Title
Relevance as an aid to evaluation in OPACs

Abstract
The relevance of retrieved documents or document descriptions has been a central measurement in the evaluation of information retrieval (IR) systems. Online public access catalogues (OPACs) are similar in many ways and so relevance should be an appropriate evaluation tool in measuring their performance. The development of relevance in evaluating IR systems is described and also the important differences between such systems and OPACs. Characteristics of the end-users of both systems are discussed with the conclusion that end-users' motivation and behaviour are as yet not fully understood. The implcations of this is that relevance is a central feature, but only one, of an OPAC user's overall information need
