Why Cite Your Sources?
Citing your sources thoroughly and accurately isn't just a good idea—it's the law.
What is Plagiarism? 

Plagiarism is a difficult concept to define. It includes a range of actions from failure to use proper citation to wholesale cheating. A student who plagiarizes may do so unintentionally or it could be a deliberate adoption or reproduction of ideas or words or statements of another person as one’s own without acknowledgement.
