This study presents data and commentary from 50 academic library directors or other high level executives about their library role in addressing plagiarism.  The advent of generative artificial intelligence and its broad use in academia has created a plethora of new questions about exactly what plagiarism is, how it should be identified and policed, and how academic libraries should respond.  Traditionally, academic libraries have played a major role in defining and explaining plagiarism to students and developing strategies to eliminate it.  This role has assumed greater importance.The report gives detailed data on the rate of increase in instances of plagiarism, and on how librarians evaluate the seriousness of the problem at their institution.  It also presents data on the percentage of libraries that offer access to Turnitin and similar applications, and measures librarian confidence in automated efforts to detect plagiarism, especially AI-assisted plagiarism.  Librarians also offer insights on how clear that they feel are their institution's definitions of and policies on plagiarism, and what are some of the best methods for combatting plagiarism on campus.
