The Inter-Search system is a web-based service that has attracted subscriptions from over 400 libraries across separate special library groups over the last ten years.  Its success rests on distributing the workload among the participating libraries and providing a very low cost infrastructure for participating libraries.  Libraries use the service on an annaul subscription basis.
