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.

Nancy Hopkins Reily (b. 1934) is a writer and photographer. She met O'Keeffe as a child when her family started spending summers in Abiquiu during the 1940s. Her aunt Helen Louise Morten (1900-1984) was a friend of O'Keeffe. Reily has published two books about O'Keeffe. Reily was interviewed by Sarah Burt.
