    Abstract
    The impetus for a large-scale study on subject heading understanding was a recommendation of the Library of Congress (LC) Subject Subdivisions Conference that suggested standardizing the order of subject subdivisions for the purpose of simplifying subject cataloging. This paper focuses on unexpected large-scale study findings about multiple meanings for subdivided subject headings and the effects that changes of meaning for different orders of subdivisions had on the meanings that end users and librarians provided to subdivided subject headings. Findings about changes of meaning in subdivided subject headings did not dissuade the authors regarding their recommendation that the library community adopt a standard order of subdivisions. The authors also give suggestions for additional studies of subject heading understanding that build on this one.

    Abstract
    This paper recognizes the limitations of the existing file of Library of Congress (LC) subject authority records for subject heading assignment and validation. it makes recommendations for a new file of machine readable authority records for period subdivisions and for enhancements to the existings file of subject authority records. Recommended changes would enable online systems to assist in subject heading formulations and verify, with limited assistance by human intermediaries, the individual components of subdivided headings. The recommendations are timely in view of changes to the forms of period subdivisions that the Library of Congress is studying to facilitate the display of period subdivisions in chronological order. The availability of machine-readable authority records for most period subdivisions would enable online systems to automatically make changes to the forms of period subdivisions in bibliographic records using cross references for previously-used forms in the autority records for the new forms. The paper also discusses issues arising from an enhancement of the existing controlled system of period subdivision. A study of subdivided subject headings in a large bibliographic database forms the basis of the recommendations

    Abstract
    Introducess a new approach to display retrieved subject headings in subject searching designed to encourage users to browse bibliographic information. Emphasizes the importance of the exact display approach by showing how many user queries could be candidates for this approach, demonstrates an implementation of the exact-display approach in an experimental online catalogue. End user experiences gives opportunities to make recommendations for enhancing the original design of the exact display approach so that future implementations of this approach in operational online catalogues are responsive to the needs of online catalogue users

    Abstract
    Subject queries were extracted from 3 universities' online catalogues and analysed to determine the extend to which they matched subject headings in the LCSH. Computer analyses show that nearly 25% of the subject queries entered by online catalogue users are exact matches of LCSH. Yet, manual analyses show that, even though a user matches or closely matches LCSH-mr, the citations retrieved by this vocabulary are not necessarily satisfactory. Sometimes the closest LCSH-mr is not at all pertinent to a user's topic of interest. This study presents reasons why close matches of LCSH-mr are not always satisfactory and suggests approaches to finding the best matches of the catalogue's controlled vocabulary

    Abstract
    Search trees are sets of paths with branches or choices that enable systems to carry out the most sensible search approaches at each stage of searches. Report results of a research project, undertaken at Michigan University, which aimed to identify characteristics of the most difficult user queries and recommend enhancements to the new subject searching design to enable it to produce useful retrievals in response to the wide variety of queries users pose to online catalogues. Online catalogues governed by search trees are more effective than the users themselves in selecting subject searching approaches and the enhanced search trees described and tested enlist subject searching approaches that are not typical of the functionality of operational online catalogues. Concludes that design and development is required to upgrade existing online catalogues with search trees and new subject searching functionality to be successful in responding with useful retrievals to the most difficult user queries

    Abstract
    Reports results of 2 separate but related projects to study the influence of spelling errors (misspellings), made by searchers, on the subject searching of online catalogues and to suggest ways of improving error detection systems to handle the errors that they detect. This involved the categorization of user queries for subjects that were extracted from the online catalogue transaction logs of 4 USA university libraries. The research questions considered: the prevalence of misspellings in user queries for subjects; and how users respond to online catalogues that detect possible spelling errors in their subject queries. Less than 6% of user queries that match the catalogue's controlled and free text terms were found to contain spelling errors. While the majority of users corrected misspelled query words, a sizable proportion made an action that was even more detrimental than the original misspelling. Concludes with 3 recommended improvements: online catalogues should be equipped with search trees to place the burden of selecting a subject the system instead of the user; systems should be equipped with automatic spelling checking routines that inform users of possibly misspelled words; and online catalogues should be enhanced with tools and techniques to distinguish between queries that fail due to misspellings and correction failures. Cautions that spelling is not a serious problem but can seriously hinder the most routine subject search

    Abstract
    User studies demonstrate that nondomain experts do not use the same information-seeking strategies as domain experts. Because of the transformation of integrated library systems into Information Gateways in the late 1990s, both nondomain experts and domain experts have had available to them the wide range of information-seeking strategies in a single system. This article describes the results of a study to answer three research questions: (1) do nondomain experts enlist the strategies of domain experts? (2) if they do, how did they learn about these strategies? and (3) are they successful using them? Interviews, audio recordings, screen captures, and observations were used to gather data from 14 undergraduate students who searched an academic library's Information Gateway. The few times that the undergraduates in this study enlisted search strategies that were characteristic of domain experts, it usually took perseverance, trial-and-error, serendipity, or a combination of all three for them to find useful information. Although this study's results provide no compelling reasons for systems to support features that make domain-expert strategies possible, there is need for system features that scaffold nondomain experts from their usual strategies to the strategies characteristic of domain experts.
