The Sonoma County Library was formed in 1975 through a Joint Powers Agreement signed by representatives of the cities of Healdsburg, Petaluma, Santa Rosa, and Sonoma as well as the County of Sonoma. The Library is the result of this collaborative agreement, existing as a “Joint Powers Agency” separate from the parties to the agreement.
Today, our county-wide library system serves approximately 495,000 residents in the cities, towns and communities of Cloverdale, Cotati, Guerneville, Healdsburg, Petaluma, Rohnert Park, Santa Rosa, Sebastopol, Sonoma and Windsor. Through library services and programs at our 14 locations, online, and through targeted outreach, we embrace our mission to bring information, ideas, and people together to build a stronger community.
We are known nationally for our innovation and locally for our connection to our residents and communities. We are a community hub where learning, the arts, technology, and people intersect and thrive. Our staff is known throughout the community for being engaged, empowered, energized, and ubiquitous!
