    Abstract
    Library users continue to experience difficulty in using the online catalog, particularly in the area of subject access. This project describes a test of a new design for subject access to online catalogs. The new design requires a wide range of subject searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Is the performance of search trees superior to subject searching approaches chosen at random? This project is geared to make that determination

    Abstract
    n this article, we report on the first large-scale study of end-user understanding of subject headings. Our objectives were to determine the extent to which children and adults understood subdivided subject headings and to suggest improvements for improving understanding of subject headings. The 1991 Library of Congress Subject Subdivisions Conference suggested standardizing the order of subject subdivisions for the purpose of simplifying subject cataloging, which served as the impetus for the study. We demonstrated that adults understood subject headings better than children; however, both adults and children assigned correct meanings to less than half of the subject headings they examined. Neither subject heading context nor subdivision order had an effect on understanding. Based on our findings, we challenge the library community to make major changes to the Library of Congress Subject Headings system that have the potential to increase end-user understanding of subject headings.

    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
    This article describes the findings of a research project that tested a new subject-access design in an experimental online catalog that had a wide range of subject-searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Library users at 2 academic libraries searched this experimental catalog for topics of their own choosing, judges the usefulness of retrieved titles, and answered post-search questions about their searching experiences. Mixed results from a quantitative analysis (i.e., precision scores) were supplemented with the more conclusive results from a qualitative analysis (i.e., failure analysis). Overall, analyses demonstrated that the new subject-access design that featured search trees was more effective in selecting a subject-searching approach that would prooduce useful information for the subjects users seek than users would select on their own. The qualitative analysis was especially helpful in providing recommendations for improving specific subject-searching approaches to increase their effenciency, increase user perseverance, and encourage browsing. It also suggested enhancements to the new subject-searching design to enable systems to respond to the wide variety of user queries for subjects

    Abstract
    The first studies of online catalog use demonstrated that the problems of too many and too few retrievals plagued the earliest online catalog users. Despite 15 years of system development, implementation, and evaluation, these problems still adversely affect the subject searches of today's online catalog users. In fact, the large-retrievals problem has grown more acute due to the growth of online catalog databases. This paper explores the use of library classifications for consolidating and summarizing high-posted subject searches and for handling subject searches that result in no or too few retrievals. Findings are presented in the form of generalization about retrievals and library classifications, needed improvements to classification terminology, and suggestions for improved functionality to facilitate the display of retrieved titles in online catalogs

    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
    In an interview with Robert P. Holley, Karen M. Drabenstott provides a history of a professional career that has focused on subject access to information. Since her early work with Pauline Cochrane, she has strongly supported enhanced bibliographic records as a way to improve user access in the online catalog. Her Dewey Decimal Classification Online project showed that the classification offers increased subject retrieval. Her current projects include improved strategies for Web searching and multimedia literacy including subject access.

    Abstract
    Recognises the limitations of the existing files of Library of Congress name and subject authority records for indirect geographic subdivision. Makes recommendations for enhancements to existing authority records, which would enable online systems to assist in subject heading formulation and verify, with limited assistance by human intermediaries, whether geographic subdivision is authorized for use with a particular main heading and whether the correct form of indirect geographic subdivision is authorized for use with a particular main heading and whether the correct form of indirect geographic subdivision is given. A study of subdivided subject headings in a large bibliographic data base forms the basis of the recommendations

    Abstract
    Describes the comparative approach to system evaluation used in this research project which delegated the administartion of an online retrieval test to an experimental online catalogue to produce data for evaluating the effectiveness of a new subject access design. Describes the methods enlisted to sort out problem test administration, e.g. to identify out-of-scope queries, incomplete system administration, and suspect post-search questionnaire responses. Covers how w the researchers handled problem search administrations and what actions they would use to reduce or eliminate the occurrence of such administrations in future online retrieval tests that delegate control of retrieval tests to online systems

    Abstract
    Describes a study to investigate end user understanding of subdivided subject headings in their current form and in the form proposed by the first recommendation of the Library of Congress Subject Subdivisions Conference. The impetus for this study was a charge by the Subject Analysis Committee of the ALA to respond to the first recommendation of the LC Subject Subdivisions Conference that proposed standardizing the order of subject subdivisions. Questionnaires bearing subdivided subject headings in the 'current' form and in the form proposed were distributed to users and professional cataloguers who were asked for the meaning of individual headings. The end users' responses to cataloguers' responses were compared to determine end users' level of understanding of subdivided subject headings. An analysis of end user interpretations demonstrated that they interpreted the meaning of subject headings in the same manner as cataloguers about 40% of the time for 'current' forms of subject headings and about 32% of the time for 'proposed' forms of subject headings. Concludes with specific recommendations about the first recommendation of the LC Subject Subdivisions Conference and general recommendations about increasing end user understanding of subdivided subject headinbgs

    Abstract
    Using subject headings for Online Retrieval is an indispensable tool for online system desingners who are developing new systems or refining exicting ones. The book describes subject analysis and subject searching in online catalogs, including the limitations of retrieval, and demonstrates how such limitations can be overcome through system design and programming. The book describes the Library of Congress Subject headings system and system characteristics, shows how information is stored in machine readable files, and offers examples of and recommendations for successful methods. Tables are included to support these recommendations, and diagrams, graphs, and bar charts are used to provide results of data analyses.
