APA 7th Edition

You have been asked to use the Publication Manual American Psychological Association: 7th edition, more commonly called "APA style" or "APA 7." This citation style is most commonly used in the social sciences of psychology, sociology, healthcare, and other related fields. Some people find it helpful to purchase a copy of the manual if they are going to be working extensively in a field that requires APA. For most people, they can get by using the various free online resources. It is not necessary to purchase a copy of the manual to be successful in this course. Most questions can be answered by using the APA Style Blog or the Purdue Online Writing Lab (OWL) APA Style (7th edition) guide.

Basic Example


Journal Articles

Do I need a URL?

If the journal article has a DOI, give the DOI as a link. If there is no DOI, do not include the URL.

If you are citing a newspaper or magazine article, give the permanent URL to the article you are citing. 

If you are citing a web page or other piece of online content, give the permanent URL to the page.

If you are citing an e-book that has a physical counterpart, treat it the same as the print edition and do not include a URL.

What about works with multiple authors?

APA 7 lists up to 20 author names in a reference list citation.
