Interlibrary Loan

Can't find a book or article at the library, or in the consortium of area libraries? Northbrook Library cardholders may request books, articles, CDs, and DVDs through interlibrary loan.

How do I request an interlibrary loan?
Interlibrary Loan requests can be made at any of the service desks on the second and third floors. Provide as much information about the item as possible such as title, author, publisher and year of publication.

You may also place a request yourself through WorldCat: look for the ILL tab when you find the title you want to request, complete the form, and submit it. You may email ILL at

How long does it take to get an ILL?
The Interlibrary Loan process takes from approximately seven days to eight weeks depending on the location of the book and the lending library's response time. Some materials, like genealogical publications, are difficult to borrow through Interlibrary Loan.

How am I notified when my item comes in?
You will receive an email if you've signed up to receive email notifications for holds, due date reminders, and notices of overdue materials. You can sign up here to receive those notices. If you have not signed up for email notices, you will receive a phone call at the number you've provided.

How long may I keep the book?
The loan period for each item is determined by the lending library.

How can I renew an item?
Contact the Interlibrary Loan office at 847-272-6224, ext. 243. Please note: often Interlibrary Loan materials are not renewable and occasionally are sent for in-library use only. We will make every attempt to renew an item when possible
