CLIO is the online catalog for the Columbia and Barnard libraries. It includes over 4 million records for over 92% of the Libraries' collections. Books, serials, journals, newspapers, online resources, government documents, microforms, sound recordings, video recordings, archival collections are listed in CLIO. Catalog records for electronic versions of journals, newspapers, or books may contain links directly to the online full text. Records for items on order or in the process of being cataloged are also included.

Some material is not in CLIO. For example, the collections of the Law, Jewish Theological Seminary, and Teachers College libraries are excluded from CLIO. Other categories of materials are only partially included in CLIO; such as: manuscripts and rare books, South Asian language collections, some periodicals which ceased before 1985, some research collections in microform, maps, data, and collections of pamphlets acquired before 1970.
