The Mary Rutherfurd Jay collection documents Jay's career as a landscape architect, her lectures on gardens, and her involvement in the profession. Research notes and images on gardens around the world and architectural drawings form the bulk of the collection. There are also photographs of her commissions but no textual project files. The collection is arranged into four series: Personal Papers, Professional Papers, Project Records, and Art and Artifacts. Jay's personal papers relate to her education at Harvard's Bussey Institute and include a photograph album of a vacation to Quebec, Canada with family and friends. Her professional papers include notes, research materials, and photographs related to her travel to gardens worldwide and her illustrated lectures about these gardens. Her most common specialty appears to have been Japanese gardens. This series also includes scrapbooks of clippings about her lectures, and copies of her published articles. Jay's project records consist primarily of architectural drawings and photographs. The collection also contains horticultural plant cards and a plaque about her collection from the Reef Point Library. This collection was given to the University of California, Berkeley as part of the Reef Point Gift of Beatrix Farrand. Originally included in the Jay Collection was a collection of @ 2800 lantern slides which were transferred to the CED Slide Library and converted to 35mm. A list of these images is available upon request.
