How to Write a Bibliography for a Research Paper

Academic Writing Service

Do not try to “wow” your instructor with a long bibliography when your instructor requests only a works cited page. It is tempting, after doing a lot of work to research a paper, to try to include summaries on each source as you write your paper so that your instructor appreciates how much work you did. That is a trap you want to avoid. MLA style, the one that is most commonly followed in high schools and university writing courses, dictates that you include only the works you actually cited in your paper—not all those that you used.

  • If your assignment calls for a bibliography, list all the sources you consulted in your research.
  • If your assignment calls for a works cited or references page, include only the sources you quote, summarize, paraphrase, or mention in your paper.
  • If your works cited page includes a source that you did not cite in your paper, delete it.
  • All in-text citations that you used at the end of quotations, summaries, and paraphrases to credit others for their ideas,words, and work must be accompanied by a cited reference in the bibliography or works cited. These references must include specific information about the source so that your readers can identify precisely where the information came from.The citation entries on a works cited page typically include the author’s name, the name of the article, the name of the publication, the name of the publisher (for books), where it was published (for books), and when it was published.

The good news is that you do not have to memorize all the many ways the works cited entries should be written. Numerous helpful style guides are available to show you the information that should be included, in what order it should appear, and how to format it. The format often differs according to the style guide you are using. The Modern Language Association (MLA) follows a particular style that is a bit different from APA (American Psychological Association) style, and both are somewhat different from the Chicago Manual of Style (CMS). Always ask your teacher which style you should use.

A bibliography usually appears at the end of a paper on its own separate page. All bibliography entries—books, periodicals, Web sites, and nontext sources such radio broadcasts—are listed together in alphabetical order. Books and articles are alphabetized by the author’s last name.

Most teachers suggest that you follow a standard style for listing different types of sources. If your teacher asks you to use a different form, however, follow his or her instructions. Take pride in your bibliography. It represents some of the most important work you’ve done for your research paper—and using proper form shows that you are a serious and careful researcher.

Bibliography Entry for a Book

A bibliography entry for a book begins with the author’s name, which is written in this order: last name, comma, first name, period. After the author’s name comes the title of the book. If you are handwriting your bibliography, underline each title. If you are working on a computer, put the book title in italicized type. Be sure to capitalize the words in the title correctly, exactly as they are written in the book itself. Following the title is the city where the book was published, followed by a colon, the name of the publisher, a comma, the date published, and a period. Here is an example:

Format : Author’s last name, first name. Book Title. Place of publication: publisher, date of publication.

  • A book with one author : Hartz, Paula.  Abortion: A Doctor’s Perspective, a Woman’s Dilemma . New York: Donald I. Fine, Inc., 1992.
  • A book with two or more authors : Landis, Jean M. and Rita J. Simon.  Intelligence: Nature or Nurture?  New York: HarperCollins, 1998.

Bibliography Entry for a Periodical

A bibliography entry for a periodical differs slightly in form from a bibliography entry for a book. For a magazine article, start with the author’s last name first, followed by a comma, then the first name and a period. Next, write the title of the article in quotation marks, and include a period (or other closing punctuation) inside the closing quotation mark. The title of the magazine is next, underlined or in italic type, depending on whether you are handwriting or using a computer, followed by a period. The date and year, followed by a colon and the pages on which the article appeared, come last. Here is an example:

Format:  Author’s last name, first name. “Title of the Article.” Magazine. Month and year of publication: page numbers.

  • Article in a monthly magazine : Crowley, J.E.,T.E. Levitan and R.P. Quinn.“Seven Deadly Half-Truths About Women.”  Psychology Today  March 1978: 94–106.
  • Article in a weekly magazine : Schwartz, Felice N.“Management,Women, and the New Facts of Life.”  Newsweek  20 July 2006: 21–22.
  • Signed newspaper article : Ferraro, Susan. “In-law and Order: Finding Relative Calm.”  The Daily News  30 June 1998: 73.
  • Unsigned newspaper article : “Beanie Babies May Be a Rotten Nest Egg.”  Chicago Tribune  21 June 2004: 12.

Bibliography Entry for a Web Site

For sources such as Web sites include the information a reader needs to find the source or to know where and when you found it. Always begin with the last name of the author, broadcaster, person you interviewed, and so on. Here is an example of a bibliography for a Web site:

Format : Author.“Document Title.” Publication or Web site title. Date of publication. Date of access.

Example : Dodman, Dr. Nicholas. “Dog-Human Communication.”  Pet Place . 10 November 2006.  23 January 2014 < http://www.petplace.com/dogs/dog-human-communication-2/page1.aspx >

After completing the bibliography you can breathe a huge sigh of relief and pat yourself on the back. You probably plan to turn in your work in printed or handwritten form, but you also may be making an oral presentation. However you plan to present your paper, do your best to show it in its best light. You’ve put a great deal of work and thought into this assignment, so you want your paper to look and sound its best. You’ve completed your research paper!

How to Write a Bibliography in APA Format

  • How to Create One
  • Why You Need It

Sample Bibliography

An APA format bibliography lists all of the sources that might be used in a paper. A bibliography can be a great tool to help you keep track of information during the research and writing process. In some cases, your instructor may require you to include a bibliography as part of your assignment.

At a Glance

A well-written APA format bibliography can help you keep track of information and sources as you research and write your psychology paper. To create a bibliography, gather up all of the sources that you might use in your paper. Create an APA format reference for each source and then write a brief annotation. Your annotation should be a brief summary of what each reference is about. You can quickly refer to these annotations When writing your paper and determine which to include.

What Is an APA Format Bibliography?

