What is Interlibrary Loan?
Interlibrary Loan is a service that allows Ann Arbor District Library cardholders to borrow materials not owned by the Ann Arbor District Library system. Library staff will find another library that has a copy of the item you're looking for, and that library will loan the item to AADL through the mail. AADL then checks the item out to you. After you return the item, AADL mails the item back to the loaning library.

Who can use Interlibrary Loan?
Anyone with a current AADL L-card and less than $10 in fees can place an interlibrary loan request.

What types of materials can I request through Interlibrary Loan?
You can request books (including music scores, pamphlets, dissertations, theses, and government documents), photocopies of articles or book chapters, and microfilm.

How much does Interlibrary Loan cost?

What happens if I lose or damage my interlibrary loan item?
If you lose or damage an interlibrary loan item, you will be responsible for paying any charges determined by the lending library.

What is the check out period for interlibrary loan items?
Due dates for items borrowed through Interlibrary loan will vary as the loan period is set by the lending library.

How long does it take to receive an ILL item?
The length of time for ILLs requested from other libraries varies and can be from 2-4 weeks, or in some cases longer. The time frame for all ILLs depends on availability, shipping, and distance from the lending library.

How will I be contacted when my material arrives?
You will be notified via email or mailed printed notice, depending on the information you supplied when you got your library card.The status of requested ILL items can be viewed on My Account.

Where do I pick up my material and how long will it be held?
ILL books are held behind the Circulation Desk at the AADL location selected when the item was requested. Materials remain on the holdshelf for six days. The last date that the item is available for pick up is included in the notice that it is ready for pick up. The item must be checked out on the account of the person who requested it. Microfilm and Library Use Only materials are held at the Downtown Library’s 2nd Floor desk.

Can I renew my ILL books?

  • For items borrowed through OCLC WorldCat, the window for renewing items is three (3) days prior to due date through the due date. Items may not be renewed once they are overdue. Renewals are one time only and for either two or three weeks (depending on the lending library's preference). To renew, send an email to iloan at or call (734) 327-4219. Indicate you would like to renew an ILL item giving your name, library card number, the title and author. You will be given a tentative three week renewal.
