APA Style

APA Manual

APA (American Psychological Association) citation style is a set of guidelines that explain how to properly give credit to the books, articles and other resources you used in a paper or assignment. This guide is based on the Seventh Edition of the Publication Manual of the American Psychological Association (sometimes just called the "APA Manual").

This guide covers the most common types of citations that college students use but for more examples and explanations you might want to check out the original book.

You should follow your instructor's guidelines regarding what is an allowable source (eg. peer reviewed academic journals v. websites).

A copy of the handbook is kept at the Reference Desk on the second floor of the library.  Please ask the librarian if it's available.
