Citations and Avoiding Plagiarism

Citation Styles

The main citation styles used at Seton Hall are APA, MLA, and Chicago. We encourage the use of the citation tools to the left, or others like Citation Machine. However, you must ALWAYS check your citations when using citation tools, such as citation generators. Understanding the rules of each style will help with this.

The first part of this guide provides online resources for APA, MLA, and Chicago citation styles. The bottom of this guide contains links to the library's APA, MLA, and Chicago manuals, which includes where to find these manuals in the library.