An APA format bibliography is an alphabetical listing of all sources that might be used to write an academic paper, essay, article, or research paper—particularly work that is covering psychology or psychology-related topics. APA format is the official style of the American Psychological Association (APA). This format is used by many psychology professors, students, and researchers.

Even if it is not a required part of your assignment, writing a bibliography can help you keep track of your sources and make it much easier to create your final reference page in proper APA format.

Creating an APA Bibliography

A bibliography is similar in many ways to a reference section , but there are some important differences. While a reference section includes every source that was actually used in your paper, a bibliography may include sources that you considered using but may have dismissed because they were irrelevant or outdated.

Bibliographies can be a great way to keep track of information you might want to use in your paper and to organize the information that you find in different sources. The following are four steps you can follow to create your APA format bibliography.

Start on a New Page

Your working bibliography should be kept separate from the rest of your paper. Start it on a new page, with the title "Bibliography" centered at the top and in bold text. Some people use the title "References" instead, so it's best to check with your professor or instructor about which they prefer you to use.

Gather Your Sources

Compile all the sources you might possibly use in your paper. While you might not use all of these sources in your paper, having a complete list will make it easier later on when you prepare your reference section.

Gathering your sources can be particularly helpful when outlining and writing your paper.

By quickly glancing through your working bibliography, you will be able to get a better idea of which sources will be the most appropriate to support your thesis and main points.

Reference Each Source

Your references should be listed alphabetically by the author’s last name, and they should be double-spaced. The first line of each reference should be flush left, while each additional line of a single reference should be a few spaces to the right of the left margin, which is known as a hanging indent.

The format of each source is as follows for academic journals:

  • Last name of first author (followed by their first initial)
  • The year the source was published in parentheses
  • The title of the source
  • The journal that published the source (in italics)
  • The volume number, if applicable (in italics)
  • The issue number, if applicable
  • Page numbers (in parentheses)
  • The URL or "doi" in lowercase letters followed by a colon and the doi number, if applicable

The following examples are scholarly articles in academic journals, cited in APA format:

  • Kulacaoglu, F., & Kose, S. (2018). Borderline personality disorder (BPD): In the midst of vulnerability, chaos, and awe.  Brain sciences ,  8 (11), 201. doi:10.3390/brainsci8110201
  • Cattane, N., Rossi, R., & Lanfredi, M. (2017). Borderline personality disorder and childhood trauma: exploring the affected biological systems and mechanisms.  BMC Psychiatry,   18 (221). doi:10.1186/s12888-017-1383-2

Visit the American Psychological Association's website for more information on citing other types of sources including online media, audiovisual media, and more.

Create an Annotation for Each Source

Normally a bibliography contains only references' information, but in some cases you might decide to create an annotated bibliography. An annotation is a summary or evaluation of the source.

An annotation is a brief description of approximately 150 words describing the information in the source, your evaluation of its credibility, and how it pertains to your topic. Writing one of these for each piece of research will make your writing process faster and easier.

This step helpful in determining which sources to ultimately use in your paper. Your instructor may also require it as part of the assignment so they can assess your thought process and understanding of your topic.

Reasons to Write a Bibliography

One of the biggest reasons to create an APA format bibliography is simply to make the research and writing process easier.

If you do not have a comprehensive list of all of your references, you might find yourself scrambling to figure out where you found certain bits of information that you included in your paper.

A bibliography is also an important tool that your readers can use to access your sources.

While writing an annotated bibliography might not be required for your assignment, it can be a very useful step. The process of writing an annotation helps you learn more about your topic, develop a deeper understanding of the subject, and become better at evaluating various sources of information.

The following is an example of an APA format bibliography by the website EasyBib:

There are many online resources that demonstrate different formats of bibliographies, including the American Psychological Association website . Purdue University's Online Writing Lab also has examples of formatting an APA format bibliography.

Check out this video on their YouTube channel which provides detailed instructions on formatting an APA style bibliography in Microsoft Word.

You can check out the Purdue site for more information on writing an annotated APA bibliography as well.

What This Means For You

If you are taking a psychology class, you may be asked to create a bibliography as part of the research paper writing process. Even if your instructor does not expressly require a bibliography, creating one can be a helpful way to help structure your research and make the writing process more manageable.

For psychology majors , it can be helpful to save any bibliographies you have written throughout your studies so that you can refer back to them later when studying for exams or writing papers for other psychology courses.

What is a bibliography?

According to Infoplease.com, A bibliography is a list of the types of sources you used to get information for your report. It is included at the end of your report, on the last page (or last few pages).

What are the types of bibliography styles (MLA, APA, etc.)?

The 3 most common bibliography/citation styles are:

  • MLA Style: The Modern Language Association works cited page style
  • APA Style: The American Psychological Association style
  • Chicago Style: The bibliography style defined by the Chicago Manual of Style

We’ll give examples of how to create bibliography entries in various styles further down in this article. 

What sources do you put in a bibliography?

An annotated bibliography should include a reference list of any sources you use in writing a research paper. Any printed sources from which you use a text citation, including books, websites, newspaper articles, journal articles, academic writing, online sources (such as PDFs), and magazines should be included in a reference list. In some cases, you may need or want to cite conversations or interviews, works of art, visual works such as movies, television shows, or documentaries - these (and many others) can also be included in a reference list.

How to get started writing your bibliography

You will find it easier to prepare your MLA, APA, or Chicago annotated bibliography if you keep track of each book, encyclopedia, journal article, webpage or online source you use as you are reading and taking notes. Start a preliminary, or draft, bibliography by listing on a separate sheet of paper all your sources. Note down the full title, author’s last name, place of publication, web address, publisher, and date of publication for each source.

