There are many different types of references (e.g. books, journal articles, websites). Click on the type you require below to see the components of the reference with an example.

• Journal Articles
• Web pages and social media
• Newspaper articles

Dictionary or Encyclopaedia

Thesis or dissertation.

• Reports and Datasets
• Conferences
• Images, figures and tables

Exhibitions

• Audiovisual and Digital Media
• Lecture Notes and Presentations

• Author/Editor (Surname, Initials) ,
• (Year of publication).
• Title (in italics) .
• Edition (other than first edition) .

An e-book retrieved from an academic database that does not have a DOI (Digital Object Identifier) is referenced as though it were the print version, as above. (A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works).

Books with a URL or a DOI can be referenced like this:

• Author/editor (Surname, Initials)

(Year of publication)

• Title of book (in italics)
• (Edition) (if not the 1st edition)

Book Chapter

• Author of chapter/section (Surname, Initials)
• Title of chapter/section.
• ‘In:’ followed by author/editor of book, (in direct order)
• Title of book (in italics) .
• (Page reference).

Journal article (print)

• Author(s) (Surname, Initials)
• Title of article

Title of journal (in italics, first letter of each word should be capitalised, except for words such as and, of, the)        

Issue information (volume, issue, pages) (volume in italics)

Journal article (online)

• Title of article.
• Title of journal (in italics, first letter of each word should be capitalised, except for words such as and, of, the)
• Issue information (date, volume, issue no., pages) (volume in italics)

Journal article (database without DOI)

Journal articles retrieved from databases without a DOI can be referenced like a print journal, as above.

Journal article (with DOI)

• Issue information (date, volume , issue no., pages) (volume in italics)

Journal article (21 or more authors)

List the first nineteen authors followed by three spaced ellipsis points (...) and then the last author's name.

Journal article (pre-publication)

“Pre-print”, “In press” and “advanced online publication” usually refer to articles that have been accepted for publication, but may not yet have been assigned to a publication volume/issue. These articles can be cited using the year of online publication and the DOI.

• Issue information (date, volume, issue no., pages) (if any available)
• Advance online publication.

arXiv is a collection facility for scientific 'e-prints'. Some of them have been published and some have not. APA recommends updating your references when you're close to finishing your assignment. If you've cited a preprint that has since been published, cite the published journal article.

In the example below, you will see that the title is in italics. This is because it hasn't yet been accepted in a journal and is, therefore, considered a stand-alone work.

Journal Article (with article numbers, not page numbers)

If the journal article has an article number instead of a page range, include the word “Article” and then the article number instead of the page range.

• Journal Title  (in italics)
• Volume ,  (in italics)
• Article number 

Magazine Article

• (Year of publication, Month day)
• Title of magazine (in italics, first letter of each word should be capitalised, except for words such as and, of, the)

Wikipedia is a free online encyclopaedia, created and edited by volunteers around the world. It is not a scholarly source, so your lecturer may not be happy for you to use it as a source in your assignments. Scholarly assignments should generally rely on peer-reviewed and other scholarly work vetted by experts in the field. However, it may be a good starting point for you in your research to find citations to original source materials that you do want to use.

Wikipedia is a constantly changing site, so cite an archived version of the page, if you can (select 'view history' and then the date of the version you used). If it doesn't have a permanent link to an archived version of the page, include a URL for the entry and the retrieval date.

Images, illustrations, photos (print)

If you are citing an illustration, figure, diagram or table, start with the source in which it appeared. For example, i f you are referencing an image printed in a book, you first mention the image in-text, indicating the name and creator of the image, and the book in which it can be found, along with the page details.  The reference list entry will be for the whole article or book.

In-text citation:

Reference List:

In the reference list, you list the book in which the image is found:

When you include an image or photo in your text, as well as citing the source, you will also need to include a caption and list it in a Table of Figures ( click here for more information ). Images you created yourself don't have to be cited, but should still be included in the list of figures.

Image, illustration, photo or table (online)

• Creator  (Surname, initial(s))
• [Internet handle] (if appropriate)

• URL (if viewed online)

It can often be hard to find accurate information about images accessed online.  However, if you do need to cite an image with no author, date or title listed, there are ways around this.  For untitled images, include a description of the image, in square brackets, where the title would usually go. If there is no publication date, add “n.d.” in place of the date, and add the date that you accessed the image.

