    Abstract
    The concept of relevance has played a major role in the evaluation of information retrieval and its research without much consideration of users. While methodological deficiencies have been noted and criticized, the study of relevance is still suffering from much discussion of alternative methods. This article discusses the need to develop the concept of user-based relevance for the benefit of users and for the meaningful development of future research in information retrieval. Some of the characteristics of users' criteria of relevance are examined from the literature. The use of a qualitative research approach is suggested as an alternative methodology for studying user-based relevance along with a discussion of the essential characteristics and the core philosophical assumptions underlying the inquiry paradigm

    Abstract
    Examines the degree and extent of bibliographic data of selected electronic journals in the national bibliographic utilities, and the means to provide access to them at individual libraries. The study was limited to networked electronic journals, and each title was searched in OCLC to determine its availability in a national database as well as its holdings libraries

    Abstract
    Experimental research in information retrieval (IR) depends on the idea of relevance. Because of its key role in IR, recent questions about relevance have raised issues of methododlogical concern and have shaken the philosophical foundations of IR theory development. Despite an existing set of theoretical definitions of this concept, our understanding of relevance from users' perspectives is still limited. Using naturalistic inquiry methodology, this article reports an emprical study of user-based relevance interpretations. A model is presented that reflects the nature of the thought process of users who are evaluating bibliographic citations produced by a document retrieval system. Three major categories of variables affecting relevance assessments - internal context, external context, and problem context - are idetified and described. Users' relevance assessments involve multiple layers of interpretations that are derived from individuals' experiences, perceptions, and private knowledge related to the particular information problems at hand
