How do I request items from another CSU?

To request an item through CSU+ you will need to type the title in OneSearch and choose the “All CSU Libraries” option to search for the item at other CSU libraries. If the title is available at another CSU, “Check availability from other CSU libraries” will appear. Click the link to request. Be sure to log in using your CSUN username and password in order to see the “Request from other CSU libraries: CSU+” option to submit a CSU+ request.

How will I know when my CSU+ item is available and where do I pick up my requested item?

Interlibrary Loan will notify you via email when your CSU+ loan has arrived. Interlibrary Loan materials may be picked up on campus using the Library’s Locker Pickup Service which is available 6:00am – 10:00pm, seven days a week. Your Interlibrary Loan item(s) will be held in the locker for 6 days. You may request more time to pick up your Interlibrary Loan item(s) from the Library lockers before the 6 days are up by contacting the department at or (818) 677-2294. If your loan is not picked up in 6 days Interlibrary Loan will return the item(s) back to the lending institution and you will need to submit a new request.

Where do I return my CSU+ Loan?

Starting August 30, 2021, you may return items inside the Library during Library open hours or you may return the loans to one of the Library book drop bins* at any time. More information, including what types of items should not be returned to the book drops can be found in our Returning Library Materials/Book Drops page.

*Please note that items returned to bookdrops are not cleared from your account until the items are inspected by the University Library staff which can take up to a week to process. Your Library account will be updated once the items have been officially checked-in.

Library returns may also be mailed back to the Interlibrary Loan department at the user’s expense to this address:

University Library
Attn: Interlibrary Loan, Room 109
California State University, Northridge
18111 Nordhoff Street
Northridge, CA 91330-8327

How long is the loan period & are CSU+ items renewable?

The CSU+ loan period is 16 weeks from the time of check out. These materials are NOT renewable. If a CSU+ item is still needed after the 16-week loan period, the loan must be returned and you may submit a new request for that same title again.

What if my CSU+ request gets cancelled?

If your CSU+ request is cancelled, your request probably could not be filled by another CSU. If you receive a cancellation notice for your CSU+ request you may submit an Interlibrary Loan request through ILLiad and Interlibrary Loan will attempt to get the item from another institution most likely not from another CSU.
