APA 6th Edition: Basics: Journal Articles

Basic examples for citing sources in APA style for undergraduates or those with little experience using APA.

What is a DOI?

The DOI System provides a means of persistent indentification for managing information on digital networks.

So, what does that mean excatly? SOME articles are now assigned a unique identifier that is a direct link to the information, regardless of where it resides.  These Digitial Object Identifier numbers are unique alphanumeric strings that provide a persistent link to the location of the information on the Internet.

Why is this important? Have you ever clicked on a link and found that it is broken or no longer working? This DOI system replaces the use of URL addresses in citations. When a DOI is used, the location and publisher of the work is NOT included.

ALL DOI numbers begin with a 10 and contain a prefix and a suffix separated by a slash.

*DOI: 10.1037/0278-7393.34.3.439

*When the DOI is used in the citation, the letters are not capitalized.

The DOI is typically found on the first page of the electonic journal article, near the copyright notice. It can also be found on the database landing page for the article.

Use the DOI when it is available, instead of the URL for an electronic journal article. If you can't find one, use the HOMEPAGE OF THE JOURNAL and not the database name (this usually can be found from a simple Google search).  See the examples below. Need more help?
