The Willa Cloys Carmack Collection spans the years 1916-1962 and includes personal, professional, and project records. This collection is organized into two series: Personal Papers, Professional Papers.

Series I: Personal Papers contain correspondence, photographs, travel diaries, and handwritten notes about plant types. Much of the correspondence are postcards to Willa’s children during her travels and a few to friends. Photographs include a headshot from the 1916 Blue and Gold yearbook noting her graduation from UC Berkeley. The bulk of material in this series is travel paraphernalia from her trips to Italy (1926), Mexico (1955), across the Midwest (XX), and Japan (1956).

Series II: The Professional Papers include correspondence relating to professional topics, writings, presentations, professional organizations and committees, reference material collected, and project records. Reference Files are the largest sub-series containing nursery lists with handwritten notations, brochures by plant type, and reference materials such as magazines and newspaper clippings related to the profession in general and not to specific projects.
