Lorie Kloda & Karen Nicholson (both of McGill University Libraries) have posted Plagiarism Detection Software and Academic Integrity: The Canadian Perspective on Resource Shelf.  Here is the abstract:

In this study, we seek to determine how leading Canadian universities using text-matching software address issues of academic integrity. Particular attention will paid to the role of librarians in promoting academic integrity and in educating students and faculty about information literacy. Having identified seven of the G10 currently using Turnitin, we intend to survey key stakeholders from each institution via electronic questionnaire for information on four areas relating to academic integrity: promotion, policy, education, and library involvement. We expect to report a summary of our findings, paying special attention to the current situation at McGill.
