NOTE: Pages for individual citation styles have been merged into this single Style Guides page. Please update any links; individual style guide pages will be deleted at the end of the Spring semester.
Overview
The way that citations appear depends on the citation style, which is a set of established conventions for documenting sources. There are different sets of conventions for different fields of study and scholarship.
On this page are links to guidance for many of the most common styles. For assignments, when in doubt, consult with your instructor.
On the guide's navigation menu, you will find links to other valuable information about citation:
- Confused about why we cite and why there are different styles?
- Looking for information about which online citation generators to use and how to use them effectively?
- What should I do when using generative AI tools?
- How do I use software to help organize my sources and cite them correctly?
