' is just you talking to yourself?

In these cases, rather than 'zooming in', you might find it helpful to 'zoom out'. If your topic is niche, think creatively about who will be interested in your results. Who would benefit from understanding your findings? Who could potentially apply them or build upon them? Thinking of this in interdisciplinary terms is helpful for some projects.

Tip:  Venn diagrams and mind maps are great ways to explore how  your research connects to, and diverges from, the existing literature.

Q: How many references should I use in my literature review?

A:  This question is risky to answer because the variations between individual projects and disciplines make it impossible to provide a universal answer. The fact is that one dissertation might have 50 more references than another, yet the two projects could be equally rigorous and successful in fulfilling their research aims.

With that warning in mind, let's consider a 'standard' dissertation of around 10K words. In that context, referencing 30 to 40 sources in your literature review tends to work well. Again, this is  not  a universally accurate rule, but a ballpark figure for you to contemplate. If the 30 to 40 estimate seems frighteningly high to you, do remember that many sources will be used sparingly rather than being mulled over at length. Consider this example:

In British GP practices, pharmaceutical treatment is most often prescribed for Health Condition XYZ ( Carlos, 2019; Jones, 2020 ; Li, 2022 ). Lifestyle modifications, such as physical exercise or meditation practices, have only recently...

When writing critically, it's important to validate findings across studies rather than trusting only one source. Therefore, this writer has cited three recent studies that agree about the claim being made. The writer will delve into other sources at more length, but here, it makes sense to cite the literature and move quickly along.

As you search the databases and start following the relevant trails of 'research bread crumbs', you will be surprised how quickly your reference list grows.

Q: What if there isn't enough relevant literature on my topic?

A: Think creatively about the literature you are using and engaging with. A good start is panning out to consider your topic more broadly: you might not identify articles that discuss your  exact  topic, but what can you discover if you shift your focus up one level?

Imagine, for example, that Norah is researching how artificial intelligence (AI) can be used to provide dance instruction. She discovers that no one has written about this topic. Rather than panicking, she breaks down her research question into its component parts to consider what research  might  exist.

• First, dance instruction: literature on how dance has traditionally been taught (i.e., not with AI) is still relevant because it will provide background and context. To appreciate the challenges or opportunities that transition to AI instruction might bring, we need to understand the status quo. Norah might also search for articles that analyse how other technological shifts have affected dance instruction: for example, how YouTube popularized at-home dance study, or how live video services like Zoom enabled real-time interaction between dance pupils and teachers despite physical distance.
• Next, artificial intelligence used for instruction: Norah can seek out research on, and examples of, the application of AI for instructive purposes. Even if those purposes don't involve dance, such literature can contribute to illustrating the broader context around Norah's project.
• Could it be relevant to discuss the technologies used to track an actor's real-life movements and convert them into the motions of a video game character? Perhaps there are parallels!
• Could it be relevant to explore research on applications of AI in creative writing and visual art? Could be relevant since dance is also a creative field!

In summary, don't panic if you can't find research on your  exact  question or topic. Think through the broader context and parallel ideas, and you will soon find what you need.

Q: What if my discipline doesn't require a literature review chapter?

A: This is a great question. Whilst many disciplines dictate that your dissertation should include a chapter called Literature Review , not all subjects follow this convention. Those subjects will still expect you to incorporate a range of external literature, but you will nest the sources under different headings.

For example, some disciplines dictate an introductory chapter that is longer than average, and you essentially nest a miniature literature review inside the introduction, itself. Although the writing is more condensed and falls under a subheading of the introduction, the techniques and principles of writing a literature review (for example, moving from the broad to the narrow) will still prove relevant.

Some disciplines include chapters with names like Background , History , Theoretical Framework , etc. The exact functions of such chapters differ, but they have this in common: reviewing literature. You can't provide a critical background or history without synthesizing external sources. To illustrate your theoretical framework, you need to synthesize a range of literature that defines the theory or theories you intend to use.

Therefore, as stated earlier in this guide, you should be prepared to review and synthesize a range of literature regardless of your discipline. You can tailor the purpose of that synthesis to the structure and demands of writing in your subject area.

Q: Does my literature review need to include every source I plan to use in my discussion chapter?

A: The short answer is 'no' - there are some situations in which it is okay to use a source in your discussion chapter that you didn't integrate into your literature review chapter.

Imagine, for example, that your study produced a surprising result: a finding that you didn't anticipate. To make sense of that result, you might need to conduct additional research. That new research will help you explain the unexpected result in your discussion chapter.

More often, however, your discussion will  draw on, or return to, sources from your literature review. After all, the literature review is where you paint a detailed picture of the conversation surrounding your research topic. Thus, it makes sense for you to relate your own work to that conversation in the discussion.

The literature review provides you an opportunity to engage with a rich range of published work and, perhaps for the first time, critically consider how your own research fits within and responds to your academic community. This can be a very invigorating process!

At the same time, it's likely that you will be juggling more academic sources than you have ever used in a single writing project. Additionally, you will need to think strategically about the focus and scope of your work: figuring out the best structure for your literature review might require several rounds of re-drafting and significant edits.

