Our APA citation guide was compiled with the help of useful information from Purdue University's Online Writing Lab. The Proctor Library's reference sheet for APA citations can come in handy as well.
Note: The Publication Manual of the American Psychological Association states (p.192) that including database information in citations is not necessary because databases change over time. When referencing a print article obtained from an online database (such as a database in the library), provide appropriate print citation information. By providing this information, you allow people to retrieve the print version if they do not have access to the database from which you retrieved the article.
