Title
User practices in keyword and Boolean searching on an online public access catalog
Source
Information technology and libraries. 11(1992) no.3, S.210-219
Year

Abstract
Keyword and Boolean searching modes are now becoming more commonly available on online public access catalogs, and questions have arisen regarding their use by library patrons. How difficult do users perceive these searches to be? Do those who use them tend to rely on them all the time to the exclusion of all other methods? This study attempts to provide answers to these questions in the context of an academic library that uses the Northwestern Online Total Integrated System Online catalog
