Proper citation of the sources you use to support your research papers, presentations, and experiments is an essential element of being a student and a scholar. Not only does careful and correct citation allow others to understand your argument, identify the information that supports it, and locate that information, but it also ensures that you will avoid plagiarism and give proper credit to the scholars that came before you.

In addition to the format and methods for citing references, each different style has specific rules about formatting your paper (including things like page numbering, title page layout, proper abbreviation, and more).

The resources on this page provide examples, tips, and useful information about various citation formats and styles, so you can properly cite the resources you use in your academic work.
