APA Citation Style, Seventh Edition: Journal Articles with 21 or More Authors

Section 10.1

In General:

  • When citing a journal article (whether accessed online or in print) that has a Digital Object Identifier (DOI), include the DOI in the reference entry formatted as a hyperlink (i.e., beginning with "https://" or  "http://").
  • If an online work has both a DOI and a URL, only include the DOI in the reference entry. 
  • If an online work does not have a DOI, include the URL according to the rules listed in Section 9.34 of the Manual. For works from most academic research databases, the URL is not required.
  • You can present DOIs and URLs as either standardized hyperlinks (typically blue and underlined) or in plain text.
  • For a work with three or more authors, include only the name of the first author followed by "et al." in every in-text citation, including the first.
  • For a work with 21 or more authors, include the first 19 authors followed by an ellipsis (…) and the last author in the reference entry.
