The Cass Gilbert Papers include photographs of Gilbert’s sketches for a variety of completed and proposed Oberlin College buildings. These depict sketched floor plans, site plans, renderings, elevations for a variety of buildings. Also included are index specifications for construction of the Art Building in 1915 and its mechanical equipment. A pamphlet of sketches for the Theological Quadrangle and a photograph of the plan for the third floor of the Seminary are included. The remainder of the collection includes a photograph of Gilbert himself, a photographic reproduction of a graphic portrait of Gilbert, newspaper articles and clippings about Gilbert’s architecture at Oberlin, and correspondence regarding pending and proposed projects.

The papers have been organized into five series: Correspondence, Drawings and Specifications, Writings by Others, Photographs, and Exhibit Materials.
