The Georgetown University Honor Code—which includes a detailed definition of plagiarism—can be found on the GU website at http://gervaseprograms.georgetown.edu/honor/
system/53377.html. In short:
Plagiarism is the act of passing off as one’s own the ideas or writings of another. While different academic disciplines have different modes for attributing credit, all recognize and value the contributions of individuals to the general corpus of knowledge and expertise. Students are responsible for educating themselves as to the proper mode of attributing credit in any course or field….[T]hree simple conventions are presented for when you must provide a reference: 1) If you use someone else's ideas, you should cite the source; 2) If the way in which you are using the source is unclear, make it clear; 3) If you received specific help from someone in writing the paper, acknowledge it….Faculty may use various methods to assess the originality of students' work. For example, faculty may submit a student's work to electronic search engines, including turnitin.com, a service to which the Honor Council and the Provost subscribe. Note that plagiarism can be said to have occurred without any affirmative showing that a student’s use of another’s work was intentional.
I follow Georgetown’s guidelines for plagiarism. I also submit all student work to turnitin.com, an electronic search engine that detects instances of plagiarized writing. If you have any uncertainty about the meaning of plagiarism, please be sure to discuss it with me.
