Rez. in: JASIST 56(2005) no.11, S.1237-1238 (E. Yakel): "This book provides the profession with a cogent, thorough, and thoughtful introduction to digital reference. Janes not only provides the breadth of coverage expected in an introduction, but also depth into this important topic. Janes' approach is managerial or administrative, providing guidelines for reference work that can be applied in different settings. Janes creates a decision-making framework to help reference librarians make decisions concerning how, to what extent, and in what cases digital reference services will be delivered. In this way, Janes avoids dictating a "one-size-fits-all" model. This approach is the major strength of the book. Library administrators and heads of reference services will find the administrative approach welcome by helping them think through which digital reference policies and methods will best target core constituencies and their institutional environments. However, the book deserves a broader audience as professors will find that the book fits nicely in a general reference course. For all readers, the book is readable and engaging and also challenging and questioning. The book begins with a history of reference work, nicely positioning digital reference in this tradition and noting the changes wrought by the digital age. By doing this, the author establishes both continuity and change in reference work as well as the values surrounding this activity. These values are largely those from the library community and Support people's access to information as well as activities that support the use of information. Janes closes this chapter by noting that the continuing changes in demographics, technology, and connectivity will impact reference work in ways that are not yet imaginable. This introduction sets the tone for the rest of the book. Janes defines digital reference service as "the use of digital technologies and resources to provide direct, professional assistance to people who are seeking information, wherever and whenever they need it" (p. 29). This definition covers a lot of ground. Examples include everything from a public library answering email queries to commercial ask-an-expert services. While the primary audience is librarians, Janes continually reminds readers that many others perform reference activities an the World Wide Web. Furthermore, he cautions readers that there are larger forces shaping this activity in the world that need to acknowledged. In building a framework for decision-making, Janes outlines the types of digital reference service. This discussion covers the communieations modes, such as e-mail, chat, Web forms, etc. It also analyzes the modalities by which reference service is delivered: synchronous/ asynchronous. Using these two dimensions (communication method and synchronous/asynchronous), Janes presents the variety of contexts in which digital reference can take place and then outlines the strengths and weaknesses of each of these. This translates into a decision-making framework by which readers analyze their particular setting and then select the modes and modalities that world be most effective. This is a powerful device and demonstrates the many options (and perhaps also the obstacles) for providing digital reference service.
The discussion of modes for digital reference world be incomplete without focusing an the technologies that support this activity. E-mail, Web forms, chat, instant messaging, and videoconferencing, as well as the call center based software, are now being adapted for use in libraries. The book discusses the technologies currently available and an the horizon to support digital reference services. While these sections of the book may not age well, they will provide us with a historical glimpse of the nascent development of such tools and how they were used at the beginning of the digital reference age. True to the emphasis an decision-making, the chapter an technology includes a list of functions that reference librarians world want in software to support digital reference. While no current applications have all of these features, this list provides librarians with some ideas concerning possible features that can be prioritized to aid in a selection process. Despite the emphasis an technology, Janes contextualizes this discussion with several significant issues relating to its implementation. These include everything from infrastructure, collaborative service standards, service design, user authentication, and user expectations. The sections