Abstract
The major attractions of building a Web based reference information system are described: software is virtually 'free'; required training is minimal; systems can be accessed by a variety of platforms; and reference librarians around the world are able to share their expertise. Discusses these points in the context of the evolution of reference information file systems and describes a prototype to show how to construct a basic Web based system
