When do I need to include a DOI in my citation?


When a DOI is assigned to a resource you should include it. 

For more information about DOIs, see the APA Style website.

REMEMBER:  If no DOI is assigned, you must provide the URL of the journal homepage (not the URL within CINAHL or another database)

*See Chapter 7, section 7.01 for formatting examples.
