Targeted instruction that teaches international students about plagiarism is an important service that academic libraries can offer. Offering such instruction as an asynchronous, online workshop has distinct benefits in terms of flexibility and ease of learning, but it must be designed with the needs of international students in mind. This study describes one library's online anti-plagiarism workshop, as well as the results of a qualitative study to determine how such a workshop can best be designed to meet the needs of international students.
