- Abstract
- Advances in computer and communication technology technology have had an important impact on OPACs. The client server architecture model, the Internet, protocols, and standards such as Z39.50 have resulted in newly designed interfaces which reduce syntactic and semantic knowledge required to conduct effective online searches. Experimental OPACs have been developed in an attempt to assist users in conceptual transformation of their information needs into searchable queries. These experiments are based primarily on determining users' behaviour at the OPAC terminal, which needs much further study. Other non traditional models for storing and retrieving information should be considered to create an intuitive OPAC
