The Osborn Manuscript Files contain single, unbound manuscripts and small groups of manuscripts acquired for the Osborn Collection which the Library has chosen to describe in finding-aid style lists rather than as discrete entries in Yale University Library's on-line public access catalog (ORBIS). The materials in the Osborn Manuscript Files include literary and historical manuscripts, individual and small groups of letters, and single documents, as well as some "Unprocessed" material such as engraved portraits and bibliographic information.
