The move from the mainframe based LMS (Library Management System) to a predominantly client-server/SQL environment promised ease of integration of services such as course electronic reserve with the traditional core LMS services: cataloging, acquisitions, circulation, and OPAC. However, a variety of factors have conspired to slow the pace of this much desired assimilation. Because they have existed so long outside of the Library Management System, course electronic reserve processes have developed according to local requirements without the limits imposed by monolithic, and often inflexible, Library Management Systems. Complicating the matter, the recent development and implementation of Course Management Systems such as Prometheus, WebCT, Blackboard, and Sakai have raised the question as to whether course electronic reserve should “live” in the OPAC or the CMS. Less controversial is the assertion that no matter where they reside they should be easily and seamlessly accessible from both.
