Title

¬The design of subject access elements in Online Public Access Catalogs

Source

International Classification. 17(1990) no.2, S.66-76

Year

Abstract

Experiences with retrieval in OPACs suggest that there are major problems for users of such systems, such as choosing the correct subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Using a typology of users' questions it is demonstrated which requirements must be met by successful on-line subject access
