This collection included primarily original and reprographic architectural drawings by Roth, circa 1907-circa 1949, largely of apartment buildings located in Manhattan and designed during the 1920s and 1930s. Represented are the San Remo Towers, The Beresford, The Oliver Cromwell, the Normandy, and numerous other apartment buildings. There are also drawings for several hotel and private residences. A two-volume typescript autobiography is also included.

This collection contains architectural photographs, drawings and records related to the architectural projects and designs of Warren and Wetmore, principally in the United States, but also representing commissions in Canada, Cuba, and Puerto Rico. Unfortunately, the bulk of architectural drawings produced by the firm are no longer extant. Additionally, it holds a variety of photographs and other records used as reference materials in the course of Warren and Wetmore's professional work. Lastly, a small group of student and personal papers and photographs from Whitney Warren completes the collection.
