Interlibrary Loan (ILL) is a service that allows patrons to obtain research materials not available in our library or through Summit. Current students, faculty, staff, and retired UPS faculty are eligible for this service. To request an item through interlibrary loan, set up an ILLiad account. Most requests are now processed and received electronically so they usually come within 3 to 5 working days. Books are still sent via U.S. mail or courier, so please allow 11-14 days for these materials.