• Curator(s) (Surname, Initial(s)) .
• (Year or years ran).

What is citing?

Citing is identifying the sources you have used in the text of your assignment.  This may be done as;

a direct quotation

paraphrasing

summarising

In-text citations give brief details about the source that you refer to.

This is an example citation (Harvard referencing style):

(Pears and Shields, 2013)  

Further citation examples from the different referencing styles used at Aberystwyth University can be found here .

The citations will allow the person reading your assignment to locate the full details of the source you have used in the reference list located at the end of your work.

Reference list (Harvard Style)

How to use quotes in your assignment.

When you use quotations they should be relevant.  Try not to use too many as they can break the flow of your text.  You will need to balance quotations with your own understanding of the sources used.

Don't forget - quotes are included in your word count!

A few tips:

Enclose any quotes in " quotation marks " - be consistent. Check out the further examples to see whether your chosen referencing style uses single or double quotation marks.

If using long quotes that are more than a few sentences, add these as a separate paragraph. This should be indented and there is no need to use quotation marks. ( Please note : The Department of Geography and Earth Sciences stipulate that long, indented quotations require quotation mark at the beginning and the end of the quotation).

Depending on the referencing style you are using, give the author, date and page number that the quote is from.

The full details of the source of the quote are then added into the reference list at the end of your assignment.

Example (Harvard Style):

In-text citation

'There are several ways in which you can incorporate citations into your text, depending on your own style and the flow of the work' (Pears and Shields, 2013, p. 8).

Reference list

How to paraphrase.

Paraphrasing involves expressing another author’s ideas or arguments in your own words, without direct quotation but with due acknowledgement.  It entails reformulating key points or information accurately, so that nothing important is lost but the means of communication is new. For instance:

Quotation     ‘It is impossible to step twice into the same river’ (Heraclitus) Paraphrase     Heraclitus argues that, just as a river is always in motion, the world is always changing so that nothing stays the same.

Paraphrasing can help with the flow or continuity of your written work and is a good way of demonstrating your understanding.

Read your source a few times to ensure you understand the meaning

Restate the key point(s) from the source in your own words, but without distorting the original meaning

Ensure you cite and reference the source.

Please note: When paraphrasing, you should NOT copy a passage from your source and then seek to change some of its wording. Use your own words and phrases from beginning to end when paraphrasing.

How to summarise.

This method provides the key points from an article, book or web page as a brief statement.

A few Tips;

Summaries should be your own work. It is NOT permitted to use online summary tools or other software for this purpose.

Ensure you cite and reference the source

Only list the main topics

In text citation

Importantly, one particular book (Pears and Shields, 2013) looks at the different citation methods when including them in an assignment.

APA 7th edition

What is apa style.

APA style  is a referencing method developed by the American Psychological Association and is a version of the commonly used  Author-Date system . 

This guide is based on the official APA website and the following text:

American Psychological Association. (2020).  Publication manual of the American Psychological Association  (7th ed.).  https://doi.org/10.1037/0000165-000

Which style does my School use? 

Some Schools or individual units require a different style from the one outlined here. Always use the citation style required by your lecturer. If in doubt, check your unit outline, in MyLO, or ask your lecturer or tutor.

• How to cite
• Multiple authors and works
• Direct quotes

In-text citations direct the reader to the Reference List to view the full details of the source.

When paraphrasing, In-text citations can be included as:

1. Parenthetical citations - by inserting the author and date in parentheses, usually at the end of a sentence, e.g....opportunity and economy are two factors that may have influenced changes in parental roles (Bomar, 2004).

2. Narrative citations - by incorporating the name of the author, followed by the date enclose in parentheses into the text of the paper, e.g. Sternberg (1993) suggests results should be carefully analysed...

• In-text citations guide, from APA Guidelines to help writers determine the appropriate level of citation and how to avoid plagiarism and self-plagiarism
• In-text citations checklist, from APA

Multiple authors

Multiple works

When citing multiple works in parentheses, arrange the citations in alphabetical order and separate them with semicolons, e.g.

(Citizen, 2019; Jones, 1999; Smith, 2001)

Multiple works can be arranged in any order when they are incorporated into the text of the paper (narrative citation).

