Why Do I Need To Cite?

Citing gives credit to the original authors and allows your readers to find and verify your sources. When you use someone else's ideas, data, or words, you must acknowledge them in a reference—otherwise you risk plagiarism. Proper citations also strengthen your work by showing the breadth of your research.
