As a part of the Museums Division, the Placer County Archive and Collections Facility shares the division's mission to preserve the county's rich historic and cultural legacy.
Both the Collections as well as the Archives are collectors of private collections which are held in the public trust for the benefit of humanity. While the Collections side cares for three-dimensional artifacts, the Archive maintains extensive collections of photographs, maps, oral histories, newspapers, and private manuscripts while also serving as the official repository for historic records generated by the County of Placer since the county was established in 1851.
The Placer County Archives has embarked on a new journey to make digitized archival material accessible to the public using our Archives Online Database.
Our extensive photo collection stretches all the way back to the dawn of photography because of people donating their personal photos. Be a part of history by donating your photos. Historic or modern, we're interested to see what you have. Our online photograph submission page is the quickest way to donate your pictures that capture the area's history.