How To Write a Bibliography (Plus Printable Guide With Examples)

Give credit where credit is due.

Cover page plus several other pages from bibliography writing guide for students.

Writing a research paper involves a lot of work. Students need to consult a variety of sources to gather reliable information and ensure their points are well supported. Research papers include a bibliography, which can be a little tricky for students. Learn how to write a bibliography in multiple styles and find basic examples below.

Plus grab our printable Bibliography Guide for Students with examples from all three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . Just fill out the form on this page to get the free guide.

IMPORTANT: Each style guide has its own very specific rules, and they often conflict with one another. Additionally, each type of reference material has many possible formats, depending on a variety of factors. The overviews shown here are meant to guide students in writing basic bibliographies, but this information is by no means complete. Students should always refer directly to the preferred style guide to ensure they’re using the most up-to-date formats and styles.

What is a bibliography?

When you’re researching a paper, you’ll likely consult a wide variety of sources. You may quote some of these directly in your work, summarize some of the points they make, or simply use them to further the knowledge you need to write your paper. Since these ideas are not your own, it’s vital to give credit to the authors who originally wrote them. This list of sources, organized alphabetically, is called a bibliography.

A bibliography should include all the materials you consulted in your research, even if you don’t quote directly from them in your paper. These resources could include (but aren’t limited to):

  • Books and e-books
  • Periodicals like magazines or newspapers
  • Online articles or websites
  • Primary source documents like letters or official records

Bibliography vs. References

These two terms are sometimes used interchangeably, but they actually have different meanings. As noted above, a bibliography includes all the materials you used while researching your paper, whether or not you quote from them or refer to them directly in your writing.

A list of references only includes the materials you cite throughout your work. You might use direct quotes or summarize the information for the reader. Either way, you must ensure you give credit to the original author or document. This section can be titled “List of Works Cited” or simply “References.”

Your teacher may specify whether you should include a bibliography or a reference list. If they don’t, consider choosing a bibliography to show all the works you used in researching your paper. This can help the reader see that your points are well supported and allow them to do further reading on their own if they’re interested.

Bibliography vs. Citations

Citations refer to direct quotations from a text that are woven into your own writing. There are a variety of ways to write citations, including footnotes and endnotes. These are generally shorter than the entries in a reference list or bibliography. Learn more about writing citations here.

What does a bibliography entry include?

Depending on the reference material, bibliography entries include a variety of information intended to help a reader locate the material if they want to refer to it themselves. These entries are listed in alphabetical order and may include: ADVERTISEMENT

  • Author/s or creator/s
  • Publication date
  • Volume and issue numbers
  • Publisher and publication city
  • Website URL

These entries don’t generally need to include specific page numbers or locations within the work (except for print magazine or journal articles). That type of information is usually only needed in a footnote or endnote citation.

What are the different bibliography styles?

In most cases, writers use one of three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . There are many others as well, but these three are the most common choices for K–12 students.

Many teachers will state their preference for one style guide over another. If they don’t, you can choose your own preferred style. However, you should also use that guide for your entire paper, following their recommendations for punctuation, grammar, and more. This will ensure you are consistent throughout.

Below, you’ll learn how to write a simple bibliography using each of the three major style guides. We’ve included details for books and e-books, periodicals, and electronic sources like websites and videos. If the reference material type you need to include isn’t shown here, refer directly to the style guide you’re using.

APA Style Bibliography and Examples

Example of APA style bibliography entry.

Technically, APA style calls for a list of references instead of a bibliography. If your teacher requires you to use the APA style guide , you can limit your reference list to only items you cite throughout your work.

How To Write a Bibliography (References) Using APA Style

Here are some general notes on writing an APA reference list:

  • Title your bibliography section “References” and center the title on the top line of the page.
  • Do not center your references; they should be left-aligned. For longer items, subsequent lines should use a hanging indent of 1/2 inch.
  • Include all types of resources in the same list.
  • Alphabetize your list by author or creator, last name first.
  • Do not spell out the author/creator’s first or middle name—only use their initials.
  • If there are multiple authors/creators, use an ampersand (&) before the final author/creator.
  • Place the date in parentheses.
  • Capitalize only the first word of the title and subtitle, unless the word would otherwise be capitalized (proper names, etc.).
  • Italicize the titles of books, periodicals, and videos.
  • For websites, include the full site information, including the http:// or https:// at the beginning.

Books and E-Books APA Bibliography Examples

For books, APA reference list entries use this format (only include the publisher’s website for e-books):

Last Name, First Initial. Middle Initial. (Publication date). Title with only first word capitalized (unless there’s a proper name/noun) . Publisher. Publisher’s website

  • Wynn, S. (2020). City of London at war 1939–45 . Pen & Sword Military. https://www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical APA Bibliography Examples

For journal or magazine articles, use the following format. If you viewed the article online, include the URL at the end of the citation.

