What is plagiarism?
Plagiarism constitutes a major ethical breach, whether committed by a freshman or senior scholar. It is a form of academic dishonesty in which a researcher uses another's words or ideas without giving the originator proper credit. Academic writers generally need not cite well known facts and commonly-held knowledge within their communities (e.g., Art Deco appeared in Europe after World War I).
When in doubt, cite it. Under no circumstances should you lift another writer's words directly from her text and paste it into your own paper without using quotation marks. Many students get into trouble through inadvertent or careless plagiarism. If you have not given proper credit to your source, whether through intentional action or carelessness, it constitutes an act of plagiarism.
