Home » Essay guidelines » How to cite sources in APA
APA (American Psychological Association) style is a very popular academic writing style commonly used in social sciences.
It is essential to properly cite the sources you used in your paper to avoid plagiarism. There are some basic guidelines and rules that you should follow, and we are here to help you with them.
The citation guide we offer in this article is based on the latest APA version: The 7th edition of the APA Publication Manual (2020).
There are four essential components to APA Format citation:
- Author, Date, Title, Source
In this guideline, you’ll find out how to correctly place these components in your APA format citations. First, let’s find out how to do in-text citations and then move on to the essential components of APA format.
How to do in-text citations
In-text citations are a must in APA Style after using a quote or paraphrase from another person’s work. Basically, you must give a reference every time you paraphrase or quote another person’s ideas in your academic essay.
- APA in-text citations must contain the author’s last name and the year of publication inside a parenthesis. For example: (Johnson, 2021).
- When citing a particular part of a source, it is important to add a page number (if the source is written) and/or a timestamp (if the source is audiovisual). For example: (Johnson, 2021, p. 37).
There are two different forms of in-text citations:
- Parenthetical citation: Arguments regarding the issue… (Johnson, 2021).
- Narrative citation: Johnson (2021) argues that…
Citing two authors
When in-text citing works with two authors, do the following for parenthetical citation:
- Arguments regarding the issue… (Johnson & Williams, 2021).
- Johnson and Williams (2021) argue that…
Citing three or more authors
- Arguments regarding the issue… (Johnson et al., 2021).
- Johnson et al. (2021) argue that…
Citing an unknown author
When in-text citing a work of an unknown author, use the source title. For example: (“How to Cite Sources in APA Format,” 2021).
- Your in-text citation should be in quotation marks if the work you are citing is an article, web page, or chapter.
- Your in-text citation should be italicized if it is a title (see choosing good titles) of a book or a report.
Citing organizations as authors
If the work you are citing has an organization as an author, write the full name of the organization. Note that if the organization has an abbreviation, you should also add it to your in-text citation.
- For example: United Nations (2021), … OR (United Nations [UN], 2021)
You can only use the abbreviation of your source after your first citation. However, note that if there is another organization with the same abbreviation, do not use only the abbreviation as it can cause ambiguity.
Citing indirect sources
You should always try to find the primary source and cite it during the writing process. However, in case you fail to access the primary source, use the phrase “as cited in.”
Parenthetical citation
Arguments regarding the issue… (Garcia, 2019, as cited in Johnson, 2021).Narrative citation
Garcia (as cited in Johnson, 2021) argues that…Do not forget to identify the primary source in your citation.
Citing usernames
In case the author’s name is a username such as a Twitter handle, include the username while maintaining the @ symbol. Furthermore, if you know the real name of the owner, provide the real name and then add the username in brackets.
For example:
- @Jacksepticeye
- Winfrey, Oprah [@Oprah].
Citing different author roles
In case contributors have additional roles other than “author,” add a description of their additional roles in parentheses. After providing the author’s last name and their description as an author (A. A.), simply add:
- (Ed.) abbreviation for editor
- (Director) for a movie director
- (Executive producer) for an executive producer of a tv series
Citing electronic sources
As electronic sources have started replacing printed sources each day, it is essential to know how to in-text cite electronic sources in the 7th edition of APA.
You should cite electronic sources the way you would other sources if the author and date are provided. Follow these instructions for in-text citing web pages:
- Web page with author: … (Last name, 2021).
- Web page with organizational author: … (Title of the page, 2021).
- Web page with no date: … (Title of the page, n.d).
- Web page without page numbers: If a web page doesn’t have page numbers, try to add information to help your reader find the part that is cited. You can add the section that the citation is taken and/or provide the reader with the paragraph number (para. 27). For example: According to Johnson (2021), … (Internet Speed in Third World Countries section, para. 7).
Writing the dates
If you’ve understood how to deal with the author(s) in your APA citation, let’s move on to the second part: Dates!