• Page numbers are always included for direct quotations e.g. (Hiebert, 2009, p. 69).
• When the quote is 40 words or less d irect quotations should be placed within the text and surrounded by double quotation marks, e.g.  "we cannot possibly know and understand the culture of every individual and community we might encounter throughout the course of our careers" (Mkandawire-Valhmu, 2018, p. 24).
• When the quote is more than 40 words, direct quotations should be started on a new line and indented from the left margin, without quotation marks, e.g.

In an era of globalization, a healthcare provider needs to be prepared for encounters for people of diverse backgrounds and experiences. The culturally safe healthcare provider needs to have a deep understanding of where people have been and what they have experienced in their countries of origin. (Mkandawire-Valhmu, 2018, p. 73)

• Quotations More details from APA on how to include direct quotes in text

Reference Lists

A reference list is placed at the end of your paper. It contains the full details of all the references cited in the text of your paper. These details should be sufficient for the reader to be able to identify and locate the sources. 

• Elements of reference list entries APA provides detailed guidelines on each element of a reference.

Table of contents

Edition or volume of a book, edited or translated book, book chapter, dictionary or encyclopedia, frequently asked questions about harvard referencing.

If the book you’re citing is a second or later edition (i.e. when the edition is stated on the title page or cover), specify this in your reference. Abbreviate ‘edition’ to ‘edn’ or ‘revised edition’ to ‘rev ed’.

When referencing a book published in multiple volumes, include the total number of volumes in your reference.

If you’re just referencing one volume, omit the total number but include the number and subtitle of the particular volume you’re referencing as part of the title.

If a book specifies an editor and/or translator, this information should be included in the reference.

When a book has an editor in addition to the main author, the editor’s name is included later in the reference.

When the editor is the main author (i.e. when it’s their name on the cover), their name comes first. Use “ed.” for a single editor and “eds.” if there are multiple editors.

If you use a specific chapter or work from an edited collection, follow the format for referencing a book chapter instead.

When you reference a book that has been translated from another language, include the original language and the translator’s name.

Unlike other names, the translator’s name is not inverted: the initial comes first.

If a book contains chapters or works by various different authors, such as a collection of essays or an anthology of short stories, reference the specific chapter or work, followed by details of the book.

The chapter title appears in quotation marks, while the book title is italicized. At the end of the reference, specify the page range on which the chapter appears.

If a book is entirely written by one author, always reference the whole book, even if you only discuss one chapter.

Dictionaries, encyclopedias, and other reference works very often don’t list specific authors. In these cases, they are cited and referenced using their titles in the author position:

Where a reference work does have an author, it can be referenced like a normal book. Where different sections of a reference work are attributed to different authors, they can be referenced like chapters in an edited book.

Prevent plagiarism, run a free check.

When an ebook is presented like a printed book, with page numbers and publication details included, you can reference it in the same format as you would the print version.

Otherwise, the ebook format differs slightly: I nclude a link to where you found or purchased it online instead of publisher information. This link is generally just to the store or database you used, not the specific book.

In addition, in-text citations will have to use something other than page numbers when necessary, such as a percentage or location number. Use whatever marker is available on your device.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard style , when you quote directly from a source that includes page numbers, your in-text citation must include a page number. For example: (Smith, 2014, p. 33).

You can also include page numbers to point the reader towards a passage that you paraphrased . If you refer to the general ideas or findings of the source as a whole, you don’t need to include a page number.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

In Harvard style referencing , to distinguish between two sources by the same author that were published in the same year, you add a different letter after the year for each source:

• (Smith, 2019a)
• (Smith, 2019b)

Add ‘a’ to the first one you cite, ‘b’ to the second, and so on. Do the same in your bibliography or reference list .

• APA Style Examples: References and Citations Comprehensive list of source types with sample references and citations.

When you use someone else's words or ideas in an assignment, you must cite them. By citing them, you are acknowledging that the words/ideas are not your own.

This will make it clear to your instructor what ideas are your own, and what ideas belong to someone else.

It's perfectly okay to use someone else's ideas, as long as you cite them!

There are TWO elements to a citation:

In-text citation : These appear in your paper, and indicate to your reader that the information immediately preceding the citation came from another source.

References : This is the list of sources at the end of your paper that list all of the sources you used in your assignment.

A citation is not complete unless both elements -- an in-text citation, and corresponding References entry -- are present.

Note : You only have to cite sources that you used in your assignment. If you read an article and it was helpful, but you did not use it in your assignment, do not include it in your References.

