Interlibrary Loan is a free service that allows you to request materials to be delivered to your campus library. There are two options for requesting materials: requesting an item directly from one of the Library Catalogs or using Interlibrary Loan Request form.
Be prepared to wait at least several days for an article and at least a week for a book.
