The USDA Bureau of Plant Industry Horticultural and Pomological Investigations Records (1892-1960) contain 51 linear feet of black and white photographs, acetate and glass negatives, glass slides, drawings, note cards, project reports, research records, and correspondence related to small fruits and nuts from the U.S. Department of Agriculture Fruit Laboratory.  Examples of topics include experimental fruits, varieties, plant anatomy, breeding, crossing, diseases, insects, irrigation, handling, pruning, harvesting, and marketing.  Many photographs were taken in Beltsville and Glenn Dale, Maryland.

A subset of this collection is a group of 350 images depicting grapevine plants and grounds of the USDA Oakville, California Experiment Vineyard.  This land is now the property of the University of California.
