I need help with citations.

Your COS Librarians have created library guides that can help you cite your sources. See the online guides for three of the most commonly used citation styles at COS:

• Modern Language Association (MLA)
• American Psychological Association (APA)
• Chicago​ Style

Learn how to access these citation guides from the COS homepage by watching the video below.
