Books and other items that you have checked out may be renewed online, with some exceptions. Reserve material from any library and items from the Butler Media Collection may not be renewed. Please ask at the circulation desk from which you have checked out books about their specific renewal policies.
To renew online, use the My Library Account link in CLIO. The online service is available to registered borrowers at Columbia University, Barnard College and Teachers College with a currently valid University Network ID ("UNI") and password.
You may not renew books by telephone.
You can renew an item up to 10 times from the original check-out date unless:
- another borrower has requested it
- an instructor needs it for course reserves
- your borrowing privileges are suspended
Please return or renew items promptly to avoid fines and fees.
