What Peninsula Library System does
Peninsula Library System (PLS) is a non-profit cooperative library consortium established in 1971, headquartered in Burlingame, California, and serving the residents of San Mateo County. It comprises 34 member libraries — 31 public libraries across the county's municipalities (including Atherton, Belmont, Daly City, Redwood City, San Mateo, and South San Francisco) and three community college libraries (Canada College, College of San Mateo, and Skyline College). PLS provides free public access to physical and digital materials, research databases, public computers, and community programming to anyone holding a PLS library card, with no direct user fees.
The consortium operates on a shared technology stack built primarily on third-party platforms. The Sierra Web Catalog by Clarivate (delivered via the legacy WebPAC PRO interface and a modern Sierra front-end) powers unified search and account management across all member libraries. A BiblioCommons layer adds social features including user ratings, reviews, and custom booklists. Digital lending is delivered through OverDrive for eBooks and eAudiobooks, supplemented by Follett Software for specialized collections such as the California Missions eBooks. EnvisionWare provides cross-branch PC reservation, ShoutBomb delivers SMS notifications, and ContentCafe and Syndetics enrich catalog records with reviews and book jacket imagery. Mobile apps are available on iOS and Android, and the consortium operates ancillary services including the Discover & Go cultural pass program and the SMC Connect community-resources directory.
PLS is funded through member jurisdiction contributions and public tax allocations rather than commercial pricing, with services provided free of charge to county residents. The organization is governed by an Administrative Council drawn from its member libraries and operates under California public library law. The Classic Catalog interface is scheduled for retirement on November 1, 2026, with users being migrated to the BiblioCommons and Sierra-based catalog experiences. PLS has 101-250 employees and does not publicly disclose revenue or financial figures.
