    Abstract
    2 experiments investigated how textual factors influence the perception of bibliographical records. Subjects in the 1st experiment browsed indexes for the subject discriptor associated with the displayed record. Results showed that topical and broader descriptors are matched to records more easily than narrower descriptors. In the 2nd experiment, subjects ranked the relevance of descriptors for a bibliographic record. The interaction of 3 textual factors are reported: a semantic distance, direction up or down a generic tree of descriptors; and term overlap. Both experiments found that relevance perceptions degraded systematically with semantic distance, but the rate of degradation was different for top and bottom records. Term overlap modified these effects

    Abstract
    Reports 2 experiments that investigated the semantic distance model (SDM) of relevance assessment. In the 1st experiment graduate students of mathematics and economics assessed the relevance relationships between bibliographic records and hierarchies of terms composed of classification heading or help menu terms. The relevance assessments of the classification headings, but not the help menu terms, exhibited both a semantic distance effect and a semantic direction effect as predicted by the SDM. Topical subject expertise enhanced both these effects. The 2nd experiment investigates whether the poor performance of the help menu terms are an experimental design artifact reflecting the comparison of terse help terms with verbose classification headings. In the 2nd experiment the help menu terms were compared to a hierarchy of single word terms where they exhibited both a semantic distance and semantic direction effect

    Abstract
    Relevance assessments of topical descriptors for bibliographic records were gathered for 2 dimensions: a vertical conceptual hierarchy of broad to narrow descriptors, and a horizontal linkage of related-terms spanning 3 descriptors. The data were analyzed for a semantic distance and semantic direction effect as postulated by the Semantic Distance Model (SDM). The vertical conceptual hierarchy exhibited a strong SDM effect. The horizontal linkages of related terms exhibited an attenuated semantic distance effect. Results showed that the horizontal semantic distance to nonrelevance is greater for semantically narrow records than for semantically broad records. Explains the difference by introducing the construct of the stride length of conceptual semantic steps. Horizontal semantic steps at the bottom of conceptual hierarchies are postulated to have smaller and more uniform stride lengths than horizontal horizontal semantic steps at the top of the conceptual hierachies. Relevance assessments in both dimensions were combined to visualize the relevance aura of bibliographic records. The aura for semantically narrow bibliographic records was found to be larger than the aura for semantically broad records

    Abstract
    A citation analysis examined the 28 best articles published in JASIS from 1969-1996. Best articles tend to single-authored works twice as long as the avergae article published in JASIS. They are cited and self-cited much more often than the average article. The greatest source of references made to the best articles is from JASIS itself. The top 5 best papers focus largely on information retrieval and online searching

    Abstract
    Empirical analysis of relevance assessments can Illuminate how different groups of readdes perceive the relationship between bibliographic records and Index terms. This experiment harvested relevance assessments from two groups: engineering students (here after "engineers") and library school students ("librarians"). These groups assessed the relevance relationships between bibliographic records and Index terms for theee literatures: engineering, psychology and education. Assessment included the indexer-selected term (the topically relevant term) as well as broader, narrower and related terms. Figures 1-8 (pages 27-35) show these terms arranged as two-dimensional term domains. Positive relevance assessments plotted across the two-dimensional term domains revealed regular patterns, here called "relevance auras." A relevance aura is a penumbra of positive relevance, emanating from bibliographic records across a term domain of broader, narrower and related index terms. This experiment attempted to compare the relevance auras produced by engineers and librarians at both a macro and micro level of aggregatinn. Relevance auras appeared in data aggregating reader groups and literatures. Micro analyses of individual records, however, showed that relevance auras were ragged or did not develop. Agreement in relevance assessment appears an the individual term basis and often independently of the formation of a relevance aura.

    Abstract
    GOLDHORs challenge to librarianship to find invariant, universal relationships among library variables is discussed. Scientific problem solving is seen within the context of KUHNian science, and research in librarianship is consiedered as not having the characteristics of KUHNian science. The work of librarianship is analyzed as primariliy a discussion of values, or post hoc rationalization of event. It is concluded that library problem solving will not succeed until fundamental problems are addressed.
