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.

In addition to photos and documents, the archives also collects personal stories. Since we are currently living through a world changing event, we've put together a survey to find out just what how the residents of Placer County feel about the Pandemic. Make your voice part of history by filling out our online Pandemic 2021 Survey. The historians of 2120 thank you in advance.
