Maps and Documents
We have maps dating from the late 19th century to well into the 20th century, providing valuable information about land ownership, boundaries, and the general trajectory of growth in our community. Our document collection includes newspapers, yearbooks, studies, meeting minutes and notes, and ephemera such as letters, brochures, and even menus. As with our other collections, it is our intention to provide access to all of our collections on-line, as time and resources permit.
This map, dated 1909, is the "Final Report" on the status of the El Sobrante land grant. The original copy is in the hands of local businessman, Richard Oliver, who generously allowed us to take detailed photos of this rare and fragile artifact.
