Title
¬The next generation of online public access catalogs : a new look at subject access using hypermedia
Source
Cataloging and classification quarterly. 13(1991) nos.3/4, S.103-132
Year
1991
Abstract
Current online catalogs have problems providing reasonable subject access, often resulting in searches with too few or too many hits. These problems can be improved by enhancing MARC records, building semantic networks through cross-references, and linking subject headings to classification numbers. This paper describes a pilot project to design a hypertext search engine using these principles
