Thank you to the many people who worked on making these maps accessible. The maps have been part of the Branner Earth Sciences Library and Map Collections since 1989 when they were transferred to that library after the Loma Prieta earthquake. Prior to that they were part of Stanford's Central Map Collection in Green Library. Tamar Ravid and Andria Olson were responsible for finding and pulling the maps for digitization. The maps were scanned by the Digital Library Systems and Services team. Preparation of the materials was handled by Peter Crandall. Meagan Trott managed the digital release of the materials into Searchworks. The digitization workflow was overseen by Andria Olson.
