Citation Elements

In APA citation style, print and electronic sources are treated the same. 

Articles from a periodical are often the most common source to be cited in an APA paper. If a DOI has been assigned to the article that you are using, you should include this after the page numbers for the article. If no DOI has been assigned and you are accessing the periodical online, use the URL of the website from which you are retrieving the periodical. 

Formatting for an article (spacing has not yet been formatted):

Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Periodical, volume number(issue number), pages.

DOIs and URLs

What do I add to the end of my citation? 

  • If there is a DOI number (check the article or database record for the DOI), add it to the end of the citation as a hyperlink (this is new to the 7th Edition of APA). Do not put a period after the URL.
  • If there is no DOI, add the homepage URL instead.
