Abstract

Attempts to gauge whether syndetic structure, the cross reference system long regarded as an integral component of the controlled vocabulary which predominates as the indexing framework for online subject searching, still has a role to play in assisting end users in their information quests. To this end, examines a number of existing and proposed enhancements to OPACs by means of a literatur review. These include: Boolean and keyword searching; online browsing; artificial intelligence; classification clustering; and hypertext. Discusses Dervin's sensemaking theories and methodologies
