If the library book you want is checked out, first check CLICsearch for other versions of the book. Sometimes the library has more than one copy or version of an item. If a copy is available at another CLIC library, use the request link in CLICsearch to have the item delivered to Northwestern.
If you still do not find a copy available, you may submit an interlibrary loan request for the item.
To submit an interlibrary loan request for a book, choose "ILLiad book request." You will receive an email when the item is ready for pickup.
