A DOI is a unique identifier that provides a persistent link to an article online. APA style now requires a DOI when citing scholarly research articles that are found online (including Oregon Tech library’s databases).
Example: Brinkmann, S. (2009). Facts, values, and the naturalistic fallacy in psychology. New Ideas In Psychology, 27(1), 1-17. doi: 10.1016/j.newideapsych.2007.10.001
What if the article I am citing does not have a DOI?
Some research databases, such as Academic Search Premier, PsycINFO, and PsycARTICLES, include DOIs in their article records (if one is available). If a database does not include a DOI in its article records, use CrossRef.org website’s “free DOI lookup” to see if a DOI exists for that article.
What if CrossRef cannot find a DOI?
If the DOI of the desired article is still unavailable, two alternatives are acceptable:
- Give the exact URL of the article (if it is in open access and no sign-in is required)
- Give the URL of the journal publisher’s home page (if it is from a licensed database)
