Summon is Ex Libris's standalone library discovery layer, searching a library's print, electronic, and digital collections through a single index.
Summon is a standalone library discovery service from Ex Libris that gives a library's patrons one search box across print holdings, licensed electronic subscriptions, open-access sources, and institutional repositories. It runs on the Central Discovery Index and the 360 Knowledgebase, and its provider-neutral design lets it sit in front of almost any library management system instead of one matched platform.
The offering competes in the market for library discovery layers, the search systems that academic, research, and special libraries place above their catalogs and database subscriptions. Its differentiation is deployment flexibility: a library can adopt it without the integrated management platform its larger sibling requires, which appeals to institutions that want a modern discovery experience while keeping their existing systems.
