If you need anything Bell Library doesn't own, Interlibrary Loan is the service that can find those materials to you!
Usually, we'll be able to get the material in a few days, but a hard copy (like a full book or journal issue) will take us a little longer.
Don't forget: If you are currently a registered Distance Learner with the Registrar's Office or designated as a Remote Researcher; you can have books from Bell Library’s Main Collection, and borrowed interlibrary loan materials, shipped directly to your home for free. We also supply a prepaid return label for your convenience.
