Columbia Libraries' main card catalog, located in 310 Butler, provides an historic record of materials in the Libraries' collections up to the mid-1980s. It is divided into three sections:

• Names/Titles
• Topical Subject
• Serials

If you do not find what you are looking for in CLIO, especially when searching for older books and journals, use the main card catalog.

Other Columbia libraries, such as the Rare Book & Manuscript Library and Starr East Asian Library, also have card catalogs. Please feel free to ask a librarian to assist you in using the card catalogs.