an collaborative service models and service design are particularly interesting since they are both in their infancy. Readers wanting an answer or the "best" design of either institutional or collaborative digital reference service will be disappointed. However, raising these considerations is important and Janes points out how crucial these issues will be as online reference service matures. User authentication in the context of reference service is especially tricky since tensions can emerge between license agreements and the range of people who may or may not be covered by these contracts querying reference librarians. Finally, no discussion of digital reference is complete without a discussion of the possibility of 24/7 reference service and the ensuing user expectations. While Janes has no answers to the dilemmas these raise, he does alert libraries providing digital reference services to some of the realities. One is that libraries will get a broader range of questions, which could impact staff time, collection development to support these questions, and necessitate either a confirmation of priorities or a reprioritization of activities. Another reality is that the users of digital reference services may never have partaken of their services before. In fact, for libraries funded to serve a particular constituency (public libraries, academic libraries) this influx of users raises questions about levels of service, funding, and policy. Finally, in keeping with the underlying theme of values that pervades the book, Janes points out the deeper issues related to technology such as increasing ability to track users an the web. While he realizes that anonymous information about those who ask reference questions world provide reference librarians with a great deal of information to hone services and better serve constituencies, he is well aware of the dangers involved in collectiog patron information in electronic form.
Given that the Web is constantly changing, Janes turns bis focus to the future of digital reference. Topics include changes in reference practice, restructuring resource utilization, and the evolving reference interview. These are crucial dimensions of digital reference practice that require attention. The most intriguing of these is the changing nature of the interaction with the patron. The majority of digital reference takes place without physical, aural, or visual eines to gauge understanding or to sense conclusion of the interaction. While Janes provides some guidelines for both digital reference interviewing and Web forms, he honestly admits that reference interviewing in the technologically mediated environment requires additional study in both the asynchronous and particularly synchronous communication modalities. As previously noted, Janes is as concerned about developing the infrastructure for digital reference, as he is about the service itself. By infrastructure, Janes means not only the technological infrastructure, but also the people and the institution. In discussing the need for institutionalization of digital reference, he discusses (re)training reference staff, staffing models, and institutionalizing the service. The section an institutionalizing the service itself is particularly strong and presents a 10-step planning process for libraries to follow as they consider developing online services. The book ends with some final thoughts and exhortations to the readers. The author, as in the rest of the book, encourages experimentation, innovation, and risk taking. These are not characteristics that are automatically associated with librarians, but these qualities are not alien to readers either. The theme of planning and the value of connecting people with information pervade this chapter. In this closing, Janes subtly tells readers that his guidelines and proposals are just that-there is no magic bullet here. But he does argue that there has been good work done and some models that can be adopted, adapted, and improved (and then hopefully shared with others). In the end, Janes leaves readers with a feeling that there is a place for library reference service in the digital realm. Furthermore, he is convinced that the knowledge and skills of reference librarians are translatable into this arena. By focusing an the institutionalization of digital reference services, Janes is trying to get libraries to better position themselves in the virtual world, beside the commercial services and the plethora of Web-based information competing for the patrons' attention."

