Abstract
In the present environment of database searching, the research library user who is familiar with the concept of keyword searching with Boolean logic capabilities very often uses this same strategy in the online catalog rather than looking up the established form of the heading listed in 'Library of Congress Subject Headings' and 'Library of Congress Name Authorities'. Questions that needed to be addressed were: does keyword searching provide a satisfactory substitute for searching by the authorized heading, and what kind of service or disservice do libraries to their users when keyword searching is the only strategy tried? This study determined how many of of the nonauthorized headings listed as cross references in an authority system could be found in the bibliographic record. It also examined the necessity for truncation of the keyword terms derived from the nonauthorized heading. A weighted system measured the frequency with which individual MARC fields provided matches for the keywords. The results of this study lead to recommendations for maximizing search strategies