If you are usually a 'dive in without a plan and just get drafting' kind of writer, be prepared to modify your approach if you start to feel overwhelmed. Mind mapping, organising your ideas on a marker board, or creating a bullet-pointed reverse outline can help if you start to feel lost.

Alternately, if you are usually a 'create a strict, detailed outline and stick to it at all costs' kind of writer, keep in mind that long-form writing often calls for writers to modify their plans for content and structure as their work progresses and evolves. It can help such writers to schedule periodic 'audits' of their outlines, with the aim being to assess what is still working and what else needs to be added, deleted or modified.

Here’s a final checklist for writing your literature review. Remember that not all of these points will be relevant for your literature review, so make sure you cover whatever’s appropriate for your dissertation. The asterisk (*) indicates any content that might not be relevant for your dissertation. You can save your own copy of the checklist to edit using the Word document, below.

Are you tired of hearing the phrase 'literature review' every five minutes at university and having no idea what it means, let alone where to start? Not to worry - we've got you covered with this step-by-step guide to creating a great dissertation literature review.

What is a literature review?

In short, a dissertation literature review provides a critical assessment of the sources (literature) you have gathered and read surrounding your subject area, and then identifies a “gap” in that literature that your research will attempt to address.

There are a lot of misunderstandings about what exactly a dissertation literature review entails, as it can vary. Whilst in some cases a dissertation literature review can be a simple summary of important sources, most often it requires you to critically engage with the text to convey your positive or negative opinions of it. What is your interpretation of a particular source? Does this interpretation differ considerably from other viewpoints in the literature? This is the sort of critical engagement expected from you in a literature review.

Whereas a summary will most likely provide a simple recap of the general arguments of the source(s), the expectations concerning a literature review extend beyond this. A literature review may provide a new perspective on a classic research paper or it may combine both new and old interpretations (this is the “gap” – more on this later). A literature review may also provide a thorough and critical outline of the intellectual developments in a field with a focus on major, and often polemical, debates. In other scenarios, a literature review may also provide an assessment of a source and inform a reader about its validity, pertinence and relevance to the research subject.

"In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”."

There tends to be confusion between literature reviews and academic papers in general, but they are not one and the same. Generally, academic papers aim to provide new research material about a particular subject, and a literature review features as part of this objective. In a research paper, the literature review forms the basis of the research – it helps to highlight any research gaps as support for a new argument or insights you intend to provide. In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”.

Is a literature review really necessary?

Now that we know what a literature review is, the next step is to understand the point of writing one in the first place. Like it or not, a literature review is an essential part of any academic piece of writing, as it demonstrates to your tutor or reader that you have a nuanced understanding of the sources concerning your research area or question.

Although it may seem arbitrary, the literature review helps to persuade the person reading and marking your assignment that what you have written about is relevant and your arguments are justified and worthwhile. So, in short, a literature review is essential, and you need to put the necessary time into getting it right.

How do you write a dissertation literature review?

As the next section of this blog is quite lengthy, we've broken it down into several key steps which should make it easier to follow when writing your own dissertation literature review. You start by identifying your sources, then you read and re-read them. Next, you think about any gaps in the research or literature you have used, and finally, you write your review using all the preparation and information gathered in the steps prior.

Identify sources

To write a good dissertation literature review, you need to have a fair idea of what sources you would like to review. If you haven’t been given a formal reference list by your tutor, refer back to the techniques we recommended earlier.

Make sure that your sources are balanced; include enough books and academic journals and any useful published work from reputable scholars. To help you choose your sources appropriately, you might want to think about the parameters and objectives of your research. What are you hoping to find out? In your literature review , what theoretical issues or perspectives do you aim to tackle? How about your methodology? Will you focus on mainly qualitative or quantitative studies, or a mixture of both? These general questions should help guide you in selecting your sources and again, remember that the abstract of a source is a very useful tool. Having a quick scan of the abstract and its ‘keywords’ will often give you an indication of the whether the source will be useful for your research or not.

As you’re identifying your sources, ensure you a keep a list as it’s very easy to lose focus given the wide scope of the Internet. Reference tools such as Mendeley allow you to store your sources online and via a desktop app, and are a great way to keep your bibliography organised. The citation tools attached to these programmes will also allow you to simply export citations in a format of your choice when required later. They will save you countless hours trying to figure out how to use Harvard or APA referencing correctly.

Read your sources

Now that you have organised your sources efficiently, it’s time to read through them. As unnatural as it may feel, it’s most effective to read in a few stages, as detailed below:

First, go through all the texts to get a sense of their general content and arguments. This will also help you judge which sources you mainly want to focus on in your review. During the second stage of your reading, you can then take a more critical, in-depth look at your sources. Make a lot of notes, be critical, ask questions. What is your academic opinion on the text? Do you have any comments on the methodological approach, the theoretical argument or the general hypothesis? Note these down. It will ensure that your literature review is not merely a summary of your readings, and will encourage a clear line of argument so that your work is logical and coherent.

