*FOLIO (Future of Libraries Is Open)* is a community-driven, open-source library services platform (LSP) that is transforming the library operations and technology landscape. Moving beyond the limitations of traditional, proprietary Integrated Library Systems (ILS), FOLIO offers a modern, flexible, and extensible solution built for the digital era. FOLIO is designed to support traditional library operations (like cataloging, circulation, and acquisitions) while enabling innovation through modular architecture. Unlike monolithic ILS systems, FOLIO is built as a collection of apps that work together through a shared platform. Developed collaboratively by libraries, vendors, and open-source developers—including major contributions from EBSCO and Index Data—FOLIO represents both a system and a community-driven ecosystem. In recent years, libraries have been navigating a rapidly evolving landscape shaped by digital transformation, growing user expectations, and the need for more flexible, open, and interoperable systems. Traditional integrated library systems (ILS) have struggled to keep pace with these demands. Enter FOLIO—an open-source Library Services Platform (LSP) that is redefining how libraries manage resources, workflows, and services. *Keywords:* FOLIO, Library Services Platform (LSP), Integrated Library System (ILS), Library Software, Future of Libraries Is Open, Open-Source Software (OSS), Library Management System *Source: https://www.librarianshipstudies.com/2025/11/folio-open-source-library-servi... <https://www.librarianshipstudies.com/2025/11/folio-open-source-library-services.html> * *Contents* - Key Features and Capabilities 1.
