Citing Sources

Information about academic integrity, avoiding plagiarism, and guides to creating citations in a variety of styles, such as APA, MLA, AMA, Chicago and more.

Interpreting Citations

Not only is it important to be able to create citations in your own work, it can also help you to be able to understand what a citation is referring to when you come across one. 

For example, say your professor says you need this item: 

Grendler, Paul F. The Universities of the Italian Renaissance. Johns Hopkins University Press, 2002

Would you look for it in the catalog, with books? Or in the databases with journal articles? In this case, based on the information that is included, this citation has told us that this is a book: Journal articles don't have a publisher (in this case, the publisher is John Hopkins University Press)

Maybe, while doing research, you come across this citation in another article's Works Cited list:

Davies, Jonathan. “Violence and Italian Universities during the Renaissance.” Renaissance Studies, vol. 27, no. 4, Sept. 2013, pp. 504–516. EBSCOhost, doi:10.1111/rest.12027

If you are familiar with citations, this you can recognize as journal article: Books usually don't have volume and issue numbers (vol 27, no 4). The "Article," in quotes, is published in the Journal, which will always have its title italicized

If this sounds confusing at first, that's ok--the more you cite, the easier it becomes.

Style Differences

Used to using MLA, but now you need to use APA? Taking a history class for the first time, and now your professor is using Chicago? This page has side by side comparisons of how to cite different resources in each style