Your References entry will depend on the source you used -- for example, a book, article, etc. Consult the examples in the left side menu of the Guide to see specific examples for your References entries.

If there is only one entry in your References list, the heading is: Reference

Note: Do not change the order of the authors' names for the sources you list in your References! The order of the authors' names is selected by the authors.

1 Author List the author in your References.

2 Authors For sources with 2 authors, list both authors connected with an ampersand.

3-19 Authors

List all of the authors and connect the second-last author and last author with an ampersand.

20+ Authors

List the first 19 authors, then include an ellipsis to represent additional authors’ names, followed by the final author’s name.

When you quote from other sources in your paper, you can use a Direct Quote (take the author's words exactly) or Paraphrase (when you take the author's ideas and put them in your own words).

Direct Quote example

If the quote extends across multiple pages:

No Page Numbers If no page number is available (as is the case with websites), include the paragraph number.

If there are many paragraphs that are too difficult to count, add a section/heading (if available).

If the quote extends across multiple paragraphs:

Abbreviated Authors Include the full name in the first mention of the text, then include the abbreviation.

If the group name first appears in an in-text citation, include the abbreviation in square brackets:

Paraphrase example Do not include quotation marks if you are paraphrasing.

2 Authors For sources with 1-2 authors, list the last names of both authors in your in-text citation:

3 or More Authors For sources with 3 or more authors, list the first author only and replace the remaining authors with "et al.":

The date of publication must be included in your in-text citations and References. 

Which Date Should You Use?

The date may be the year, the year and month, or the year month and day (it will depend on what kind of source you are citing). The examples on this guide will indicate what form of date should be entered for the resource you are citing.

For books : use the copyright date shown on the copyright page.

For journal articles : use year of the volume (even if it is different than the copyright year).

For websites and webpages , use the date that applies to the content you are citing. Do not use the copyright date from the website footer as this date may not apply to the content you are citing. Use the "last updated" date for a webpage if it applies to the content you are citing. If there is no separate date for the work you are citing on the webpage, treat the work as having no date and enter "n.d." in the date field. 

In-Text Citation

For more information on dates, please consult the APA Manual, 7th edition , page 289.

You may cite more than one source in an in-text citation.

List the sources alphabetically by the author's last name and separate the citations with a semicolon.

The language in which the student's paper is written is considered the "main language" and any other language in the paper would be considered "another language".

To cite a work that's in another language, the student should cite the source in the original language, but also translate the title only (in square brackets) for the reader. The translation does not have to be a literal translation.

When a corporate entity is the author of a source, use the corporate name.

Public Health Agency of Canada. (2012). Curbing childhood obesity: A federal, provincial and territorial framework for action to promote healthy weights. http://www.phac-aspc.gc.ca/hp-ps/hl-mvs/framework-cadre/pdf/ccofw-eng.pdf

There may come a time when you have multiple sources that are published by the same author and in the same year. 

In these cases, you will add a References entry for each source. Assign lower case letters in the date field to distinguish them, starting with a. The letters are assigned alphabetically, by title.

Public Health Agency of Canada. (2012a).  Biosafety and biosecurity. https://www.canada.ca/en/services/health/biosafety-biosecurity.pdf

Public Health Agency of Canada. (2012b).  Food safety. https://www.canada.ca/en/public-health/services/food-safety.pdf

Include the letters in your in-text citation:

Quotations longer than 40 words are formatted as block quotations:

• Start on a new line
• Omit double quotation marks
• Indent the entire quotation about half an inch from the left margin
• Double space the entire quote
• Place citation after the final punctuation mark in the quotation

The following information pertains to block quotes:

This is a block quotation, longer than 40 words. Notice how there are no quotation marks and the entire quote is double-spaced and indented from the left margin. The citation comes after the closing punctuation. (Jones & Smith, 2010, p. 121)

According to the APA Manual, 7th edition, "self-plagiarism is the presentation of your own previously published work as original."

If you do wish to use work you completed for a previous assignment in a new assignment, please discuss it with your instructor first.

There may come a time when you are required to use information from a previous assignment in a new assignment.

The APA Manual advises to place all of your duplicated work together, when possible (in a single paragraph or a few paragraphs), and include a citation. It's also recommended that you introduce the duplicated work with a phrase such as, "as I have previously discussed". Do not use quotation marks around your own material.

