The Library Information Office (LIO), is located in Room 201 Butler Library, just to the left of the main entrance. LIO staff provide a wide variety of services to faculty, staff, students, and visiting readers, including initial requests for visitor access to the Columbia University Libraries. The office also answers general questions about any of the Libraries’ services and resources, administers user privileges, clears library blocks due to overdue fines/fees, and distributes publications of a general nature about the Libraries.
