Abstract

The nature of a library's collections determines what kind of subject access to provide to those collections. The collections of the Cleveland Public Library serve both the recreational and research needs of a large urban population. The Cleveland Public Library uses Library of Congress Subject Headings to describe its collections. A study of subject searches entered by library patrons over the course of one week reveals several patterns among the types of subject headings used most frequently, reflecting the characteristics of the population served. Other topics discussed include subject access to fiction, juvenileliterature, and specialized collections

Abstract

The National Council of Teachers of Mathematics (NCTM) is an international organization which supports the teaching and learning of mathematics for children from Pre-Kindergarten through Grade 12. In the year 2000, the NCTM produced Principles and Standards for School Mathematics; a document that has become the basis for state and local mathematics curriculum standards across the United States. This article examines the key terms identified in the NCTM standards, identifies their equivalents in the ERIC Thesaurus and the Library of Congress Subject Headings, and makes recommendations to bring library subject headings closer to reflecting the language common to mathematics educators.

Abstract

This study is an examination of the overlap between author-assigned keywords and cataloger-assigned Library of Congress Subject Headings (LCSH) for a set of electronic theses and dissertations in Ohio State University's online catalog. The project is intended to contribute to the literature on the issue of keywords versus controlled vocabularies in the use of online catalogs and databases. Findings support previous studies' conclusions that both keywords and controlled vocabularies complement one another. Further, even in the presence of bibliographic record enhancements, such as abstracts or summaries, keywords and subject headings provided a significant number of unique terms that could affect the success of keyword searches. Implications for the maintenance of controlled vocabularies such as LCSH also are discussed in light of the patterns of matches and nonmatches found between the keywords and their corresponding subject headings.

Abstract

Library of Congress Subject Headings (LSCH), which celebrated its 100th birthday in 1998, is the largest cataloging and indexing language in the world for the indication of the topics and formats of books and similar publications. It consists of a controlled list of main headings, many with subdivisions, with a rich system of cross references. It is supported by the U.S. government, and undergoes systematic revision. In recent decades its managers have begun to confront challenges such as biased terminology, complicated syntax (how terms are put together to form headings), and effective displays in electronic media. Many suggestions have been made for its improvement, including moving to a fully faceted system.

