APA citation guidelines (6th edition)

APA citation

APA style is one of the most common formats for citing sources Other well known citation styles include MLA and Chicago.

APA Style citations consist of two parts:

  1. In-text citation: A brief citation in parentheses when you mention a source, citing the author’s last name and the year of publication, e.g. (Smith, 2019). It identifies the full source in the reference list.
  2. Reference list entry: Full publication details listed on the reference page, which appears at the end of your paper. The reference provides all the information needed to find the source, e.g. Smith, P. (2019, April 18). Citing Sources in APA Format. Retrieved April 21, 2019, from https://www.scribbr.com/apa-style/

This citation guide is based on the 6th edition of the APA Manual. The latest edition, published in October 2019, is not yet supported, but we have compiled a quick guide to the most important 7th edition changes.

In-text citations

An in-text citation is a concise way to show the reader where the original idea came from and to give credit to the original author. Use one every time you quote or paraphrase a source.

Include the author’s last name and the year of publication. When quoting a source, it’s also necessary to include the page number(s) of the quote.

  • An earlier study in which X and Y were compared revealed that … (Smith, 2017).
  • Smith (2017) shows how, in the past, research into X was mainly concerned with …

2 authors

When there are two authors, separate their last names with an ampersand (&), or with the word ‘and’ when they appear in the running text.

  • Research shows that there is a great need for … (Reynolds & Thomas, 2014).
  • Reynolds and Thomas (2014) write that there is a great need for …

3-5 authors

When there are three or more authors, separate their last names using commas. The last two authors’ last names should be separated by both a comma and an ampersand.

  • Recent research suggests that there is … (McGuire, Morrison, Reynolds, & Thomas, 2014).
  • McGuire, Morrison, Reynolds, and Thomas (2014) argue that …

If you cite the same source again, to save space, you shorten the citation. Instead of including all the authors’ names, include only the first author, followed by “et al.” (meaning “and others”).

  • In this research, many participants made use of … (McGuire et al., 2014).
  • McGuire et al. (2014) noticed that …

6 or more authors

If a source has six or more authors, use the shortened version from the first citation.

How do I cite a source with no author in APA?

When no individual author name is listed, but the source can clearly be attributed to a specific organization – for example, 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 your reference list and in-text citations.

When no author at all can be determined – for example, 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 and shorten it if necessary.

How do I cite a source with no page numbers in APA?

When you quote or paraphrase a specific passage from a source, you need to indicate the location of the passage in your in-text citation. If there are no page numbers (e.g. when citing a website), 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.

When should I include an access date in an APA citation?

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 likely to change over time, it’s a good idea to include an access date. In this case, place the month, day, and year directly after the word “Retrieved”, and before the URL.

When should I use “et al.” in APA in-text citations?

Depending on the number of authors a source has, an APA in-text citation is shortened by using “et al.” (meaning “and others”) after the first author’s name.

Sources with 3–5 authors are written in full the first time and shortened from the second citation onwards. Sources with 6+ authors are always shortened, even the first time.

  • First in-text citation: (Taylor, Kotler, Johnson, & Parker, 2018)
  • Subsequent in-text citation: (Taylor et al., 2018)
