Title
Implementing NOTIS keyword/Boolean searching : a case study
Source
Cataloging and classification quarterly. 10(1989) nos.1/2, S.125-140

Abstract
Contribution to a thematic issue devoted to subject control in on-line catalogues. Keyword searching with Boolean operators was impossible in the traditional on-line catalogue and its promised benefits in on-line systems are not yet clear. Reports on a survey undertaken at Brigham Young University library, Utah, which investigated this issue when the library was selected as a test site for keyword searching in the NOTIS on-line catalogue. Results of the survey were mixed. While keyword searching will require increased computer capacity for unstricted use, students, though content with the new tool, are not adept at using its sophisticated features and will require much more training than for the basic NOTIS on-line catalogue.
