What does stored mean?
Stored books and periodicals are in compact shelving in the East Wing of the Oviatt Library. (See http://library.csun.edu/About/ASRS )
When you find a OneSearch record for an item you'd like with Location: Stored, just click the link to Request the item. Log in with your portal ID and password. The item will be available for you to pick up at Guest Services in the main lobby in approximately 10 minutes.
Most items in storage can be checked out and taken home.
