- Abstract
- Describes a research project, at Middlesex Polytechnic, aimed at evaluating a front end thesaurus to navigate users through subject searches in on-line catalogues (OPACs). The British Library sponsored project involves the adaptation of the RIN file, used for thesaurual control of the British National Bibliography (BNB), to be used as a front end for a MARC data base with PRECIS subject indexing
