The Harold A. Stump collection consists of correspondence, photographs, research files, and lecture notes that document his travels and teaching career. Personal papers include a large collection of letters to his siblings, family photographs, and student work. Research files document his interests in aesthetics and architecture and include research for lectures and classes he taught. Stump's collection of slides was donated separately to the Architecture Visual Resources Library to form the Harold Stump World Architecture Slide Collection.

The Harold Stump collection is organized into three series: Personal Papers, Faculty Papers, and Additional Donations. The collection consists of correspondence, research files, writings, faculty administrative documents, and photographs relating primarily to Stump’s teaching career at UC Berkeley’s Department of Architecture and College of Environmental Design from 1939 to his retirement in 1972. Also included are a large number of personal and professional letters concerning research, travels, and UC Berkeley departmental policies and activities.

The bulk of the Personal Papers consists of correspondence to Stump and includes letters from Stump to his siblings during travels abroad. Student work includes writings, drawings, and academic records. Also included are travel records, personal and family photographs, datebooks from 1969-1992, and information relating to the Stump Foundation’s proposed publication of writings by and about Stump.

Faculty Papers consist of administrative materials from UC Berkeley including correspondence, policy development, reports, course development, scholarships, and salary information. Course materials document Stump’s teaching career at Fremont High School and his architecture classes at UC Berkeley including lecture notes from several presentations. Research and reference files relate to Stump’s extensive research on Ethiopia, various writings on artists and architects, and his research during the 1940s on the relationship between architecture and aesthetics. Of interest is his correspondence with prominent architects and theorists pertaining to architecture and aesthetics in English and French. Correspondents include Hans Albers, Marie-Anne Febvre (working for Le Courbusier), Walter Gropius, Fernand Leger, Eric Mendelsohn, Lazlo Moholy-Nagy (of the Chicago School of Design), Amedee Ozenfant, Theophile Robert, Ludwig Mies van der Rohe, and Frank Lloyd Wright. Also included in Faculty Papers are some students’ written work, documents relating to Stump’s promotion to full professor, records and reports of sabbatical travel and research from 1952-1953, 1960-1961, and 1969-1970; and documentation of a Fulbright scholarship sponsored teaching assignment in Turkey in 1967. A number of photographs, negatives, and slides documenting architecture worldwide are also in the collection, supplementing the donation of more than 30,000 of Stump’s slides to UC Berkeley’s College of Environmental Design Visual Resources Center .

The Additional Donations series contains a group of letters from Stump to Labelle Prussin. The first letters were written in 1970 while on a tour of the middle east. The second letters were sent from the American University of Beirut in 1972.
