Title

Time for new OPAC initiatives : an overview of landmarks in the literature and introduction to WordFocus

Abstract

It is time to progress beyond the 'same old systems' approach to OPACs into an era that incorporates improvements in libraries' existing databases, embraces research results into the information seeking process, and makes fundamental improvements to OPACs by adding new databases. This approach should convert the frustrated users of today into the eager users of tomorrow's local library systems
