Title
Controlled and uncontrolled vocabulary subject searching in an academic library online catalog
Source
Information technology and libraries. 10(1991), S.201-211
Year
1991
Abstract
An analysis of transaction logs from an academic library online catalog describes instances in which users have tried both controlled and uncontrolled (title keyword) vocabulary subject access during the same search session. Eight hypotheses were tested. Over 6.6% of all dial access search sessions contained both methods of subject access. Over 58% of the isolated sessions began with an uncontrolled vocabulary attempt. Over 76% contained only one vocabulary shift. On average, user persistence was greater during controlled vocabulary search logs, but search output was greater during uncontrolled vocabulary search logs. Several recommendations regarding catalog design and instruction are made.
