- Please check University Libraries Catalog or ask a Reference Librarian to be sure we do not have the item(s) you need.
- Then, try Prospector for faster delivery of books. Prospector is a self-service, rapid delivery borrowing service.
- Complete an Interlibrary Loan Request if needed. Request material through Interlibrary Loan if it is unavailable from University Libraries or Prospector.
- Interlibrary Loan requests can be made directly from library databases using ArticleLinker. See the library guide to ArticleLinker.

Articles will be delivered to your ILL account as PDF’s that you can download, typically within 5-7 working days. Hardbound material arrives within 7-10 working days. Occasionally items may not be obtainable due to scarcity, lending policies of owning institutions, etc. Please note: the status or listing of your ILL materials will not be reflected on your main Library account.

It is important to maintain good working relationships with libraries that loan to us. Our borrowing privileges can be revoked by lending libraries if patrons do not return materials on time. Overdue materials may result in a loss of an individual’s Interlibrary Loan privileges. Charges for book replacements are determined by the lending institution and can exceed $100.00.
