Citing Sources

College-level writing involves bringing together the ideas of others alongside your own.  To do so, you must properly give credit where credit is due. This means always including proper citations, which also helps you to avoid plagiarism. Plagiarism happens when you try to pass off someone else's ideas as your own or turn in others' work as your own. Students sometimes plagiarize unintentionally by not correctly citing their work.

Fortunately, there is help! A great place to start is the Writing Center. Below are some other helpful links organized by style to help you cite like a pro.
