Borrowing privileges include renewals, item limits, loan periods, renewals, and more, and vary by borrower type. Most items may be returned via library book drops (more about return locations).
In addition to books and media, we also have technology and other items available to borrow.

Log into My Library Account with your Identikey to view items checked out to you, renew items, or see if you have any holds or fines. Request items online through the library catalog for hold pickup. CU staff, faculty and graduate students with campus mailboxes may request items for delivery there (more information about campus mail delivery).
