In 1921, one Jervie Henry Eastman set up a photographic studio with the intent of providing commercial photography services to residents of Northern California. Over Eastman's long career he took photographs of logging camps, dam construction, the construction of the University of California-Davis campus, and numerous other subjects. While the online collection does not have a detailed finding aid, visitors can search the contents with a search engine offered here. Each photograph is accompanied by detailed information on its provenance, along with an image description, and subject headings. The collection is quite extensive, as it features over 13,000 images that may be of great interest to those in the fields of urban history, historical geography, and the Golden State in general.
