Librarysse

Librarysse is a library management system designed to support libraries' day-to-day operations and digital resource access. It aims to unify cataloging, circulation, acquisitions, and user management under a modular, open-source platform. The system targets public, academic, and special libraries and seeks to integrate physical and digital collections through a single interface.

Key features include cataloging support for multiple metadata standards (MARC21, Dublin Core, MODS), circulation with patron holds and fines, acquisitions workflows, and robust reporting. The discovery layer provides a unified search across holdings and digital items, while the system offers APIs and webhooks to connect with external systems such as discovery interfaces, authentication providers, and digital lending platforms. It supports interlibrary loan workflows, item-level restrictions, and configurable permissions. The platform includes a responsive web interface and mobile apps for patrons, staff interfaces, and administrative dashboards.

Librarysse uses a modular architecture with a central ILS core, separate modules for cataloging, circulation, acquisitions, and digital access, and optional add-ons for digitization workflows and repository integrations. It is designed to be deployed on-premises or in the cloud and supports containerized deployment with Docker and orchestration with Kubernetes. Data storage typically relies on relational databases, with support for backups and high availability; metadata normalization and quality controls are emphasized.

Development is community-led, with contributions from libraries, developers, and vendors. The project is released under an open-source license and maintained through public repositories, issue trackers, and a documentation site.

Users report improved workflow efficiency, and the system aims to provide a sustainable alternative to proprietary library systems, emphasizing open standards and interoperability.
