The photographs contained in the library make up one of the richest and most comprehensive collections of images which document the history of the great Central Valley of California and the development of agricultural technology. The photograph collections (of over 50,000 images) contain positive prints, stereographs, lantern slides, daguerreotypes, tintypes, ambrotypes, glass plate negatives, film negatives, and 35 mm slides. They cover the period from the Gold Rush to the present, although the bulk of the collection is pre-World War II. Geographically the collections focus on the San Joaquin and Sacramento Valleys, the San Francisco Bay Region, Northern California, and the Mother Lode areas. In addition there are many images of Alaska, Oregon, Nevada and Arizona. Works of over 700 identified photographers are represented.
