Interlibrary Loan FAQ

Find out who is eligible, what you can get, loan times, fines etc.


SDSU's Imperial Valley Campus Materials (IVC)

Materials held at the SDSU Imperial Valley Campus (IVC) in Calexico, CA are included in our online catalog, the PAC, and are available for immediate ordering directly from the PAC. When you find a record for an IVC book you need in the Library Catalog (the PAC), click on the REQUEST button and follow the prompts to place your order.   Books from the Imperial Valley Campus are delivered here and available for pickup at the main Circulation Desk within 3-5 days.  Loan policies and fines are the same as those for books checked out from the main SDSU collection (see the Borrowing (SDSU) page for current policies).


Circuit is the fastest way to get a book that's not held in the SDSU Library collection.  But only books are available for loan through Circuit (no journal articles).  This union catalog contains the collections of the libraries of UCSD, USD, CSU San Marcos, San Diego County Libraries, and San Diego Public Libraries.  Books are generally available for pickup at the Circulation Desk within 1-2 days.  If you are searching for a book in the Catalog, but cannot find it, click on the REPEAT SEARCH IN CIRCUIT.  You will then be directed to the Circuit website.   Once you find the item in Circuit, click on REQUEST THIS ITEM and follow the prompts.  More details can be found on the Circuit Help Page.


If you are looking for a book and can't find that book through SDSU or Circuit, either because we don't own it or it's checked out, you can use WorldCat to locate your book and request it using Interlibrary Loan. WorldCat is a catalog that indexes thousands of libraries materials worldwide. This video will take you through the steps to check for your book in the catalog, and then search in Circuit and finally search in WorldCat and request the book from WorldCat using Interlibrary Loan.

A tutorial for WorldCat can be found here: How to Find Books in WorldCat

Interlibrary Loan (ILL)

Interlibrary Loan (ILL) is able to acquire a much broader range of materials.  When you submit an Interlibrary Loan request the system and staff will search other library catalogs worldwide to find the item you need. Once the item is located in another library's collection, your request will be placed.  We are able to obtain around 90% of all materials requested.  For more details, please see our frequently asked questions page.  For questions or concerns, please email ILL at