Consider gaps in the research

When writing a dissertation literature review, an essential thing to consider is identifying the research gap. Identifying the gap is particularly important if your review forms part of a research proposal, as it will highlight the pertinence of your research – assuming that your research has been designed to fill this gap. In other instances, identifying the gap is an indication of good critical analysis and can score you extra points.

To identify the “gap” it is important that we know what this “gap” is. A research gap is essentially the existence of a research question, perspective or problem that has not been answered in the existing literature on any field of study. Identifying the research gap is important for highlighting the originality of your research; it proves you’re not simply recounting or regurgitating existing research. It also shows that you are very much aware of the status of the literature in your chosen field of study, which in turn, demonstrates the amount of research and effort you have put into your review.

Many students, especially at post-graduate level, find it extremely difficult to identify research gaps in their subject area. For post-graduate research papers, identifying research gaps and formulating research questions that can address these gaps form the very essence of a research paper. Identifying research gaps does not have to be a difficult endeavour and there are several ways to overcome this difficulty:

Start by reading A simple approach will be to read important parts of key articles in your research area. First, note that you’ll have to sift through many articles to identify the ones that are most suitable for your research. A quick search using keywords on Google Scholar will often give you a quick overview of the available literature. Other useful sources include databases such as JSTOR or Wiley Online Library . You can then snowball additional articles by clicking on ‘related articles’ or checking out which other papers have cited your source.

Abstracts and recommendations Whichever avenue you choose, reading the abstract is often a good starting point to get a sense of what the articles entails. You should also do a quick examination of the introductory and concluding paragraphs of the paper as these sections always provide some information on the aims and outcomes of the research, as well as ‘recommendations for future studies.’ These recommendations typically provide some insight on the research gaps in the literature. Another route would be to simply read as much as you can on your research subject while considering which research areas still need addressing in the literature – this is usually an indication of research gaps.

Write your review

Now you’re well prepared to start putting fingers to keyboard. Consider the following pointers:

1. Use sample literature reviews Have a look at sample dissertation literature reviews in your subject area and read them thoroughly to familiarise yourself with existing key debates and themes. This can be a good starting point for framing and structuring your own review. If you are not familiar with academic writing, going through samples will help you to get a sense of what is expected in this regard. Pay attention to the academic language and formal style used. Also, remember that the bibliography or reference section of your selected texts will help you to snowball further references if you need any.

2. Keep it simple Keep your topic as narrowed down as possible. Remember that there are hundreds – or in some instances, thousands – of sources or perspectives concerning any subject area or topic. Researchers investigate research problems in many divergent ways and the literature available on any given subject is extremely broad. In your literature review, you won’t be expected to address every argument or perspective concerning your topic – this might actually undermine your ability to write a coherent and focused piece. You’ll make your work easier if you limit the scope of your work. In your review, ensure that you clearly state what the focus of your work will be.

3. Make sure your sources are as current as possible If you are reviewing scientific work, it’s essential your sources are as current as possible given the advancements in the field over the years. In the medical field particularly, research is constantly evolving and a source that’s only three years old may be even out-dated. In the social sciences this rule may not apply, as many theoretical works are classics and you will be expected to be familiar with these perspectives. You might have to the review the work of Marx, or Hobbes, or any other classic scholar. You still need to balance theory with current approaches, as you will need to demonstrate the ways in which perspectives in the literature have changed over the years, or you may even want to demonstrate how scholars have used classic theories to inform their work.

4. Consider the organisation of your work In a dissertation literature review, organising your work goes beyond having an introduction, body and conclusion. You’ll be reviewing a number of texts, so you’ll also have to think clearly about how to organise themes, topics and your argument in general. Below is a detailed guide on how to do this:

Like any other academic paper, a dissertation literature review will comprise a basic introduction, body, and conclusion.

The introduction of a literature review should be clear, short and focused. It should outline the focus of the review – in other words, it should clearly state the main topics to be covered. A good literature review will also state the arguments to be made, as well as underlying rationale that underpins these arguments.

The body of your literature review will include an in-depth discussion of the academic sources you have chosen to review. You may choose to organise your sources according to themes, methodology or even based on a chronological order. In the body of your review, ensure that your arguments are presented clearly and that you link these arguments with the literature. Is there a scholar that agrees with your view? Say so, in a way that the reader will understand easily. This demonstrates that you are very familiar with the academic research in your field. Remember to also make note of any views that do not agree with your position; excluding these arguments will reduce the methodological robustness of your piece. You can use direct quotations in your literature review, however do so sparingly so you don’t appear lazy. Most tutors will not approach it kindly; the purpose of a literature review is to demonstrate your ability to critically engage with a piece of text, and littering your review with direct quotes isn’t a good indication of this. Instead, try to paraphrase quotations and only use direct quotes if it really helps to illustrate your argument.

In the summary of your dissertation literature review, it’s important to give a summary of the conclusions you’ve drawn from your readings. If your literature review forms part of a broader research proposal, reiterate the gaps in the literature here, and clearly state how your proposed research will fill these gaps. Make recommendations for future research in this section too, which demonstrates your analytical skills and will score you some extra points.

