Once you have verified that the book you are looking for is either not located in the catalog or all copies are checked out, you may search the I-Share catalog to see if one of the participating institutions has a copy for you to borrow. The process is the same for requesting a book in the I-Share catalog as it is for the Illinois catalog. Items typically arrive within 5-10 days and you will receive an email when the item is available for pick up.
If the item is not available in the Illinois catalog and it is not available through I-Share, then your next stop will be Interlibrary Loan and Document Delivery. What is Interlibrary Loan? First, keep your full citation handy -- you'll need it. Second, login to the ILLiad server using your NetID and password. From the ILLiad main menu, select "Request a Book." Be sure to fill out as much of the form as possible, including the source of your citation. This will ensure that ILL can place your request in a timely manner. You'll be notifed by email when your item is ready to be picked up.