Last Name, First Initial. Middle Initial. (Publication date). Title of article. Magazine or Journal Title (Volume number) Issue number, page numbers. URL

  • Bell, A. (2009). Landscapes of fear: Wartime London, 1939–1945. Journal of British Studies (48) 1, 153–175. https://www.jstor.org/stable/25482966

Electronic APA Bibliography Examples

For articles with a specific author on a website, use this format:

Last Name, First Initial. Middle Initial. (Year, Month Date). Title . Site name. URL

  • Wukovits, J. (2023, January 30). A World War II survivor recalls the London Blitz . British Heritage . https://britishheritage.com/history/world-war-ii-survivor-london-blitz

When an online article doesn’t include a specific author or date, list it like this:

Title . (Year, Month Date). Site name. Retrieved Month Date, Year, from URL

  • Growing up in the Second World War . (n.d.). Imperial War Museums. Retrieved May 12, 2023, from https://www.iwm.org.uk/history/growing-up-in-the-second-world-war

When you need to list a YouTube video, use the name of the account that uploaded the video, and format it like this:

Name of Account. (Upload year, month day). Title [Video]. YouTube. URL

  • War Stories. (2023, January 15). How did London survive the Blitz during WW2? Cities at war: London [Video]. YouTube. https://youtu.be/uwY6JlCvbxc

MLA Style Bibliography Examples

Example of MLA style words cited entry.

MLA style calls for a Works Cited section, which includes all materials quoted or referred to in your paper. You may also include a Works Consulted section, including other reference sources you reviewed but didn’t directly cite. Together, these constitute a bibliography. If your teacher requests an MLA Style Guide bibliography, ask if you should include Works Consulted as well as Works Cited.

How To Write a Bibliography (Works Cited and Works Consulted) in MLA Style

For both MLA Works Cited and Works Consulted sections, use these general guidelines:

  • Start your Works Cited list on a new page. If you include a Works Consulted list, start that on its own new page after the Works Cited section.
  • Center the title (Works Cited or Works Consulted) in the middle of the line at the top of the page.
  • Align the start of each source to the left margin, and use a hanging indent (1/2 inch) for the following lines of each source.
  • Alphabetize your sources using the first word of the citation, usually the author’s last name.
  • Include the author’s full name as listed, last name first.
  • Capitalize titles using the standard MLA format.
  • Leave off the http:// or https:// at the beginning of a URL.

Books and E-Books MLA Bibliography Examples

For books, MLA reference list entries use the following format. Add the URL at the end for e-books.

Last Name, First Name Middle Name. Title . Publisher, Date. URL

  • Wynn, Stephen. City of London at War 1939–45 . Pen & Sword Military, 2020. www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical MLA Bibliography Examples

Here’s the MLA-style format for magazines, journals, and newspapers. For online articles, add the URL at the end of the listing:

For magazines and journals:

Last Name, First Name. “Title: Subtitle.” Name of Journal , volume number, issue number, Date of Publication, First Page Number–Last Page Number.

  • Bell, Amy. “Landscapes of Fear: Wartime London, 1939–1945.” Journal of British Studies , vol. 48, no. 1, January 2009, pp. 153–175. www.jstor.org/stable/25482966

When citing newspapers, include the page number/s for print editions or the URL for online articles:

Chicago Manual of Style Bibliography Examples

The Chicago Manual of Style (sometimes called “Turabian”) actually has two options for citing reference material: Notes and Bibliography and Author-Date. Regardless of which you use, you’ll need a complete detailed list of reference items at the end of your paper. The examples below demonstrate how to write that list.

How To Write a Bibliography Using The Chicago Manual of Style

Example of Chicago style bibliography entry.

Here are some general notes on writing a Chicago -style bibliography:

  • You may title it “Bibliography” or “References.” Center this title at the top of the page and add two blank lines before the first entry.
  • Left-align each entry, with a hanging half-inch indent for subsequent lines of each entry.
  • Single-space each entry, with a blank line between entries.
  • Include the “http://” or “https://” at the beginning of URLs.

Books and E-Books Chicago Manual of Style Bibliography Examples

For books, Chicago -style reference list entries use the following format. (For print books, leave off the information about how the book was accessed.)

Last Name, First Name Middle Name. Title . City of Publication: Publisher, Date. How e-book was accessed.

  • Wynn, Stephen. City of London at War 1939–45 . Yorkshire: Pen & Sword Military, 2020. Kindle edition.

Periodical Chicago Manual of Style Bibliography Examples

Here’s the style format for magazines, journals, and newspapers. For online articles, add the URL at the end of the listing.

For journal and magazine articles, use this format:

Last Name, First Name. Year of Publication. “Title: Subtitle.” Name of Journal , Volume Number, issue number, First Page Number–Last Page Number. URL.

Write an Annotated Bibliography

What is an annotated bibliography?

It is a list of citations for various books, articles, and other sources on a topic. 

An annotation is a short summary and/or critical evaluation of a source.

Annotated bibliographies answer the question: "What would be the most relevant, most useful, or most up-to-date sources for this topic?"

 Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself. 

Annotation versus abstracts 

An abstract is a paragraph at the beginning of the paper that discusses the main point of the original work. They typically do not include evaluation comments. 

Annotations can either be descriptive or evaluative. The annotated bibliography looks like a works cited page but includes an annotation after each source cited. 

Types of Annotations: 

Descriptive Annotations: Focuses on description. Describes the source by answering the following questions. 

Who wrote the document?

What does the document discuss?

When and where was the document written? 

Why was the document produced?

How was it provided to the public?

Evaluative Annotations: Focuses on description and evaluation. Includes a summary and critically assess the work for accuracy, relevance, and quality. 

Evaluative annotations help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project.

What does the annotation include?

Depending on your assignment and style guide, annotations may include some or all of the following information. 

  • Should be no more than 150 words or 4 to 6 sentences long. 
  • What is the main focus or purpose of the work?
  • Who is the intended audience?
  • ​How useful or relevant was the article to your topic?
  • Was there any unique features that useful to you?
  • What is the background and credibility of the author?
  • What are any conclusions or observations that your reached about the article?

Which citation style to use?

There are many styles manuals with specific instructions on how to format your annotated bibliography. This largely depends on what your instructor prefers or your subject discipline. Check out our citation guides for more information. 