You now have the basic structure of your research in place, however it’s worth dedicating some time to what the body of your work should entail. The body is the main core of your work, so it’s important to consider how you will frame and organise it. You have options here – you can choose to organise the content of your work based on a chronological method, based on themes, trends or methodology, or based on arguments.

To structure the body of work chronologically, you will have to organise your sources based on when they were published. A limitation of this approach is that it inhibits continuity in your arguments and in some instances, can undermine the coherence of your work. Use with caution.

A more coherent way of organising your work is to group your sources based on the arguments they make in a ‘for versus against’ manner. This enables you to present your work in a more dynamic way and what’s more, makes the key debates in the literature more obvious. Say you were trying to convey the debates on European migration policy, you might want to start by writing something along these lines:

"While scholars such as X argue that migration policies must be made more stringent to counteract the increased flow of Syrian refugees to Europe, other scholars such as Y offer a divergent perspective. They specifically espouse a perspective based on a human rights approach…"

This approach also leaves room for you to insert your voice into the literature. Consider this statement:

"While X argues for the enactment of more stringent migration policies, this paper argues along the lines of Y that migration policies should be based on human rights considerations."

Using this technique also allows you to introduce additional literature that supports your position.

Another way of organising your content is according to theme; or sub-themes, if your review focuses on one overarching topic. This method of organisation still allows you to present an overview of any polemical debates within these sub-themes. A thematic review can easily shift between chronological periods within each sub-section too.

Structuring work using a methodological approach is quite a common approach, however it’s often used in tandem with other ways of organising sources. This method is particularly evident in introductory sections whereby researchers may simply want to state that a particular subject has been mostly studied from a qualitative or quantitative perspective (they will often then cite a number of scholars or studies to support this claim). In scientific reviews however, a methodological approach may form the basis of the discussions in the body. If this is the case for you, focus on the methods used by various researchers. How did they go about answering a particular research question? Were there any limitations to this method? If so, what method(s) would have been better?

You’ll soon realise that organising the body of your literature review is an iterative process and you’ll more often than not use all of these approaches in your write-up. The body of your research may also include additional sections that do not necessarily form a part of its organisational structure. For instance, you might want to include a ‘context section’ that provides some insight on any background detail required for understanding the focus of the literature review. It may also focus on historical considerations. You could include a short methodology section that details the approach you used in selecting and analysing your sources.

5. Write the paragraphs of the body Once you have settled on the approach to writing your body, you must now write each of its paragraphs in a way that is in keeping with academic conventions. Consider this paragraph from a literature review about stakeholder participation for environmental management, to clarify the discussion that follows:

Despite the rhetoric and the concerns that have been expressed, there have been few attempts to investigate the validity of the many claims that have been made for stake-holder participation (Webler, 1999; Beierle, 2002; Brody, 2003; Blackstock et al., 2007). The few attempts that have been made have tended to focus on evaluating the process rather than the outcomes (e.g. Beierle, 2002; Renn et al., 1995; Rowe and Frewer, 2000). This may be partly due to the challenge of selecting appropriate evaluation criteria and data collection methods. Blackstock et al., 2007 argue that the evaluation of participatory processes should itself be participatory, with stakeholders selecting and applying the evaluation criteria. However, this is not straightforward. Webler and Tuler (2006) found strong differences of opinion between participants that they selected from ten case studies, about what constituted a "good" participatory process. (Source: Reed, M.S., 2008. Stakeholder participation for environmental management: a literature review. Biological conservation, 141(10), pp.2417-2431).

As the example above suggests, a dissertation literature review must be written using a formal and academic style . Also, note how sources have been grouped according to both arguments and themes. Remember we noted that the process of grouping sources in the body of your literature review is never a linear one? You will often use a combination of the approaches that we have discussed. Ensure that your writing is concise, coherent and devoid of any personal or strong language. Avoid any phrases like, “I hate X’s work”; a more academic way of stating your disagreement would be to simply state: “I would argue against X’s position that…”, or “X’s argument is inconsistent with the evidence because...”, or “X’s arguments are based on false assumptions because...”.

In the sample paragraph above, notice the use of words like “argue” – this is a good academic alternative to more commonplace words such as “says”. Other good alternatives include “states”, “asserts”, “proposes” or “claims”. More academic options include “opine”, “posit”, “postulate”, or “promulgate”, however some tutors and readers find these words to be too ‘heavy’ and archaic, so ensure that you are familiar with the writing standards in your institution.

If your writing is tailored to a peer-reviewed journal, it’s worth having a look at articles within that journal to get a sense of the writing style. Most tutors will provide a guideline on writing styles, and it’s important you adhere to this brief. You will often be required to also use the third person when writing a literature review, thus phrases such as “this paper argues” or “this paper is of the view that…” are appropriate.

There are exceptions at post-graduate level or generally – like when you have conducted your own primary research or published your work widely – which give you the academic authority to boldly make claims. In cases like these, the use of first person is suitable and you may use phrases such as “I argue” or “I propose”.

