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

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

Surfing the World Wide Web used to be cool, dude, real cool. But things have gotten hot - so hot that finding something useful an the Web is no longer cool. It is suffocating Web searchers in the smoke and debris of mountain-sized lists of hits, decisions about which search engines they should use, whether they will get lost in the dizzying maze of a subject directory, use the right syntax for the search engine at hand, enter keywords that are likely to retrieve hits an the topics they have in mind, or enlist a browser that has sufficient functionality to display the most promising hits. When it comes to Web searching, in a few short years we have gone from the cool image of surfing the Web into the frying pan of searching the Web. We can turn down the heat by rethinking what Web searchers are doing and introduce some order into the chaos. Web search strategies that are tool-based-oriented to specific Web searching tools such as search en gines, subject directories, and meta search engines-have been widely promoted, and these strategies are just not working. It is time to dissect what Web searching tools expect from searchers and adjust our search strategies to these new tools. This discussion offers Web searchers help in the form of search strategies that are based an strategies that librarians have been using for a long time to search commercial information retrieval systems like Dialog, NEXIS, Wilsonline, FirstSearch, and Data-Star.

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.

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

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

Reports results of a study to examine the performance of online catalogue searches involving personal names and to recommend improvements to the basic system approach to soliciting user queries and searching for them. The research questions addressed in the study wre: how online systems can chose searching approaches on their own that are likely to produce useful retrieval; how online systems solicit queries from users; and how users respond to an experimental online catalogue that prompts them for the different elements of their personal name queries. Improvements include: the implementation of a new design for online catalogue searching that features search trees; new methods for soliciting user queries bearing personal names; and enlisting the participation of online catalogue users in the evaluation of system prompts, instructions, and messages that request input from them

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.
