About the Collections

The Sonoma County Library, through our Sonoma Heritage Collections, seeks out, acquires and makes digitally accessible, materials in all formats to illuminate Sonoma County history and culture. The Heritage Collections exhibit the extensive collection of historical photographs and texts gathered in the the Library's History & Genealogy Library, Petaluma History Room and Sonoma County Wine Library, as well as archival collections located in the Sonoma County Archives, and our partners, the Sonoma County Bar Association, Western Sonoma County Historical Society and Sonoma County Fair. We encourage you to explore the Heritage Collections through the individual collections and through the 24 Heritage themes. Please see the SHC About page for more information.