Remember also to generally use present tense when referring to opinions and theories (although in the context of specific research experiments, the use of the past tense is better).

Beyond the use of the academic terms suggested above, ‘linking’ words are also particularly important when writing a literature review, since you’ll be grouping a lot of writers together with either similar or divergent opinions. Useful linking words and phrases include: similarly, there are parallels, in convergence with…

When there is disagreement, you may want to use any of the following: However, conversely, on the other hand, diverges from, antithetical to, differential from…

6. Write the conclusion The conclusion of a dissertation literature review should always include a summary of the implications of the literature, which you should then link to your argument or general research question.

Some final notes

The overall structure of your literature review will be largely based on your research area and the academic conventions that are in line with it. Nevertheless, there are some essential steps that apply across all disciplines and that you should ensure you follow:

Do not simply describe the opinions of writers Analyse, analyse, analyse, and ensure that your analysis is critical (what have the writers missed; where does your opinion sit with theirs, etc.).

Structure the body of your argument using various techniques Your structure should be organised based on thematic areas, key debates or controversial issues, and according to methodological approaches. Keep your review dynamic, but coherent. Remember to identify literature gaps and link this to your own research.

Use ample evidence This is extremely important and forms the very essence of a dissertation literature review. You must refer to various sources when making a point; see the sample paragraph above for an example of this. Your arguments and interpretation of a research topic must be backed by evidence. Do not make baseless claims, as a literature review is an academic piece of writing and not an opinion piece.

Be very selective Not every piece of research has to be reviewed. If you are determined to show that you aware of the available literature out there, try writing techniques such as: There is robust literature available concerning the migration patterns of Syrian refugees. Notable works include: X(2015), y (2013), Z (2014). Once you have acknowledged these works, you do not have to review them in detail. Be selective about the sources that you will discuss in detail in your review.

Do not rely too much on direct quotes Only use them to emphasise a point. Similarly, don’t rely too heavily on the work of a single author. Instead, highlight the importance of that author in your research and move on. If you need to keep going back to the work of that author, then you need to link those discussions with your work. Do not simply provide a summary of the author’s work. In what ways does your work agree or disagree with his/hers? Be critical.

Make your voice heard Yes, the whole point of the literature review is to provide a critical analysis and summary of the viewpoints out there, but a critical analysis does include the fact that you need to make your opinion known in the context of the literature. Note how skilfully, in the earlier sample paragraph by Reed (2008), he weaves his opinions with references. Read back over the sample and try to perfect this skill.

Ensure that you reference your work correctly And make sure you use the appropriate referencing style. For more help on this, click here .

Written by: Katherine Watson

Starting a literature review can be a daunting task. A literature review is a foundational aspect of a dissertation, but you may also be asked to produce a standalone literature review. You may be unfamiliar with the term literature review, and the first thing to note is that it is not that different to essays you are used to writing….

What is a literature review?

A literature review is a critical summary of existing work on a chosen topic. Importantly, it is not a list or description of ALL texts relevant to your topic. Your literature review should pick up on important ideas, debates, theories, methods and omissions across this body of literature. Rather than repeating or re-wording this information, a literature review represents your own evaluations and comparisons between these texts and should highlight your key take-aways from those readings.

What are the main functions of a literature review?

• Demonstrate that you have read widely on your topic and have a strong understanding.
• Recognise existing work.
• (In the context of a dissertation) Create the foundation for your research and justify the direction, methods and questions you pursue.
• (In the context of a dissertation) Introduce the background concepts and theories which will underpin your discussion chapter.

Step 1: Gathering literature

• Key words / search terms. Devise several key words or search terms that encapsulate your research topic.
• Use online research engines. Input your key words into free online search engines. iFind  by Swansea University is a great place to start. Other options include Google Scholar, ResearchGate, ScienceDirect and Social Science Research Network. There are also discipline specific search engines such as PubMed Central for healthcare and science. There are pros and cons to different search engines in terms of their coverage and accuracy, so it’s worth using at least two to gain access to a fuller range of literature. Be very systematic!
• Check bibliographies. Utilise the bibliography of relevant journal articles or books to gather even more references. This can be particularly useful for locating older publications which may not be flagged on search engines.
• Talk to a librarian. Librarians are experts in conducting literature searches. If you are lost about where and how to find literature contact them early and discuss the questions you’re asking, the problem you’re addressing and area you’re working on. They may be able to suggest online databases, journals and books.

Step 2: Organising literature

• Start collating an accurate record of sources on a Word document or Excel spreadsheet. Be sure to note the title, author(s), and date. You may copy and paste the abstract and key words or write your own summary. However, keep space to add your own evaluation of the literature (see below).
• Create a logical structure whether that be chronological or thematic. The advantage of creating a table in an Excel spreadsheet is that you can reorder your sources according to when they were published or another criterion.

Step 3: Critical reading

It is important to be selective, you don’t have time to read everything. Tips on how to be a more effective and efficient reader can be found on  Read Right, Write Right.

