WorldCat is the catalog for libraries around the world. It can help you discover books and articles beyond what Northwestern has in its collection. You can order books you find on WorldCat through Interlibrary Loan (ILL).
If you are requesting a book via Interlibrary Loan and the item should go directly to the professor when it arrives, write “For Prof. ____” in the Notes field and do not fill in the ISBN field on the ILL form.
You can also request books and articles directly using the Interlibrary Loan form. This is where you can view your outstanding ILL requests and view electronically received articles.
