What Open Library Foundation does

The Open Library Foundation (OLF) is a 501(c)(3) not-for-profit organization founded in 2016 and headquartered in Philadelphia, Pennsylvania. OLF serves as a fiscal sponsor and administrative infrastructure provider for a portfolio of open source projects serving the global library sector, offering legal, financial, banking, website hosting, and technical infrastructure services in lieu of developing proprietary technology. Its portfolio currently comprises eight major projects: FOLIO (library services platform), VuFind (discovery layer), Global Open Knowledge Base / GOKb (electronic resource data), OpenRS and Project ReShare (resource sharing), BitCurator Consortium (digital curation and preservation), Library Data Platform / LDP (analytics), Open Rules for Cataloging / ORC, and the Advanced Research Consortium / ARC (digital humanities). The foundation acts as a vendor-neutral "safe harbor," ensuring community ownership is separated from any single contributor or commercial sponsor's interests.

OLF monetizes its role through a four-stream membership model: sponsor memberships for commercial vendors at $1,000–$20,000 annual tiers (Bronze, Silver, Gold, Platinum) with marketing benefits and WOLFcon registrations; institutional memberships for academic libraries; individual memberships at $50 per year; and project memberships at $1,000+ annual base plus usage-based service fees for legal, banking, accounting, domain, and communications support. Donations supplement membership income and may be directed to specific projects or the general fund. The foundation's go-to-market is community-led: growth comes from member recruitment via the openlibraryfoundation.org website, a quarterly newsletter, LinkedIn, YouTube, RSS, and the rotating annual WOLFcon conference (e.g., Durham 2018, College Station 2020, Prague 2026). The software itself is distributed free of charge under open source licenses via project websites and GitHub repositories.

OLF is governed by a Board of Directors drawn from academic institutions, library consortia, and library technology vendors, including Stanford University (Board President Tom Cramer), EBSCO Information Services, Cornell University, MOBIUS Consortium, Florida International University, and ZBW – Leibniz-Information Centre for Economics. Operational leadership is lean, with named officers in the Treasurer, Secretary, Senior Program Officer, and Senior Operations Officer roles. The foundation reports no revenue, no headcount figure, and no external funding rounds; its scale signals are captured in the breadth of hosted projects, hundreds of libraries using VuFind globally, and WOLFcon attendance in the low hundreds.

Core offering

Open Library Foundation is a nonprofit foundation that provides governance, legal, financial, and operational support for open source software projects used by libraries, archives, and cultural heritage institutions. It hosts and stewards a portfolio of projects including FOLIO, VuFind, GOKb, OpenRS, Project ReShare, BitCurator Consortium, Library Data Platform, Open Rules for Cataloging, and ARC, and runs the annual WOLFcon community conference.

Product overview

The Open Library Foundation is a not-for-profit organization that serves as a fiscal sponsor and infrastructure provider for a portfolio of open source library technology projects. Rather than a single unified product, the Foundation hosts multiple distinct open source initiatives including FOLIO (library services platform), VuFind (discovery layer), Global Open Knowledge Base (electronic resource data platform), Project ReShare and OpenRS (resource sharing platforms), BitCurator Consortium (digital curation tools), Library Data Platform (analytics infrastructure), and Open Rules for Cataloging (cataloging standards). These projects share common infrastructure and governance under the Foundation but operate as independent open source communities with their own development trajectories and user bases.
