Plagiarism:  Passing off someone else's work as your own, whether word for word or merely the creative ideas. This can amount to copyright infringement if permission has not been obtained from the copyright owner for use of the expressive elements of the work. Even if permission is granted, putting your name on someone else's work is still plagiarism and is unethical within artistic, scientific, academic and political communities.  NOLO.  Everybody's Legal Glossary.  July 7, 2005  <http://www.nolo.com/glossary.cfm>
