How do I Cite My Sources?: Citation Styles

Where to find information on citing sources in styles including APA, MLA, AMA, and Chicago.

What Citation Style Should I Use?

Always use the citation style that your professor requires.  

If you are free to choose a citation style, use one you feel comfortable with, and use it consistently and correctly for the entire assignment.

Many of the resources on this page are style manuals - they provide information on all aspects of formatting papers in a particular style. These manuals usually have 1 or 2 chapters on how to cite sources.

APA Style

APA is used in the social sciences. It is also commonly used in business and education.

AMA Style

AMA is used in medical and health fields (with the exception of pyschology).

MLA Style

MLA is used in the humanities.

ACS Style

ACS Style is used in Chemistry. This guide is only available as an online resource (linked below).

Chicago Style

Chicago is used in the humanities, especially History. (If you have been told to use Turabian style for citations, it is almost identical to Chicago.) 

IEEE Style

IEEE is used in Engineering.
