RERO ILS is a next-generation open-source integrated library system developed in Switzerland by RERO+ and UCLouvain. It supports library networks and standalone libraries with modules for cataloging, acquisitions, circulation, search, and a public user interface, using an Invenio-based backend. The project comprises three GitHub repositories: rero-ils, rero-ils-ui, and rero-ebooks.

Key Features

  • Consortial model: designed for library networks with multi-organization configuration
  • Cataloguing and serial management: modern cataloging editor aligned with current standards and serials handling
  • Online catalog: public catalog with search, filtering, and configurable views; integration of ebooks and external databases
  • Circulation: checkout, check-in, requests, interlibrary loans, patron management, with a modern web interface
  • Data interaction: JSON bibliographic data with a Bibframe model and a powerful API to interact with the database

Use Cases

  • Manage library networks or multiple libraries within a single system
  • Provide a public online catalog for patrons with customizable views
  • Integrate external data sources such as ebooks and databases into the union catalog

Conclusion

RERO ILS aims to modernize library management with an open-source, configurable backend and a flexible frontend, enabling data exchange through APIs and a robust public interface. It is actively developed by RERO+ in collaboration with UCLouvain.