"»Simplify your life«, heißt einer der großen Sachbuchbestseller der letzten Jahre. Dessen Quintessenz: In einer zusehends komplexer werdenden Welt sind Vereinfachungen (über)lebensnotwendig. Dies gilt für alle Lebensbereiche, in besonderem Maße aber für die Suche nach Informationen. Um Bibliotheksbenutzer an die von ihnen gewünschte Literatur heranzuführen, kann seitens der Bibliotheken sicher noch einiges an Vereinfachungsleistung erbracht werden - insbesondere dann, wenn der Benutzer sich bei der Suche nicht mit den Beständen seines nationalen Bibliothekssystems begnügt, sondern die Möglichkeit nutzt, weltweit online zu recherchieren. Eine Suche unter Zuhilfenahme von Titelstichwörtern bereitet heute nur wenig Kopfzerbrechen, ist aber oft unbefriedigend für die sachliche Suche. Leider gestaltet sich der hier deutlich zielführende Rückgriff auf Sacherschließungsdaten in der Praxis erheblich schwieriger. Der Benutzer ist mit einer Vielzahl unterschiedlicher Erschließungssysteme konfrontiert, die vielfach unverbunden nebeneinander existieren. Da die Bestände der weitaus meisten Bibliotheken heterogen erschlossen sind, müsste der Benutzer alle Erschließungsverfahren kennen und nacheinander anwenden, um sicherzustellen, dass ihm keine Informationen verloren gehen.
An diesem Punkt setzt das neue Projekt CrissCross an, das gemeinsam von der Deutschen Nationalbibliothek (DNB) und der Fachhochschule Köln betrieben und von der Deutschen Forschungsgemeinschaft (DFG) gefördert wird. CrissCross schafft Verbindungslinien zwischen einigen besonders verbreiteten und bewährten Erschließungsinstrumenten: Der deutschsprachigen Schlagwortnormdatei (SWD), den besonders im angloamerikanischen Raum verbreiteten Library of Congress Subject Headings (LCSH), der französischen Dokumentationssprache Répertoire d'autorité-matière encyclopédique et alphabétique unifié (Rameau) und der Dewey Decimal Classification (DDC) als dem international am meisten verbreiteten Klassifikationssystem. CrissCross kann dabei auf zwei wichtigen Vorgängerprojekten aufbauen. Hier ist zum einen das ebenfalls von DNB und der Fachhochschule Köln gemeinsam betriebene Vorgängerprojekt »DDC Deutsch« zu nennen. Bereits während dessen Laufzeit war deutlich geworden, wie vorteilhaft sich eine Anreicherung des DDC-Registers mit dem Schlagwortbestand der SWD auf die Klassifikationspraxis auswirken könnte. Genau dieser Schritt wird nun vollzogen, wobei sich die Projektarbeit auf die Sachschlagwörter konzentriert - kein kleines Unterfangen, beläuft sich doch die Zahl der zurzeit in der SWD befindlichen Datensätze mit dem Indikator s auf über 154.000.
Ein weiteres Fundament sind die Vorarbeiten aus dem gemeinsam von DNB, der Schweizerischen Landesbibliothek und anderen Partnern betriebenen Projekt Multilingual Access to Subjects (MACS). Im Rahmen von MACS wurden in größerem Umfang LCSH und Rameau-Datensätze miteinander verknüpft; einigen der dabei entstandenen Schlagwortpärchen wurde dabei bereits ein SWD-Äquivalent zugeordnet. Dreierverbindungen dieses Typs, erweitert um DDC-Notationen, werden auch im Rahmen von CrissCross entstehen. Die unterschiedliche Strukturierung der einzelnen Schlagwortsprachen sorgt allerdings für eine Vielzahl von Problemen, die das Projektteam bewältigen muss. Durch die Verlinkung der Schlagwortsprachen und die Verknüpfung mit der DDC erstellt CrissCross ein multilinguales verbales Recherchevokabular. Ungewöhnlich und innovativ ist dabei vor allem die Verbindung von verbaler und klassifikatorischer Sacherschließung, die zu einer bedeutenden Erweiterung der Recherchemöglichkeiten führen wird. Dies wird vor allem dann der Fall sein, wenn in Onlineumgebungen nutzbare Hilfsmittel wie das von der DNB zurzeit entwickelte Normdatenrecherchetool zur Verfügung stehen. In naher Zukunft wird der Nutzer dann bei seiner Suche auf eine Vielzahl unterschiedlich erschlossener Werke stoßen, ohne dass ihm die im Hintergrund vollzogene Auswertung von Normdaten bewusst sein muss. Er braucht im Grunde genommen überhaupt kein Vorwissen über Sacherschließungsinstrumente mitzubringen. »Simplify your search«, könnte das Motto dieser Vorgehensweise lauten. Die Nutzerfreundlichkeit der Bibliotheken wird durch den Einsatz derartiger Instrumente eine deutliche Steigerung erfahren. CrissCross wird seinen Teil dazu beitragen."

Abstract

The development of LC music headings is traced by reviewing the contributions and practices of the LC Music Division, the NYPL Music Division, and individual members of the Music Library Association. Cooperative efforts between LC and the Music Library Association are a hallmark of this development. Prospects for continuing and expanding this partnership continue today in the foundation provided by the Music Thesaurus Project

Abstract

The preparation of a bilingual Slovene-English general controlled vocabulary to be used for subject indexing in the COBISS.SI library information system, Slovenia, is a national project that started in March 2000. According to the basic methodology, a new subject schema named Splogni geslovnik COBISS.SI (COBISS.SI General List of Subject Headings) (SGC) is to be developed from the Sears List of Subject Headings (Sears). The project is divided into four phases: 1) translation and editing of Sears, 2) restructuring and adaptation of Sears and mapping of SGC headings to LCSH, 3) addition of new terms and preparation of instructions for use, and 4) conversion from the OCLC MARC format for authorities and inclusion of SGC in subject authority control system. By the end of 2002, the first part of Phase I was completed. Also described at some length are both the faceting of Sears headings and the addition of new terms based, among other, on LCSH.

