Koha

Koha provides a complete integrated library system that manages acquisitions, circulation, cataloging, label printing, and offline circulation when network access is unavailable. Its modular architecture lets libraries handle the full workflow of acquiring, cataloguing, and lending materials while maintaining detailed records and reports. The system is designed to be self‑hostable and runs without subscription fees, offering a free‑tier option under the GPL‑3.0 license.

The software is targeted at libraries of all types and sizes that need a scalable, open‑source solution for day‑to‑day operations. It is maintained by a community of volunteers, support companies, and library sponsors, and includes tools for developers such as a handbook, bug tracker, and contribution guidelines. Regular releases are published, demonstrating ongoing development and stability.

Koha’s distinctiveness lies in being the world’s first free and open‑source ILS, providing enterprise‑class features without proprietary constraints. Its extensive release schedule and community‑driven governance support continuous improvement and adaptability to diverse library environments.
