Purdue University's OWL (Online Writing Lab) has easy-to-use online style guides for MLA, APA, and Chicago Style. These are a great place to start if you are looking for help with a particular citation style.
Each guide outlines basic rules for in-text citations, works cited lists, and bibliographies. This includes how to cite different kinds of books, journal articles, websites, videos, images, and much more.
Citing images correctly is just as important as citing written sources in your work. The following guides provide specific guidelines for citing images from some of the most common sources.
The library also holds print copies of the main style guides, which cover every aspect of each citation style. You may need these for information on how to cite sources not covered in the online guides, such as performances, or didactic panels in a museum exhibition.