Additional Information

Why doesn't APA have an official APA-approved format for annotated bibliographies?

Always consult your instructor about the format of an annotated bibliography for your class assignments. These guides provide you with examples of various styles for annotated bibliographies and they may not be in the format required by your instructor. 

Citation Examples and Annotations

Book Citation with Descriptive Annotation

Liroff, R. A., & G. G. Davis. (1981). Protecting open space: Land use control in the Adirondack Park. Cambridge, MA: Ballinger.

This book describes the implementation of regional planning and land use regulation in the Adirondack Park in upstate New York. The authors provide program evaluations of the Adirondack Park Agency’s regulatory and local planning assistance programs.

Journal Article Citation with Evaluative Annotation

Gottlieb, P. D. (1995). The “golden egg” as a natural resource: Toward a normative theory of growth management. Society and Natural Resources, 8, (5): 49-56.

This article explains the dilemma faced by North American suburbs, which demand both preservation of local amenities (to protect quality of life) and physical development (to expand the tax base). Growth management has been proposed as a policy solution to this dilemma. An analogy is made between this approach and resource economics. The author concludes that the growth management debate raises legitimate issues of sustainability and efficiency.

Book Citation

Lee, Seok-hoon, Yong-pil Kim, Nigel Hemmington, and Deok-kyun Yun. “Competitive Service Quality Improvement (CSQI): A Case Study in the Fast-Food Industry.” Food Service Technology 4 (2004): 75-84.

In this highly technical paper, three industrial engineering professors in Korea and one services management professor in the UK discuss the mathematical limitations of the popular SERVQUAL scales. Significantly, they also aim to measure service quality in the fast-food industry, a neglected area of study. Unfortunately, the paper’s sophisticated analytical methods make it inaccessible to all but the most expert of researchers.

Battle, Ken. “Child Poverty: The Evolution and Impact of Child Benefits.”  A Question of Commitment: Children's Rights in Canada . Ed. Katherine Covell and R.Brian Howe. Waterloo, ON: Wilfrid Laurier University Press. 2007. 21-44.

             Ken Battle draws on a close study of government documents, as well as his own research as an extensively-published policy analyst, to explain Canadian child benefit programs.  He outlines some fundamental assumptions supporting the belief that all society members should contribute to the upbringing of children.  His comparison of child poverty rates in a number of countries is a useful wake-up to anyone assuming Canadian society is doing a good job of protecting children.  Battle pays particular attention to the National Child Benefit (NCB), arguing that it did not deserve to be criticized by politicians and journalists.  He outlines the NCB’s development, costs, and benefits, and laments that the Conservative government scaled it back in favour of the inferior Universal Child Care Benefit (UCCB).  However, he relies too heavily on his own work; he is the sole or primary author of almost half the sources in his bibliography.  He could make this work stronger by drawing from others' perspectives and analyses.  However, Battle does offer a valuable source for this essay, because the chapter provides a concise overview of government-funded assistance currently available to parents.  This offers context for analyzing the scope and financial reality of child poverty in Canada.

Journal Article Example

  Kerr, Don and Roderic Beaujot. “Child Poverty and Family Structure in Canada, 1981-1997.”  Journal of Comparative Family Studies  34.3 (2003): 321-335.

             Sociology professors Kerr and Beaujot analyze the demographics of impoverished families.  Drawing on data from Canada’s annual Survey of Consumer Finances, the authors consider whether each family had one or two parents, the age of single parents, and the number of children in each household.  They analyze child poverty rates in light of both these demographic factors and larger economic issues.  Kerr and Beaujot use this data to argue that.

A Beginner’s Guide to Citations, References and Bibliography in Research Papers

a research paper bibliography

As an academician, terms such as citations, references and bibliography might be a part of almost every work-related conversation in your daily life. However, many researchers, especially during the early stages of their academic career, may find it hard to differentiate between citations, references and bibliography in research papers and often find it confusing to implement their usage. If you are amongst them, this article will provide you with some respite. Let us start by first understanding the individual terms better.

Citation in research papers:  A citation appears in the main text of the paper. It is a way of giving credit to the information that you have specifically mentioned in your research paper by leading the reader to the original source of information. You will need to use citation in research papers whenever you are using information to elaborate a particular concept in the paper, either in the introduction or discussion sections or as a way to support your research findings in the results section.

Reference in research papers:  A reference is a detailed description of the source of information that you want to give credit to via a citation. The references in research papers are usually in the form of a list at the end of the paper. The essential difference between citations and references is that citations lead a reader to the source of information, while references provide the reader with detailed information regarding that particular source.

Bibliography in research papers:

A bibliography in research paper is a list of sources that appears at the end of a research paper or an article, and contains information that may or may not be directly mentioned in the research paper. The difference between reference and bibliography in research is that an individual source in the list of references can be linked to an in-text citation, while an individual source in the bibliography may not necessarily be linked to an in-text citation.

It’s understandable how these terms may often be used interchangeably as they are serve the same purpose – namely to give intellectual and creative credit to an original idea that is elaborated in depth in a research paper. One of the easiest ways to understand when to use an in-text citation in research papers, is to check whether the information is an ongoing work of research or if it has been proven to be a ‘fact’ through reproducibility. If the information is a proven fact, you need not specifically add the original source to the list of references but can instead choose to mention it in your bibliography. For instance, if you use a statement such as “The effects of global warming and climate changes on the deterioration of environment have been described in depth”, you need not use an in-text citation, but can choose to mention key sources in the bibliography section. An example of a citation in a research paper would be if you intend to elaborate on the impact of climate change in a particular population and/or a specific geographical location. In this case, you will need to add an in-text citation and mention the correct source in the list of references.

a research paper bibliography

Citations References Bibliography
Purpose To lead a reader toward a source of information included in the text To elaborate on of a particular source of information cited in the research paper To provide a list of all relevant sources of information on the research topic

 

Placement In the main text At the end of the text; necessarily linked to an in-text citation At the end of the text; not necessarily linked to an in-text citation

 

Information Minimal; denoting only the essential components of the source, such as numbering, names of the first and last authors, etc.

