The following mission statement was adopted by the Historical Society’s Board of Trustees in December 2008:
The San Joaquin County Historical Society preserves and interprets the history of our county.
The Historical Society provides educational experiences that showcase the county's traditions of ingenuity, innovation, and invention -- with emphasis on San Joaquin county's singular contributions in agriculture -- to promote community pride, continued learning, and an appreciation of regional history among county residents and visitors.
The San Joaquin County Historical Society accomplishes its mission on behalf of the County of San Joaquin by:
The San Joaquin County Historical Society is a California nonprofit corporation, tax exempt under section 501(c)(3) of the Internal Revenue Code. The Historical Society was initially formed in 1954 and since 1966 has operated a history museum in Micke Grove Regional Park under an agreement with the County of San Joaquin. History of Historical Society
The Museum was initially accredited by the American Association of Museums (AAM) in 1973 and has retained that status after subsequent reviews. AAM accreditation is noteworthy—only 5% of American and California museums are fully accredited.
The Historical Society and Museum maintains for the County of San Joaquin a collection of more than 50,000 historic objects representative of the history of the region, as well as historical archives.
The Historical Society and the County maintain the grounds of the 18.5 acre Museum campus, plus eight exhibition buildings, administrative and collections storage space, a workshop building with maintenance and restoration shops, a small gift shop building, a barn-like education support building, and a restroom building.
The Historical Society and Museum is governed by a Board of Trustees elected by the members of the Society. A handful of Society employees focus their efforts on collections conservation and management, facilities maintenance and security, educational programs and visitor services, administration, and publications.
The Historical Society relies heavily on volunteers. The volunteers who conduct the Museum’s educational programs and services for schoolchildren are called “docents” (from Latin “to teach”) and the Docent Council is organized to train and maintain this critical workforce. Other volunteers include a group that restores historic agricultural equipment, and “Friends of the Museum” volunteers who do a variety of support tasks.
