Functions of the Archive
The function of the Archive is to preserve and protect Tuolumne County’s written history. The Archive is named in honor of Carlo M. De Ferrari, a third generation Tuolumne County native son and the official historian of Tuolumne County, a title bestowed in 1972 by the Tuolumne County Board of Supervisors in recognition of his extensive knowledge of local history and his dedication to its preservation.

The governing body of the Carlo M. De Ferrari Archive is the Tuolumne County Board of Supervisors. The Board of Supervisors designated the Assessor-Recorder as the County Archivist. The county archivist oversees general administration of the Archive. The records manager supervises daily operations. All records accepted for preservation in the Archive must have an historical connection to official county governmental business.

Volunteers from the Tuolumne County Historical Society and the Tuolumne County Genealogical Society accession records. The Archive is largely dependent on these volunteers to perform its mission.