Abstract

The history of the Library of Congress Subject Headings is traced, from its beginnings with the implementation of a dictionary catalog at the Library of Congress in 1898 to the present day. The author describes the most significant changes which have occurred in LCSH policies and practices during the 100-year period. Events noted near the end of the century indicate an increased willingness on the part of' the Library of Congress to involve the larger library community in the creation or revision of subject headings and other decision-making regarding the LCSH system. Finally, the author provides a summary of the other contributions to this collection of essays, a collection which celebrates the "centennial" of the world's most popular library subject heading language

Abstract

Surveys conducted during the last four years under the auspices of the International Federation of Library Associations and Organizations (IFLA) reveal that the Library of Congress Subject Headings is heavily used in national libraries outside of the United States, particularly in English-speaking countries. Many other countries report using a translation or adaptation of LCSH as their principal subject heading language. Magda Heiner-Freiling presents an analysis of the IFLA data, which also includes information on the classification schemes used by the libraries and whether or not the libraries have produced a manual on the creation and application of subject headings. The paper concludes with an Appendix showing the complete data from the 88 national libraries that respond to the surveys

Abstract

Im Jahr 1898 begann die Library of Congress mit der Arbeit an einem Schlagwortkatalog - die Geburtsstunde der 'Library of Congress subject headings' (LCSH). Heute stellen die LCSH das zentrale Werkzeug zur verbalen inhaltlichen Erschließung in der gesamten angloamerikanischen Welt dar. Auch die Kritik an diesem Erschließungssystem hat eine lange Geschichte: Sie lässt sich bis in die Mitte des vergangenen Jahrhunderts zurückverfolgen und betraf im Lauf der Zeit recht unterschiedliche Aspekte. Neu an der Debatte der letzten Jahre ist, dass die Struktur der LCSH ganz grundsätzlich in Frage gestellt wird. Eine Projektgruppe der Bibliothek der University of California etwa urteilte 2005: "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." In einer für die Library of Congress erstellten Expertise mit dem Titel 'On the record' von 2008 heißt es: "LCSH suffers (...) from a structure that is cumbersome from both administrative and automation points of view". Es wird empfohlen, die LCSH in ein flexibleres Werkzeug zu verwandeln: "Transform LCSH into a tool that provides a more flexible means to create and modify subject authority data." Dies beinhaltet zum einen ein "de-coupling of subject strings", also eine 'Entkoppelung' der fest zusammengefügten (präkombinierten) Eintragungen, und zum anderen die Möglichkeit, das LCSH-Vokabular für "faceted browsing and discovery" nutzbar zu machen . Besonders drastische Worte wurden 2006 im sogenannten 'Calhoun Report' gefunden - einem Papier, das mit seinen radikalen Thesen in der amerikanischen Bibliothekswelt viel Aufsehen erregte: Man müsse die Library of Congress dazu bringen, die LCSH zu 'zerschlagen' ("urge LC to dismantle LCSH") - ja, sie gar zu 'eliminieren' ("eliminate LCSH").

Abstract

Spanish is one of the most widely spoken languages in the world and a review of the lists of subject headings in this language reveals numerous efforts over a period of time, usually involving some form of collaboration, but largely isolated from each other. Technological developments suggest that a greater degree of cooperation is now possible and would be beneficial to the international library community if other barriers can be surmounted. The lcsh-es.org project demonstrates this concept in a practical way and suggest a new model for international cooperation in authority control. The site may be accessed at http://lcsh-es.org.

Abstract

Beim DIMDI erhalten Sie ab sofort die aktuelle deutsche Übersetzung des Thesaurus Medical Subject Headings (MeSH) 2006 der National Library of Medicine (NLM). Auf Anfrage liefern wir die neue Version 11.0 (Stand 2006) als kostenpflichtige XML-Datei auf CD-ROM. Gegenüber 2005 enthält derThesaurus 933 neue Deskriptoren. Andere wurden nach der aktuellen Terminologie umbenannt, obsolete Benennungen entfielen ganz. Da jede Deskriptorklasse in Konzepte und Unterkonzepte mit zugehörigen Begriffen unterteilt ist, beträgt die tatsächliche Zahl neuer Bezeichnungen etwa das Fünffache. Der laufend weiterentwickelte Thesaurus umfasst jetzt 23.880 Hauptschlagwörter (Main Headings). Zum Vergleich: vor zehn Jahren gab die NLM erst 18.436 Deskriptoren an. Zuwachs verzeichnet vor allem die Kategorie Chemische Substanzen, Drogen und Arzneimittel mit 684 neuen Schlagwörtern. Zahlreiche neue Begriffe enthalten auch die Kategorien Organismen, Krankheiten, Biowissenschaften, Anatomie sowie Analytische, diagnostische und therapeutische Verfahren und Geräte. Neue Deskriptoren sind beispielsweise Kalziumaktivierte Kaliumkanäle mit großer Leitfähigkeit, Tritonia-Meeresschnecke, Mesangiumzellen oder Bariatrische Chirurgie. Das DIMDI übersetzt den MeSH in enger Anlehnung an die amerikanische Vorlage und ist offizieller Herausgeber der deutschen Version (inkl. Urheberrechte). Der Thesaurus ist Bestandteil des UMLS (Unified Medical Language System) der NLM. Übersetzungen liegen auch in Finnisch, Französisch, Italienisch, Portugiesisch, Russisch und Spanisch vor.

