Plagiarism: A Definition

Plagiarism is the use of another's words and ideas without giving credit and claiming them as your own.

Most cases of plagiarism by college students are unintentional and due to mistakes or misunderstandings about how to cite properly.

This guide will help with citing a variety of sources and using in-text citations.

If you didn't write it, you have to cite it.
