Keep the following tips in mind in order to avoid plagiarism and use quotes and concepts effectively:

• When directly extracting material use quotation marks and cite the source.
• When re-wording material make sure to cite the source.
• Do not cut and paste directly from the Web.
• Don't resuse term papers or purchase papers on the Web.
• Make sure to write down the complete source information for accurate references.

If you are having difficulty deciding when or how to cite sources, please contact your professor or any reference librarian.  Pius Library keeps copies of all the major style guides at the Reference Desk including MLA, APA Publication Manual and Turabian.  See also Pius' Useful Web Sites links to Style Guides & Manuals.