While the body of literature may be large, you will typically find repetition and common ground between texts. Make a note of these similarities, as well as where approaches or arguments diverge and contrast.

Weed out any sources which are not relevant after your reading and consolidate your list/table of core literature.

Step 4: Critical analysis

This is your opportunity to elaborate on your record of core literature by producing your own summary and reflection of the texts. Return to any notes you’ve written already and re-read relevant sections of the texts if necessary. Don’t just repeat their arguments (though you may note down a small number of quotations). Keep your focal topic at the front of your mind!

The questions listed below can be used as prompts to get you thinking critically:

• What are the main theories/concepts/methods/approaches being used? How are they justified? What are its key features?
• Are the conclusions logical and well supported?
• Does the information fit with what you already know?
• Does it contradict or dispute other evidence or arguments?
• Are there gaps or limitations? Has the author overlooked or misunderstood anything?
• How can you use this in your own work?

As you think, WRITE !  What to do with all of those notes  will help you process your ideas, and these notes will likely find their way into your literature review as your start to write it up formally.

Length of a master's thesis and its literature review?

I am pretty confident that I will be getting answers pointing out that this is something too specific and should/will be decided by my university and that a general answer does not exist. But anyway, I just want to have an idea.

I was aiming at 120 pages of my upcoming marketing master's thesis but I thought that I could reduce it to 100 (pure text speaking of course as I am pretty sure that with references and appendices, it will be +120 though). So what is the average length of a master's thesis? Business and marketing field. As for what I've found online, the general consensus seems to be between 60 and 120 pages.

As for its literature review length, again, the general consensus seems to be between 20% and 40% of the overall thesis length, any personal experience with that? I was aiming at 50% but after doing some research, I am decreasing it to somewhere between 20% and 30%. However my instructor demanded it to be between 30% and 40%.

• That seems like a lot to me. I'ld say max 15,000 words similar to an article published in a marketing journal..... –  Tim Commented Jun 22, 2016 at 3:51
• You mean the thesis' length or the literature review? 15,000 is around 30 pages so that makes it 30% if I am planning at 100 pages of the thesis. –  R. AS. Commented Jun 22, 2016 at 9:23
• 1 Your school should have prior master's theses available either online or in the library. Take a look at them, especially ones with the same advisor. What's acceptable at my school isn't going to be what's acceptable at yours, and what's acceptable to my advisor isn't necessarily going to fly with yours. –  Kathy Commented Jun 22, 2016 at 13:59

2 Answers 2

I found 5 theses related to my master's thesis topic on the Open Access Theses and Dissertations website. All of them were 120 pgs - 150 pages, although this was for engineering. The literature review was (appx) 30% of each thesis. My suggestion is to check the OATD website, find theses in your field and closely related to your topic to get a pretty general idea of the length and breadth of literature review.

• Will definitely check. The ones you've checked, were references/appendices part of the 120 - 150 pages? –  R. AS. Commented Jun 22, 2016 at 9:22

I think you pretty much answered your question yourself (as you expected). You seem to have a good idea of what the length of related theses is and you know that your university has the last word. 100 to 120 pages seems reasonable for your area.

If you really want to know you have to ask you advisor or former students who already wrote their thesis in a related subject.

Skills for Learning : Dissertations & Literature Reviews

Dissertations  are extended projects in which you choose, research and write about a specific topic. They provide an opportunity to explore an aspect of your subject in detail. You are responsible for managing your dissertation, though you will be assigned a supervisor. Dissertations are typically empirical (based on your own research) or theoretical (based on others’ research/arguments).

The  Dissertation IT Kit  contains information about formatting your dissertation document in Word.

Look at the  Library Subject Guides  for your area. These have information on finding high quality resources for your dissertation. 

We run interactive workshops to help you prepare for your dissertation. Find out more on the  Skills for Learning Workshops  page.

You can work through the modules at your own pace, revisiting them as required. Find out more from our FAQ  What academic skills modules are available?  

Dissertation proposals

What are dissertation proposals.

A dissertation proposal is an outline of your proposed research project. It is what you imagine your dissertation might look like before you start. Consider it a temporary document which might change during the negotiation process between you and your dissertation supervisor.  The proposal can help you clarify exactly what you want to cover in your dissertation. It can also outline how you are going to approach it. Your dissertation plan and structure might change throughout this process as you develop your ideas. Your proposal is the first step towards your goal: a completed dissertation.

Structuring your dissertation proposal

The structure, content, and length of your dissertation proposal will depend on your course requirements. Some courses may require that your aims and objectives are separate from the main body of the proposal. You might be expected to write a literature review, and/or provide a detailed methodology. You might also be asked to include an extensive context for your proposed study. Consult your module handbook or assignment brief for the specific requirements of your course. 

Give each section of your proposal a heading You can also experiment with giving your proposed dissertation a title. Both of these approaches may help you focus and stay on topic. Most dissertation proposals will have a fairly standard structure, under the following headings:

Sections of a dissertation proposal

• Aims and objectives
• Rationale for your study
• Methodology
• Brief literature review
• Benefits of your research

Describe what you plan to investigate. You could write a statement of your topic, a research question(s), or a hypothesis.

