Series 4: Faculty and Staff includes faculty meeting minutes; basic files the department maintained on faculty members (which may include clippings, correspondence, curriculum vitae, and photographs); as well as the more extensive files of longtime faculty members such as A.F. Buddington, B.F. Howell and William Taylor Thom. Files on Arnold Guyot primarily contain research about Guyot; other faculty files may have been maintained by the faculty themselves and include material such as correspondence (some personal); publications; course and lecture materials including examinations; diaries and field notes; biographies and bibliographies; faculty contracts and recommendations; photographs; and an autograph book as well as letters kept primarily for autographs. William Bonini's files include a box of his gravity journals, notebooks of field observations.
