Library Information Office
(Redirected from LIO)
The Library Information Office (LIO) is located in Room 201 of Butler Library, just to the left of the front door.
Besides answering general questions about the Columbia University library system, it offers a variety of services, including assistance with visitor access, management of the library's lockers and processing of fine payments for overdue/lost library materials. The last service is especially important, considering one needs to have all library fines cleared in order to receive a diploma.
Fine Payments
The LIO accepts the following payment options for fines:
- Credit card (Mastercard or Visa) - including payment by phone (tel: 212-854-7309)
- Check (made payable to "Columbia University Libraries")
- Money order
Opening hours
- Monday through Wednesday: 9am–6pm
- Thursday: 9am–8pm
- Friday: 9am–6pm
- Saturday: 11am–6pm
