The Barney Ebsworth papers date from 1973 to 1982 and include correspondence, notes and writings, printed materials, and photographs and film of works of art by Georgia O'Keeffe. The papers are comprised primarily of correspondence between Ebsworth and Doris Bry, Georgia O'Keeffe's commissioned sales agent, and notes on the legal proceedings between O'Keeffe and Bry (O'Keeffe v. Bry, 456 F. Supp. 822, S.D.N.Y. 1978).

The collection consists of interviews with Georgia O'Keeffe's surviving relatives, colleagues, friends, and employees as well as supporting project documentation. The bulk of the materials date from 2000 to 2003 and include audiocassette recordings, typed transcripts, photographs, and research and project records.