• Explain why you want to do this research.
• Write a justification as to why the project is worth undertaking.
• Reasons might include: a gap in existing research; questioning or extending the findings of earlier research; replicating a piece of research to test its reliability.
• Describe and justify how you plan to do the research.
• You might be reviewing the work of others, which mainly involves secondary, or desk-based, research. Or you might plan to collect data yourself, which is primary research. It is common for undergraduate dissertations to involve a mixture of these.
• If you are doing secondary research, describe how you will select your sources. For primary research, describe how you will collect your data. This might include using questionnaires, interviews, archival research, or other methods. 
• Others will have researched this topic before, or something similar.
• The literature review allows you to outline what they have found and where your project fits in. For example, you could highlight disagreements or discrepancies in the existing research.

Outline who might potentially gain from your research and what you might find out or expand upon. For example, there could be implications for practice in a particular profession.

Dissertation style and language

A dissertation is a logical, structured, argument-based exploration of a topic. The style of your writing may vary slightly in each chapter. For example, your results chapter should display factual information, whereas your analysis chapter might be more argument-based. Make sure your language, tone and abbreviations are consistent within each section. Your language should be formal and contain terminology relevant to your subject area. Dissertations have a large word count. It is important to structure your work with headings and a contents page. Use signposting language to help your reader understand the flow of your writing. Charts, tables or images may help you communicate specific information. 

Top tip!  To signpost in your dissertation, use the ‘Signalling Transition’ section of the  Manchester Academic Phrasebank .

Past dissertations

Exploring past dissertations within your academic field can give you an idea as to how to structure your dissertation and find similar research methodologies. You can access dissertations and theses completed by students at Leeds Beckett and other universities. To find external dissertations, look at our FAQ answer ' Are there other dissertations I can look at?' . To find dissertations completed by Leeds Beckett students, use the FAQ answer ' Can I find copies of past dissertations in the Library? '

Sections of a dissertation

Not all dissertations will follow the same structure.  Your style can change depending on your school. Check your module handbook, assignment brief or speak with your course tutor for further guidance.

To decide what to include:

• Think about your project from an outsider’s perspective. What do they need to know and in what order? What is the most clear and logical way for you to present your research?  
• Discuss your project with your supervisor. Be open about ideas or concerns you have around the structure and content. 

Each section of a dissertation has a different purpose. Think about whether you're doing an empirical or theoretical dissertation and use the headings below to find out what you should be including.

You can also use the Leeds Beckett Dissertation Template to help you understand what your dissertation should look like. 

• Leeds Beckett Dissertation Template

For more information on dissertation style, language and structure, watch a recording of our interactive workshop below.

Empirical (research-based)

• 1. Abstract
• 2. Contents Page
• 3. Introduction
• 4. Literature Review
• 5. Methodology
• 6. Findings / Results
• 7. Discussion
• 8. Conclusion
• 9. Reference List / Bibliography
• 10. Appendices

Abstract : provides a brief summary of your whole dissertation.

The abstract outlines the purpose of your research and your methodology (where necessary). You should summarise your main findings and conclusion.

Top tips! Give the reader a sense of why your project is interesting and valuable. Write in the past tense. Aim for about half a page.

Contents page : lists all the sections of your dissertation with the page numbers. Do this last by using the automatic function in Word.

Introduction: introduces the reader to your research project.

Provide context to the topic and define key terms. Ensure that the scope of your investigation is clear. Outline your aims and objectives, and provide a brief description of your research methods. Finally, give an indication of your conclusion/findings.

Top tips! Start broad (background information) and get more specific (your research aims and findings). Try writing the introduction after the literature review and methodology chapters. This way, you will have a better idea of your research aims.

Literature Review : positions your research in relation to what has come before it.

The literature review will summarise prior research on the topic, such as journal articles, books, government reports and data. You should introduce key themes, concepts, theories or methods that provide context for your own research. Analyse and evaluate the literature by drawing comparisons and highlighting strengths and weaknesses. Download the Critical Analysis Questions and Evidence Matrix Worksheets to help you with this process and for more information on literature searching see Finding Information .

• Critical Analysis Questions Worksheet
• Evidence Matrix Worksheet

The literature review should justify the need for your research and highlight areas for further investigation. Avoid introducing your own ideas at this point; instead, compare and comment on existing ideas.

Top tips! Your literature review is not a descriptive summary of various sources. You need to synthesise (bring together) and critically analyse prior research. Sophisticated use of reporting verbs is important for this process. Download our Reporting Verbs Worksheet to help you with this.

Methodology : provides a succinct and accurate record of the methodology used and justifies your choice of methods.

In this section, you describe the qualitative and/or quantitative methods* used to carry out your research/experiment. You must justify your chosen research methodology and explain how it helps you answer your research question. Where appropriate, explain the rationale behind choices such as procedures, equipment, participants and sample size. You may need to reference specific guidelines that you have used, especially in subjects such as healthcare. If your research involves people, you may also need to demonstrate how it fulfils ethical guidelines.

