This guide includes information about citing your sources, including MLA, APA and Chicago / Turabian citation styles.

APA Manual

Publication manual of the American Psychological Association: The official guide to APA style (7th ed.). (2020). Washington: American Psychological Association.

In this seventh edition, the editors finally conceded to good sense to recommend only one space after punctuation at the end of a sentence, a stance that took academic Twitter by storm. But there are more significant updates to the previous edition (2010) that make scholarly communication clearer and more effective. (from Booklist, February 1, 2020)

This handbook is currently on order. This status will change when it arrives. 

Publication manual of the American Psychological Association (6th ed.). (2010). Washington, DC: American Psychological Association. 

This book is the foundation for APA Style. If you have a question that isn't answered by this guide, check in the Handbook. Ask for it at the Help Desk - 808 PUB.

Citation Resources in Databases

Many of our article databases will help you format your citations by giving you a citation that you can copy and paste to your References page or into NoodleTools using the quick cite "Copy & Paste" feature within a citation template.

Gale databases (e.g.,Gale eBooks, Students in Context, U.S. History in Context, Literature Resource Center) - When you click the title of an article, look for the "Tools" on the top of the page and select "Cite."

ProQuest databases (e.g., SIRS Issues Researcher or SIRS Discoverer) - After you have selected an article, click the "Cite" link in the green box to the article title.

You should always double-check the results you get, since sometimes the citations need some clean-up.

What does DOI mean?

Some database articles may include a DOI, a Digital Object Identifier, a unique number that is assigned to an entity that is available on a digital network. The DOI allows networks to keep track of objects such as electronic journal articles, even when the objects are moved from one Internet location to another.  
When an article contains a DOI, APA style allows for the inclusion of the DOI at the end of your citation. Here's an example of an APA citation that uses a DOI:

Wainberg, M. (2009, March 17). Criminalizing HIV transmission may be a mistake. CMAJ: Canadian Medical Association Journal, 180(6), 688-688. doi:10.1503/cmaj.090249
