Evolution of the Research Libraries Information Network

The Research Libraries Group, Inc. (RLG), a nationwide consortium of research institutions, operates the Research Libraries Information Network (RLIN), an information system and communications network that supports RLG's cooperative programs as well as the technical processing and public services requirements of research libraries. Changes in communications technology, in the regulatory environment, and in user requirements have led RLG to redesign its communications network. The goals, topology, hardware, software and protocols, deployment, and related matters are discussed. Sidebars address current RLIN communications technology and the integrated RLIN network.