 

Descriptive; gives complete details about a particular source that can be used to find and read the original paper if needed Descriptive; gives all the information regarding a particular source for those who want to refer to it

Now that you have understood the basic similarities and differences in these terms, you should also know that every journal follows a particular style and format for these elements. So when working out how to write citations and add references in research papers, be mindful of using the preferred style of your target journal before you submit your research document.

How do you format a bibliography in APA Style ® ?

a research paper bibliography

Go to 7th edition guidelines

APA Style ® calls for a list of references instead of a bibliography.

The requirements of a reference list are that all references cited in the text of a paper must be listed alphabetically by first author's last name in the list of references and that all references listed must be cited within the text.

A bibliography, however, typically includes resources in addition to those cited in the text and may include annotated descriptions of the items listed.

In general, the list of references is double-spaced and listed alphabetically by first author's last name. For each reference, the first line is typed flush with the left margin, and any additional lines are indented as a group a few spaces to the right of the left margin (this is called a hanging indent ).

For example:

APA Publications and Communications Board Working Group on Journal Article Reporting Standards. (2009). Reporting standards for research in psychology: Why do we need them? What might they be? American Psychologist, 63 , 839–851. doi:10.1037/0003-066X.63.9.839

Citation Styles Guide | Examples for All Major Styles

Published on June 24, 2022 by Jack Caulfield . Revised on November 7, 2022.

A citation style is a set of guidelines on how to cite sources in your academic writing . You always need a citation whenever you quote , paraphrase , or summarize a source to avoid plagiarism . How you present these citations depends on the style you follow. Scribbr’s citation generator can help!

Different styles are set by different universities, academic associations, and publishers, often published in an official handbook with in-depth instructions and examples.

There are many different citation styles, but they typically use one of three basic approaches: parenthetical citations , numerical citations, or note citations.

Parenthetical citations

  • Chicago (Turabian) author-date

CSE name-year

Numerical citations

CSE citation-name or citation-sequence

Note citations

  • Chicago (Turabian) notes and bibliography

Types of citation: parenthetical, note, numerical, which citation style should i use, parenthetical citation styles, numerical citation styles, note citation styles, frequently asked questions about citation styles.

The clearest identifying characteristic of any citation style is how the citations in the text are presented. There are three main approaches:

  • Parenthetical citations: You include identifying details of the source in parentheses in the text—usually the author’s last name and the publication date, plus a page number if relevant ( author-date ). Sometimes the publication date is omitted ( author-page ).
  • Numerical citations: You include a number in brackets or in superscript, which corresponds to an entry in your numbered reference list.
  • Note citations: You include a full citation in a footnote or endnote, which is indicated in the text with a superscript number or symbol.

Citation styles also differ in terms of how you format the reference list or bibliography entries themselves (e.g., capitalization, order of information, use of italics). And many style guides also provide guidance on more general issues like text formatting, punctuation, and numbers.

Prevent plagiarism. Run a free check.

In most cases, your university, department, or instructor will tell you which citation style you need to follow in your writing. If you’re not sure, it’s best to consult your institution’s guidelines or ask someone. If you’re submitting to a journal, they will usually require a specific style.

Sometimes, the choice of citation style may be left up to you. In those cases, you can base your decision on which citation styles are commonly used in your field. Try reading other articles from your discipline to see how they cite their sources, or consult the table below.

Discipline Typical citation style(s)
Economics
Engineering & IT
Humanities ; ;
Law ;
Medicine ; ;
Political science
Psychology
Sciences ; ; ; ;

The Bluebook: A Uniform System of Citation is the main style guide for legal citations in the US. It’s widely used in law, and also when legal materials need to be cited in other disciplines.

Bluebook footnote citation David E. Pozen, , 165, U. P🇦​​​​​. L. R🇪🇻​​​​​​​​​​. 1097, 1115 (2017).

Chicago notes and bibliography

Chicago notes and bibliography is one of the two citation styles presented in the Chicago Manual of Style (17th edition). It’s used mainly in the humanities.

Best, Jeremy. “Godly, International, and Independent: German Protestant Missionary Loyalties before World War I.” 47, no. 3 (September 2014): 585–611. https://doi.org/10.1017/S0008938914001654.

The Oxford University Standard for the Citation of Legal Authorities ( OSCOLA ) is the main legal citation style in the UK (similar to Bluebook for the US).

OSCOLA footnote citation 1. Chris Thornhill, ‘The Mutation of International Law in Contemporary Constitutions: Thinking Sociologically about Political Constitutionalism’ [2016] MLR 207.

There are many different citation styles used across different academic disciplines, but they fall into three basic approaches to citation:

  • Parenthetical citations : Including identifying details of the source in parentheses —usually the author’s last name and the publication date, plus a page number if available ( author-date ). The publication date is occasionally omitted ( author-page ).
  • Numerical citations: Including a number in brackets or superscript, corresponding to an entry in your numbered reference list.
  • Note citations: Including a full citation in a footnote or endnote , which is indicated in the text with a superscript number or symbol.

Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.

