Abstract

The OPAC has developed into an information providing tool capable of many varied tasks. Maps this development. Discusses the interface between the OPAC and the casual or inexperienced user and the expending use of networks. Surveays the growth of OPACs and shows that OPACs have developed a number of features from information retrieval. Assesses areas of further research
