Western takes academic integrity very seriously and sanctions students for even accidental plagiarism. A number of tools exist to help students learn proper citation and paraphrasing, as well as what is considered a scholastic offense.
Western Libraries are a wonderful resource for both research and academic advice. They have a plagiarism guide available to help you determine if you've cited a passage properly. The Office of the Ombudsperson also produces an online brochure covering what you need to know about Cheating, Plagiarism and Unauthorized Collaboration.
