For materials that are not available via Northwestern, or books that are checked out by someone else, you can submit an interlibrary loan request to have a copy of the item sent here.

If time is tight and you are willing to travel to another library in the Chicagoland area, take advantage of our Reciprocal Borrowing agreements with the University of Chicago, Loyola University of Chicago, and University of Illinois Chicago.