Abstract

Das CrissCross-Projekt verfolgt die Zielsetzung, ein erweitertes multilinguales und thesaurusbasiertes Registervokabular zur Dewey-Dezimalklassifikation (DDC Deutsch) zu erstellen, das als Recherchevokabulars zu heterogen erschlossenen Dokumenten verwendet werden kann und soll damit die Ausgangsbedingungen für die Gestaltung von OPAC-Retrievalumgebungen verbessern helfen. Im einzelnen soll jedes Sachschlagwort der Schlagwortnormdatei (SWD) eine DDC-Notation erhalten und es sollen die im Projekt MACS begonnen Arbeiten fortgesetzt werden, Links zwischen den Schlagwörtern der SWD, den Library of Congress Subject Headings (LCSH) und dem Répertoire d'autorité-matière encyclopédique et alphabétique unifé (Rameau) herzustellen. In diesem Beitrag wird der Vorschlag gemacht, die Zielsetzung des Projektes darin zu sehen, eine Kern-Ontologie mit universalen Relationen als Klassifikation zu benutzen und die beteiligten Normdateien als zugeordnete semantische Netze zu entwickeln, indem nicht-generische Relationen die Aufgabe der durch die Lokalisierung gestellten Anforderungen übernehmen. Generische Relationen im bekannten Thesaurussinn sind für derartige semantische Netze nicht mehr erforderlich, da sie sich aus den generischen Beziehungen der Kern-Ontologie vererben.

Abstract

Diese Einführung in die Grundlagen der Dokumentation und des Information Retrieval, d.h. des Wiederauffindens von Information zu thematisch-inhaltlichen Fragen, entstand auf der Basis langjähriger Lehrerfahrung. Die sowohl theoretisch fundierte als auch praxisorientierte Darstellung der Daten-, Literatur- und Faktendokumentation enthält neben zahlreichen Übungen einen Beispiel-Thesaurus, die Besprechung realer Ordnungs- und Retrievalsysteme sowie ca. 200 Prüfungsfragen mit Antworten. Das Buch ist von zentraler Bedeutung für die Ausbildung von Dokumentaren, Bibliothekaren und Archivaren. Das Thema gewinnt aber auch an Bedeutung für Wissenschaftler aller Fachrichtungen. Das Buch ist in seiner systematischen Darstellung und didaktischen Aufbereitung einzigartig. Durch sein ausführliches Sachwortregister eignet es sich auch als Nachschlagewerk. In der vorliegenden vierten Auflage werden insbesondere Entwicklungen im Bereich des Internets und der Informationssysteme berücksichtigt.

Abstract

In its overall function as the archive of all German-language publications, the German National Library also collects and catalogues German-language literary works. Belles-lettres as well as children's and youth literature form a considerable part of the library's collection. From 1913 until 1990, the titles were assigned subject headings, were filed in the library's card subject catalogue according to genres and languages and (within these categories) were further divided into formal aspects, themes and motifs. The subject indexing of belles-lettres and children's and youth literature is unique in its scope and depth.

Abstract

Many kinds of structure can be discerned in the headings and rules governing the Library of Congress Subject Headings. By addressing these structures at different levels, librarians can develop different approaches to the machine-assisted validation of subject headings, from the checking of individual words to the validation of complex forms of heading/subdivision compatibility. Using computer programs to assist with maintenance of subject headings is becoming increasingly necessary as technical services librarians strive to create consistent and useful patterns of subject collocation in library catalogs

Abstract

This paper focuses on meaning as the core concern and challenge of interoperability in a multilingual context. Korean subject headings, presently translated from English, crystallize issues attached to the semantics of translation in at least two languages (Korean, with written Chinese, and English). Presenting a model microcosm, which explains grammatical and semantic characteristics, and allows a search for equivalence of headings that have the closest approximation of semantic ranges, the study concludes the necessary conditions for linking multilingual subject headings and suggests an interoperable model for the transfer of meaning of headings across languages and cultures.

Abstract

This paper presents a study that assessed the feasibility of applying the approach of the Faceted Application of Subject Terminology (FAST), an initiative of the Online Computer Library Center (OCLC), to records in the Ulrich's Periodicals Directory.? The goal is to determine whether a simplified application of Library of Congress Subject Headings (LCSH), as illustrated by FAST, would benefit the Ulrich's system. This feasibility study found that although a few problems were encountered in the process, overall the FAST database was useful for converting Ulrich's subject headings into FAST headings.
