ELUNA works with its sister organization IGeLU (International Group of Ex Libris Users) which represents over 400 institutions in over 30 countries. IGeLU promotes the information sharing among Ex Libris product users on solutions, innovations, documentation, and resources.
ELUNA and IGeLU work together to support product enhancement cycles based on a formal agreement with Ex Libris. The two organizations also collaborate in representing the interests of Ex Libris products through working groups, with some working groups being jointly run (like the Content WG) and some being ELUNA-only (like the ELUNA Primo WG).
