What is plagiarism?
According to the Temple Student Conduct Code (page 4), "The term "plagiarism" includes, but is not limited to, the use, by paraphrase or direct quotation, of the published or unpublished work of another person without full and clear acknowledgment. It also includes the unacknowledged use of materials prepared by another person or agency engaged in the selling or distribution of term papers or other academic materials."
Plagiarism can also be inadvertent. If you are careless, you may be unaware that you've used someone else's words or ideas. If you haven't given credit to your source, whether you are aware of it or not, it is still plagiarism.