Cite your previous work as an "unpublished work":

In-text citations are brief references in the running text that direct readers to the reference entry at the end of the paper. You include them every time you quote or paraphrase someone else’s ideas or words to avoid plagiarism . Our plagiarism checker  can help ensure your paper contains appropriate author attributions.

An APA in-text citation consists of the author’s last name and the year of publication (also known as the author-date system). If you’re citing a specific part of a source, you should also include a locator such as a page number or timestamp. For example: (Smith, 2020, p. 170) .

Parenthetical vs. narrative citation

The in-text citation can take two forms: parenthetical and narrative. Both types are generated automatically when citing a source with Scribbr’s APA Citation Generator.

• Parenthetical citation: According to new research … (Smith, 2020) .
• Narrative citation: Smith (2020) notes that …

Multiple authors and corporate authors

The in-text citation changes slightly when a source has multiple authors or an organization as an author. Pay attention to punctuation and the use of the ampersand (&) symbol.

Missing information

When the author, publication date or locator is unknown, take the steps outlined below.

Are your APA in-text citations flawless?

The AI-powered APA Citation Checker points out every error, tells you exactly what’s wrong, and explains how to fix it. Say goodbye to losing marks on your assignment!

Get started!

APA references generally include information about the author , publication date , title , and source . Depending on the type of source, you may have to include extra information that helps your reader locate the source.

Reference examples

Citing a source starts with choosing the correct reference format. Use Scribbr’s Citation Example Generator to learn more about the format for the most common source types. Pay close attention to punctuation, capitalization, and italicization.

Generate APA citations for free

It is not uncommon for certain information to be unknown or missing, especially with sources found online. In these cases, the reference is slightly adjusted.

On the first line of the page, write the section label “References” (in bold and centered). On the second line, start listing your references in alphabetical order .

Apply these formatting guidelines to the APA reference page:

• Double spacing (within and between references)
• Hanging indent of ½ inch
• Legible font (e.g. Times New Roman 12 or Arial 11)
• Page number in the top right header

Which sources to include

On the reference page, you only include sources that you have cited in the text (with an in-text citation ). You should not include references to personal communications that your reader can’t access (e.g. emails, phone conversations or private online material).

Prevent plagiarism. Run a free check.

When no individual author name is listed, but the source can clearly be attributed to a specific organization—e.g., a press release by a charity, a report by an agency, or a page from a company’s website—use the organization’s name as the author in the reference entry and APA in-text citations .

When no author at all can be determined—e.g. a collaboratively edited wiki or an online article published anonymously—use the title in place of the author. In the in-text citation, put the title in quotation marks if it appears in plain text in the reference list, and in italics if it appears in italics in the reference list. Shorten it if necessary.

When you quote or paraphrase a specific passage from a source, you need to indicate the location of the passage in your APA in-text citation . If there are no page numbers (e.g. when citing a website ) but the text is long, you can instead use section headings, paragraph numbers, or a combination of the two:

(Caulfield, 2019, Linking section, para. 1).

Section headings can be shortened if necessary. Kindle location numbers should not be used in ebook citations , as they are unreliable.

If you are referring to the source as a whole, it’s not necessary to include a page number or other marker.

The abbreviation “ et al. ” (meaning “and others”) is used to shorten APA in-text citations with three or more authors . Here’s how it works:

Only include the first author’s last name, followed by “et al.”, a comma and the year of publication, for example (Taylor et al., 2018).

APA Style usually does not require an access date. You never need to include one when citing journal articles , e-books , or other stable online sources.

However, if you are citing a website or online article that’s designed to change over time, it’s a good idea to include an access date. In this case, write it in the following format at the end of the reference: Retrieved October 19, 2020, from https://www.uva.nl/en/about-the-uva/about-the-university/about-the-university.html

"I thought AI Proofreading was useless but.."

I've been using Scribbr for years now and I know it's a service that won't disappoint. It does a good job spotting mistakes”

References provide the information necessary for readers to identify and retrieve each work cited in the text .

Check each reference carefully against the original publication to ensure information is accurate and complete. Accurately prepared references help establish your credibility as a careful researcher and writer.

Consistency in reference formatting allows readers to focus on the content of your reference list, discerning both the types of works you consulted and the important reference elements (who, when, what, and where) with ease. When you present each reference in a consistent fashion, readers do not need to spend time determining how you organized the information. And when searching the literature yourself, you also save time and effort when reading reference lists in the works of others that are written in APA Style.
