What Sonoma County Library does

Sonoma County Library is a public library system operated as a Joint Powers Authority under California law, serving all residents of Sonoma County with free access to physical collections, digital resources, and community programming. Founded in 1975, the system operates 19 locations across the county, including 12 regional/community libraries, two specialized facilities (the Sonoma County Wine Library and the History & Genealogy Library), the BiblioBus mobile service, and periodic service points in remote areas such as Sea Ranch. Headquarters and the Central Santa Rosa Library anchor the network, which spans cities from Cloverdale in the north to Petaluma in the south.

The library's technical platform integrates a BiblioCommons online catalog with interlibrary loan via the LINK+ consortium and a digital eLibrary aggregating more than two dozen third-party services, including OverDrive/Libby for eBooks and eAudiobooks, hoopla for digital media, Kanopy for streaming video, PressReader for newspapers and magazines, NewsBank, EBSCO, Ancestry Library Edition, Tutor.com, LinkedIn Learning, Coursera, Mango Languages, and Creativebug. Digital preservation is supported by the Quartex collections platform hosting local history, wine history, photographs, and oral histories, alongside a Playback Memory Lab for digitizing legacy media. Custom-built services include the SonomaFi Connect mobile WiFi hotspot kits (15 units deployed for community outreach), BiblioBox self-service pickup lockers, a mobile app, 3D printing, a Connected Chromebook lending program, and the Sonoma County Library Sound Studios. Specialized assets span the Wine Library, History and Genealogy Library, Petaluma History Room, and a Local History Index for researching Sonoma County people, places, and events.

Funding flows primarily through Measure Y library sales tax revenues, supplemented by grants (notably a $41,460 IMLS grant that underwrote SonomaFi Connect) and donations channeled through Friends of the Library organizations. All services are free to county residents with a library card, including physical borrowing, digital downloads, streaming, database access, computer use, room reservations, and equipment lending. Distribution extends beyond fixed branches to BiblioBus routes, SonomaFi Connect community outreach events (78 events serving 2,000+ residents in 2022-2023), and active programming for early literacy (Storytime, 1000 Books Before Kindergarten, Summer Reading Challenge), teens (Teen Space, Read Three Get One Free), adults (Career Online High School, Adult Literacy tutoring, Lawyers in the Library), the Hispanic/Latino community (Spanish-language resources, Mango Languages), and seniors (outreach events with technology assistance). The system is governed by a Library Commission and operated by approximately 51-100 employees across all branches and administrative functions.
