Why are citations important?

Academic papers are conversations between multiple authors; we agree with, refute, and challenge the ideas of other scholars. Responsible scholarship dictates that we properly credit scholars with their work when it is mentioned - enter citations.

Citations are for transparency and access. In addition to proving that you've done your due diligence as an academic, citations let readers know what you've read and where they can access a source you've used.

How do I cite my sources?

What your citation looks like depends on the style manual that your academic discipline follows. If you don't know where to start (and if your instructor hasn't specified a style guide to follow), the table below gives a basic overview of common citation styles. For more information and specific resources for each style guide, please consult the tabs at the top of this page.

What do I need to cite?

Description of when and when not to cite sources. See below for discussion.

If you are quoting or paraphrasing information, reusing an image, restating information presented in a table, or if you otherwise did not think of the information you are using, a source should be cited. Citations give authors/creators/researchers credit for their work.

I need help formatting my citations!