  • APA Style is the most popular citation style, widely used in the social and behavioral sciences.
  • MLA style is the second most popular, used mainly in the humanities.
  • Chicago notes and bibliography style is also popular in the humanities, especially history.
  • Chicago author-date style tends to be used in the sciences.

Other more specialized styles exist for certain fields, such as Bluebook and OSCOLA for law.

The most important thing is to choose one style and use it consistently throughout your text.

A scientific citation style is a system of source citation that is used in scientific disciplines. Some commonly used scientific citation styles are:

  • Chicago author-date , CSE , and Harvard , used across various sciences
  • ACS , used in chemistry
  • AMA , NLM , and Vancouver , used in medicine and related disciplines
  • AAA , APA , and ASA , commonly used in the social sciences

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

MLA Style  is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.

APA Format is the official writing style of the American Psychological Association, and is primarily used in subjects such as psychology, education, and the social sciences.

It specifies how to format academic papers and citations for publication in journals, periodicals, and bulletins.

This guide will show you how to prepare and format a document to be fully compliant with APA Format in 2020.

Before You Start Writing...

There are several steps you must take to prepare a new document for APA style before you start writing your paper:

  • Make sure the paper size is 8.5" x 11" (known as 'Letter' in most word processors).
  • Set the margin size to 1" on all sides (2.54cm).
  • Change the line spacing to double-spaced .
  • Add page numbers to the top-right corner of every page.
  • Add a running head to the top-left corner of every page.

We have a pre-made APA style template document you can download to be sure you are ready to start writing. You can download it below:

When your document is ready, proceed to writing the title page .

Annotated Bibliographies

What this handout is about.

This handout will explain why annotated bibliographies are useful for researchers, provide an explanation of what constitutes an annotation, describe various types of annotations and styles for writing them, and offer multiple examples of annotated bibliographies in the MLA, APA, and CBE/CSE styles of citation.

Introduction

Welcome to the wonderful world of annotated bibliographies! You’re probably already familiar with the need to provide bibliographies, reference pages, and works cited lists to credit your sources when you do a research paper. An annotated bibliography includes descriptions and explanations of your listed sources beyond the basic citation information you usually provide.

Why do an annotated bibliography?

One of the reasons behind citing sources and compiling a general bibliography is so that you can prove you have done some valid research to back up your argument and claims. Readers can refer to a citation in your bibliography and then go look up the material themselves. When inspired by your text or your argument, interested researchers can access your resources. They may wish to double check a claim or interpretation you’ve made, or they may simply wish to continue researching according to their interests. But think about it: even though a bibliography provides a list of research sources of all types that includes publishing information, how much does that really tell a researcher or reader about the sources themselves?

An annotated bibliography provides specific information about each source you have used. As a researcher, you have become an expert on your topic: you have the ability to explain the content of your sources, assess their usefulness, and share this information with others who may be less familiar with them. Think of your paper as part of a conversation with people interested in the same things you are; the annotated bibliography allows you to tell readers what to check out, what might be worth checking out in some situations, and what might not be worth spending the time on. It’s kind of like providing a list of good movies for your classmates to watch and then going over the list with them, telling them why this movie is better than that one or why one student in your class might like a particular movie better than another student would. You want to give your audience enough information to understand basically what the movies are about and to make an informed decision about where to spend their money based on their interests.

What does an annotated bibliography do?

A good annotated bibliography:

  • encourages you to think critically about the content of the works you are using, their place within a field of study, and their relation to your own research and ideas.
  • proves you have read and understand your sources.
  • establishes your work as a valid source and you as a competent researcher.
  • situates your study and topic in a continuing professional conversation.
  • provides a way for others to decide whether a source will be helpful to their research if they read it.
  • could help interested researchers determine whether they are interested in a topic by providing background information and an idea of the kind of work going on in a field.

What elements might an annotation include?

  • Bibliography according to the appropriate citation style (MLA, APA, CBE/CSE, etc.).
  • Explanation of main points and/or purpose of the work—basically, its thesis—which shows among other things that you have read and thoroughly understand the source.
  • Verification or critique of the authority or qualifications of the author.
  • Comments on the worth, effectiveness, and usefulness of the work in terms of both the topic being researched and/or your own research project.
  • The point of view or perspective from which the work was written. For instance, you may note whether the author seemed to have particular biases or was trying to reach a particular audience.
  • Relevant links to other work done in the area, like related sources, possibly including a comparison with some of those already on your list. You may want to establish connections to other aspects of the same argument or opposing views.

The first four elements above are usually a necessary part of the annotated bibliography. Points 5 and 6 may involve a little more analysis of the source, but you may include them in other kinds of annotations besides evaluative ones. Depending on the type of annotation you use, which this handout will address in the next section, there may be additional kinds of information that you will need to include.

For more extensive research papers (probably ten pages or more), you often see resource materials grouped into sub-headed sections based on content, but this probably will not be necessary for the kinds of assignments you’ll be working on. For longer papers, ask your instructor about their preferences concerning annotated bibliographies.

Did you know that annotations have categories and styles?

Decisions, decisions.

As you go through this handout, you’ll see that, before you start, you’ll need to make several decisions about your annotations: citation format, type of annotation, and writing style for the annotation.

First of all, you’ll need to decide which kind of citation format is appropriate to the paper and its sources, for instance, MLA or APA. This may influence the format of the annotations and bibliography. Typically, bibliographies should be double-spaced and use normal margins (you may want to check with your instructor, since they may have a different style they want you to follow).

MLA (Modern Language Association)

See the UNC Libraries citation tutorial for basic MLA bibliography formatting and rules.

