The surviving files of official correspondence, reports, documents, and printed materials of King's College from 1750 to 1784 and Columbia College from 1785 to 1890, as well as Columbia University up to 1964. The King's College era materials include grants, deeds, indentures, lists of governors, leases, accounts, etc. The Columbia College era papers commence with documentation regarding the attempts to revive the college at the end of the American Revolution.

Much material was destroyed and scattered in the late 19th century leaving this collection quite incomplete.

Materials generally consist of newspaper and magazine clippings, press releases, programs, ephemera, printed matter, lists, reports, and pamphlets.