Abstract

The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.

Abstract

LCSH are increasingly seen as 'the' English language controlled vocabulary, despite their lack of a theoretical foundation, and their evident US bias. In mapping exercises between national subject heading lists, and in exercises in digital resource organization and management, LCSH are often chosen because of the lack of any other widely accepted English language standard for subject cataloguing. It is therefore important that the basic nature of LCSH, their advantages, and their limitations, are well understood both by LIS practitioners and those in the wider information community. Information professionals who attended library school before 1995 - and many more recent library school graduates - are unlikely to have had a formal introduction to LCSH. Paraprofessionals who undertake cataloguing are similarly unlikely to have enjoyed an induction to the broad principles of LCSH. There is currently no compact guide to LCSH written from a UK viewpoint, and this eminently practical text fills that gap. It features topics including: background and history of LCSH; subject heading lists; structure and display in LCSH; form of entry; application of LCSH; document analysis; main headings; topical, geographical and free-floating sub-divisions; building compound headings; name headings; headings for literature, art, music, history and law; and, LCSH in the online environment. There is a strong emphasis throughout on worked examples and practical exercises in the application of the scheme, and a full glossary of terms is supplied. No prior knowledge or experience of subject cataloguing is assumed. This is an indispensable guide to LCSH for practitioners and students alike from a well-known and popular author.

Abstract

Purpose - This paper aims at providing a robust, user-friendly and efficient navigation procedure in an online library catalog that is based on semantic information encapsulated within subject headings. Design/methodology/approach - The paper describes an interactive navigation procedure inside an online library catalog based on semantic information. The proposed approach is presented through a web-based, prototype application following the most recent trends of the semantic web such as AJAX technology and the web ontology language - OWL for encoding semantics. Findings - According to the proposed method, a GUI interface exposes the hierarchy of the subject headings employed within an OPAC, as well as all stated relations between such headings, as links that the user can follow, effectively traversing the ontology and formulating at the same time the actual query to the underlying OPAC. This act of interactive navigation through the library's assets aids searchers in accurately formulating their queries, by offering broader or narrower concepts for selection or indicating alternative or related concepts they might be initially unaware of. The augmented exposition of inter-relations between concepts provides multiple paths for information retrieval and enables searchers to fulfill their information needs in a faster, more efficient and intuitive manner. Practical implications - The paper includes implications for the development of modern, semantic web applications focused on the library domain. The novel approach of visualizing subject headings could be further extended to visualize a number of other conceptualizations of the library domain. Originality/value - This paper fulfils an identified need to take advantage of the "hidden knowledge" existing within the library domain but, for a number of reasons, is never exposed to the library users.

Rez. in: KO 36(2009) nos.2/3, S.180-181 (N.K. Swain): " ... The User's Guide will undoubtedly be of great help to practitioners and tutors, as each chapter includes a summary and exercises. The purpose suggested by the title is fulfilled, serving as a companion to the 19th edition of the Sears List. It is designed a a manual for beginners who will realize the importance of vocabulary control and subject analysis, and start to comprehend the structure and organization of the Sears List as well as the methods and techniques to locate, specify, and construct subject headings. The book, however, lacks a good number of examples for practice. The emphasis seems to have been put more on the theoretical than the practical aspects. Despite this criticism, I unreservedly value the authors' efforts. At the same time, I can't help but wonder if the book will have wide access as the place of publication, the cost and the availability will especially affect the users in developing countries. The User's Guide will be a valuable tool to technical services librarians, subject catalogers, students and teachers of library and information science. It is intended for college and university libraries in general, but more particularly for library schools. The authors produced a work of high quality that stands out in its category.
