Interlibrary Loan is an incredible service that the library provides free of charge to students, faulty, and staff. This service can get you a book we don't own a copy of, a pdf of an article we don't have access to, and even a DVD of a movie we don't own. The three videos below will introduce you to the service and tell you how to request a pdf of an article and also physical materials.
