(Cataloging) ILS = Integrated library system (FR : SIGB ou SGB)

Software (though in early incarnations a software/hardware combination) that provides housekeeping activities and management information in relation to library services.  Modules available can include cataloguing, acquisitions, circulation, OPAC, inter-library loans, periodicals control and reading list organization. It is becoming increasingly important that elements from these systems interoperate with wider institutional systems such as Portals and VLEs. Ifla