  • MLA documentation is generally used for disciplines in the humanities, such as English, languages, film, and cultural studies or other theoretical studies. These annotations are often summary or analytical annotations.
  • Title your annotated bibliography “Annotated Bibliography” or “Annotated List of Works Cited.”
  • Following MLA format, use a hanging indent for your bibliographic information. This means the first line is not indented and all the other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
  • Begin your annotation immediately after the bibliographic information of the source ends; don’t skip a line down unless you have been told to do so by your instructor.

APA (American Psychological Association)

See the UNC Libraries citation tutorial for basic APA bibliography formatting and rules.

  • Natural and social sciences, such as psychology, nursing, sociology, and social work, use APA documentation. It is also used in economics, business, and criminology. These annotations are often succinct summaries.
  • Annotated bibliographies for APA format do not require a special title. Use the usual “References” designation.
  • Like MLA, APA uses a hanging indent: the first line is set flush with the left margin, and all other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
  • After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line.
  • The entire annotation is indented an additional two spaces, so that means each of its lines will be six spaces from the margin (if your instructor has said that it’s okay to tab over instead of using the four spaces rule, indent the annotation two more spaces in from that point).

CBE (Council of Biology Editors)/CSE (Council of Science Editors)

See the UNC Libraries citation tutorial for basic CBE/CSE bibliography formatting and rules.

  • CBE/CSE documentation is used by the plant sciences, zoology, microbiology, and many of the medical sciences.
  • Annotated bibliographies for CBE/CSE format do not require a special title. Use the usual “References,” “Cited References,” or “Literature Cited,” and set it flush with the left margin.
  • Bibliographies for CSE in general are in a slightly smaller font than the rest of the paper.
  • When using the name-year system, as in MLA and APA, the first line of each entry is set flush with the left margin, and all subsequent lines, including the annotation, are indented three or four spaces.
  • When using the citation-sequence method, each entry begins two spaces after the number, and every line, including the annotation, will be indented to match the beginning of the entry, or may be slightly further indented, as in the case of journals.
  • After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line. The entire annotation follows the indentation of the bibliographic entry, whether it’s N-Y or C-S format.
  • Annotations in CBE/CSE are generally a smaller font size than the rest of the bibliographic information.

After choosing a documentation format, you’ll choose from a variety of annotation categories presented in the following section. Each type of annotation highlights a particular approach to presenting a source to a reader. For instance, an annotation could provide a summary of the source only, or it could also provide some additional evaluation of that material.

In addition to making choices related to the content of the annotation, you’ll also need to choose a style of writing—for instance, telescopic versus paragraph form. Your writing style isn’t dictated by the content of your annotation. Writing style simply refers to the way you’ve chosen to convey written information. A discussion of writing style follows the section on annotation types.

Types of annotations

As you now know, one annotation does not fit all purposes! There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Your assignments will usually make it clear which citation format you need to use, but they may not always specify which type of annotation to employ. In that case, you’ll either need to pick your instructor’s brain a little to see what they want or use clue words from the assignment itself to make a decision. For instance, the assignment may tell you that your annotative bibliography should give evidence proving an analytical understanding of the sources you’ve used. The word analytical clues you in to the idea that you must evaluate the sources you’re working with and provide some kind of critique.

Summary annotations

There are two kinds of summarizing annotations, informative and indicative.

Summarizing annotations in general have a couple of defining features:

  • They sum up the content of the source, as a book report might.
  • They give an overview of the arguments and proofs/evidence addressed in the work and note the resulting conclusion.
  • They do not judge the work they are discussing. Leave that to the critical/evaluative annotations.
  • When appropriate, they describe the author’s methodology or approach to material. For instance, you might mention if the source is an ethnography or if the author employs a particular kind of theory.

Informative annotation

Informative annotations sometimes read like straight summaries of the source material, but they often spend a little more time summarizing relevant information about the author or the work itself.

Indicative annotation

Indicative annotation is the second type of summary annotation, but it does not attempt to include actual information from the argument itself. Instead, it gives general information about what kinds of questions or issues are addressed by the work. This sometimes includes the use of chapter titles.

Critical/evaluative

Evaluative annotations don’t just summarize. In addition to tackling the points addressed in summary annotations, evaluative annotations:

  • evaluate the source or author critically (biases, lack of evidence, objective, etc.).
  • show how the work may or may not be useful for a particular field of study or audience.
  • explain how researching this material assisted your own project.

Combination

An annotated bibliography may combine elements of all the types. In fact, most of them fall into this category: a little summarizing and describing, a little evaluation.

Writing style

Ok, next! So what does it mean to use different writing styles as opposed to different kinds of content? Content is what belongs in the annotation, and style is the way you write it up. First, choose which content type you need to compose, and then choose the style you’re going to use to write it

This kind of annotated bibliography is a study in succinctness. It uses a minimalist treatment of both information and sentence structure, without sacrificing clarity. Warning: this kind of writing can be harder than you might think.

Don’t skimp on this kind of annotated bibliography. If your instructor has asked for paragraph form, it likely means that you’ll need to include several elements in the annotation, or that they expect a more in-depth description or evaluation, for instance. Make sure to provide a full paragraph of discussion for each work.

As you can see now, bibliographies and annotations are really a series of organized steps. They require meticulous attention, but in the end, you’ve got an entire testimony to all the research and work you’ve done. At the end of this handout you’ll find examples of informative, indicative, evaluative, combination, telescopic, and paragraph annotated bibliography entries in MLA, APA, and CBE formats. Use these examples as your guide to creating an annotated bibliography that makes you look like the expert you are!
