Research, Collections & Artifact Storage
About the Center
In addition to the thousands of photos and objects on display in our museums, we are also in charge of keeping tens of thousands more safe and organized. The Archives and Research Center is in charge of photos, records, and oral histories while Collections takes care of three dimensional artifacts.
The Placer County Archives and Research Center is a repository for records generated by the county and a local history and genealogy research center. The collection of county records includes records dating from the beginning of the county in 1851. This includes over 30,000 photographs, as well as original bound copies of Placer County's first newspaper, the Placer Herald.