Top tips! Your account should be sufficiently detailed so that someone else could replicate your research. Write in the passive voice. Remember, at this point you are not reporting any findings.

*Qualitative research is based on opinions and ideas, while quantitative research is based on numerical data.

Find out more about the research process.

Findings/Results : presents the data collected from your research in a suitable format.

Provide a summary of the results of your research/experiment. Consider the most effective methods for presenting your data, such as charts, graphs or tables. Present all your findings honestly. Do not change any data, even if it is not what you expected to find.

Top tips! Whilst you might acknowledge trends or themes in the data, at this stage, you won’t be analysing it closely. If you are conducting qualitative research, this section may be combined with the discussion section. Important additional documents, such as transcriptions or questionnaires, can be added to your appendices.

Discussion : addresses your research aims by analysing your findings.

In this chapter, you interpret and discuss your results and draw conclusions. Identify trends, themes or issues that arise from the findings and discuss their significance in detail. These themes can also provide the basis for the structure of this section. You can draw upon information and concepts from your literature review to help interpret your findings. For example, you can show how your findings build upon or contradict earlier research.

Top tips! Ensure that the points you make are backed up with evidence from your findings. Refer back to relevant information from your literature review to discuss and interpret your findings.

Conclusion : summarises your main points.

Provide an overview of your main findings and demonstrate how you have met your research objectives. Set your research into a wider context by showing how it contributes to current academic debates. Discuss the implications of your research and put forward any recommendations.

Top tips! Do not introduce any new information in this section. Your conclusion should mirror the content of your introduction but offer more conclusive answers.

Reference List / Bibliography : a complete list of all sources used.

List all the sources that you have consulted in the process of your research. Your Reference List or Bibliography must follow specific guidelines for your discipline (e.g. Harvard or OSCOLA). Look through your module handbook or speak to your supervisor for more information.

Appendix (single) or Appendices (plural):  presents raw data and/or transcripts that aren’t in the main body of your dissertation.

You may have to be selective in the data you present in your findings section. If this is the case, you may choose to present the raw data/extended version in an appendix. If you conduct qualitative research, such as interviews, you will include the transcripts in your appendix. Appendices are not usually included in the word count.

Top tips! Discuss with your supervisor whether you will need an appendix and what to include.

Theoretical (argument based)

• Contents page
• Introduction
• Literature Review
• Main body (divided into chapters)
• Reference list / Bibliography

Provides a brief summary of your whole dissertation.

The abstract outlines the purpose of your research and your methodology (where necessary). You should summarise your main findings and conclusion.

Top tip!  Give the reader a sense of why your project is interesting and valuable. Write in the past tense. Aim for about half a page.

Contents page : lists all the sections of your dissertation with the page numbers. Using the automatic table of contents feature in Microsoft Word can help you format this.

The  Dissertation IT kit provides guidance on how to use these tools. 

Introduces the reader to your research project.

Provide context to the topic and define key terms. Ensure that the scope of your investigation is clear. Outline your aims and objectives, and provide a brief description of your research methods. Introduce your argument and explain why your research topic is important. Finally, give an indication of your conclusion/findings.

Top tip!  Start broad (background information) and get more specific (your research aims and findings). Try writing the introduction after the literature review and methodology chapters. This way, you will have a better idea of your research aims.

Summarises prior research on the topic, such as journal articles, books, and other information sources. You should introduce key themes, concepts, theories or methods that provide context for your own research. You should also analyse and evaluate the literature by drawing comparisons and highlighting strengths and weaknesses. 

Many (although not all) theoretical dissertations will include a separate literature review. You may decide to include this as a separate chapter. Otherwise, you can integrate it into your introduction or first themed chapter.

Find out more about literature reviews on the  Literature Reviews  page.

Divide the main body of your research into chapters organised by chronology or themes. Each chapter should be like a mini-essay that helps you answer your research questions. Like an essay, each chapter should have an introduction, main body and conclusion. Develop your argument and demonstrate critical thinking by drawing on relevant sources. Compare and contrast ideas, and make suggestions or recommendations where relevant. Explain how each chapter helps answer your main research question.

Top tip! Divide each chapter into chunks and use subheadings where necessary to structure your work.

Find out more on the  Critical Thinking  pages. 

Top tip!  Do not introduce any new information in this section. Your conclusion should mirror the content of your introduction but offer more conclusive answers.

List all the sources that you have consulted in the process of your research. Your Reference List or Bibliography must follow specific guidelines for your discipline (Harvard, APA or OSCOLA). Look through your module handbook or speak to your supervisor for more information.

Appendix (single) or Appendices (plural):  presents any data, such as images or tables, that aren’t in the main body of your dissertation.

You may have to be selective about the information you include in the main body of your dissertation. If this is the case, you may place data such as images or tables in the appendix. Appendices are not usually included in the word count.

Top tip!  Discuss with your supervisor whether you will need any appendices and what to include.