The date should come after the author in your citation, and it means different things for different works.
- For books, take the copyright date.
- For journals, find the publication date of volume and add it to your citation.
- For web pages, find out when the page was last updated and use it.
-
What is a retrieval date and when to use it?
A retrieval date marks the date that you found out the information. It should be included in your citation after the title and before the URL.
- -Webster. (n.d.). Occam's razor. In Merriam-Webster.com dictionary. Retrieved July 14, 2021, from merriam -webster.com/ dictionary/Occam%27s%20razor
You can use the retrieval date in your citation if the information you found may change over time.
-
Unknown publication dates
In case you don’t have access to the publication date, write “n.d” (no date) for the publication date. See Abbreviations in the APA Style section for more information on abbreviations.
-
Multiple works by the same author in the same year
In case you are unfortunate enough to deal with this complication, use lower-case letters (see capitalization rules and heading rules) to differentiate between the two works. To do so, just assign the works with different letters (a, b, c) in the order they are listed in your Reference List.
- Johnson, B. (2021a) Internet Speeds Around the World. …
- Johnson, B. (2021b) Technological Advancements in Developing Countries. …
To assign letters in both your reference list and in-text citations, you should order the works by their titles without regarding “A,” “An,” and “The.”
Writing the titles
There is an important factor when writing titles: Determine whether your source is a work that is a part of a whole or not.
If it is part of a whole:
- Write the title with no style.
- Add the title of the whole italicized.
-
Example
Bradley, C. (2021). Into the Tone World: Little Huey Creative Music Orchestra. In Universal Tonality: The Life and Music of William Parker (pp. 194–215). Duke University Press.
Pro tip
If the page numbers are not provided, add the "." after the title of the whole. However, if it is provided, add it after the page numbers.When to use brackets
When you need to identify your source, describe it in brackets after the title and before the period. Capitalize the first word but do not underline or italicize it.
- You should not describe books, web pages, reports, journal articles, and newspaper articles.
-
Example
- When a source does not have a title, you may describe the work in brackets.
How to write the sources
The source is important in determining where you can retrieve the work. If possible, to identify a source, there are many elements you should add to your citations.
If the work you are citing is a whole work, try to follow this order in your citation:
- Author(s) name(s)
- Publication date
- Title of the source
- Name of the publisher
- Platform, web page, database the source was retrieved
- DOI number or URL
As explained in the above section, your source may be a part of a whole work. If so, try to follow this order in your citation:
- Author(s) name(s)
- Publication date
- Title of the source
- Title of the book/journal/website the source comes from
- Volume and issue number
- Page numbers (if provided)
- Name of the publisher
- DOI number or URL
Abbreviations and example references list
Below is an example of a Reference List. Since each source is from a different category (a journal article, a serial, a document, an image, a book, and a book chapter), you can observe the different ways to cite your sources.
Writing a reference list
A reference list must list every source you used in your academic paper. It must contain the author(s) name(s), date of publication, title, and, if found, more information regarding the source. An APA reference list must follow these rules:
- Write it on a new page at the end of the document
- Write Reference List in the center and at the top of the page. Write it in bold, but do not underline or italicize it!
- Your reference list must be written in double spacing with 1-inch margins
- Your reference list must be alphabetical by the name of first author (In case the author is unknown, the title must be used. However, in this case, “a,” “an,” and “the” of the title should be ignored)
- Your reference list must be centered on the page
In case there are multiple works by the same author:
- The works should be ordered by their dates. If the works are from the same year, they should be ordered alphabetically by their titles and should be assigned a letter (a, b, c, etc.) after their dates.
-
Important
Your reference list must include complete references for all in-text references used. This is particularly important since it counts as plagiarism if you don’t include all the sources when writing an essay or research paper.
Things to avoid
- Do not insert extra line space between citations.
- Do not choose fonts that are difficult to read. 12-Point Times New Roman font is commonly recommended.
