Shared Integrated Library System (SILS)

In 2013 the Alliance partnered with Ex Libris to implement Alma and Primo as the Shared Integrated Library System (SILS) and discovery solution for all members. The SILS has a Network Zone (NZ) for shared cataloging and peer-to-peer configuration for Resource Sharing, referred to as “Summit.”


Alma is “a secure, scalable end-to-end library software system (ILS) for managing the acquisition, sharing, cataloging, and use of all kinds of resources” (Alma Overview, Ex Libris Knowedge Center).


Primo is the discovery layer over Alma. The Members page contains links to each Alliance institution’s Primo instance.

  • Primo Documentation: Documentation by the Discovery & User Experience program.
  • Primo VE Resources: Starting October 2021, the Alliance will migrate from the Primo Back Office (PBO) architecture to Primo VE.

Ex Libris Users of North America (ELUNA)

ELUNA is the user community for Ex Libris customers in the Americas, while the International Group of Ex Libris Users (IGeLU) represents customers in other countries. Once a year, the Alliance submits votes to ELUNA/IGeLU on proposed enhancements to Alma and Primo based on the recommendations of the Alma Enhancements Project Group and Primo Enhancements Project Group.

See Ex Libris Users of North America (ELUNA) for a list of representatives who submit votes for their institutions.
