San Joaquin County traces its political origins to California's entry into the Union in 1850. By then, the County had already
demonstrated its strategic value as a gateway to California's Central Valley and southern gold fields during the Gold Rush
of 1849. As Gold Fever subsided, settlers also recognized the value of the County's soil and the potential for agricultural
development. The volumes included in this collection reflect intensified farming and increasingly concentrated ownership that
characterized the County during the last part of the nineteenth century and the opening of the twentieth. During that period,
the County's population tripled, from approximately twenty-four thousand to seventy-nine thousand.
Scope and Content
This collection of San Joaquin County Assessors' Plat Books, which is arranged chronologically, spans the years 1876 to 1919.
All volumes are handwritten, and each includes approximately eighty maps that describe property holdings throughout the County.
Among other data included in each book are names of landowners, assessed values of real property, and significant landmarks.
