    Abstract
    Der vollständige Projektname von Renardus lautet "Academic Subject Gateway Service Europe". Renardus wird von der Europäischen Union im 5. Rahmenprogramm mit dem Schwerpunktthema "Information Society Technologies" im zweiten Thematischen Programm "Benutzerfreundliche Informationsgesellschaft" ('Promoting a User-friendly Information Society') gefördert. Die Projektlaufzeit ist von Januar 2000 bis Juni 2002. Insgesamt zwölf Partner (Principal und Assistant Contractors) aus Finnland, Dänemark, Schweden, Großbritannien, den Niederlanden, Frankreich und Deutschland beteiligen sich an diesem Projekt. Die Europäische Union unterstützt das Projekt mit 1,7 Mio. EURO, die Gesamtkosten belaufen sich inklusive der Eigenbeteiligungen der Partner auf 2,3 Mio. EURO. Das Ziel des Projektes Renardus ist es, über eine Schnittstelle Zugriff auf verteilte Sammlungen von "High Quality" Internet Ressourcen in Europa zu ermöglichen. Diese Schnittstelle wird über den Renardus Broker realisiert, der das "Cross-Searchen" und "Cross-Browsen" über verteilte "Quality-Controlled Subject Gateways" ermöglicht. Ein weiteres Ziel von Renardus ist es, Möglichkeiten von "metadata sharing" zu evaluieren und in kleinen Experimenten zwischen z. B. Subject Gateways und Nationalbibliothek zu testen bzw. zu realisieren

    Abstract
    Das von der Europäischen Union seit Januar 2000 geförderte Projekt Renardus hat das Ziel, einen Service zur Nutzung der in Europa vorhandenen "Quality-controlled Subject Gateways" aufzubauen, d.h. über einen Zugang bzw. eine Schnittstelle crosssearchen und crossbrowsen anzubieten. Für das crossbrowsen wird dabei zum Navigieren die Dewey Decimal Classification (DDC) verwendet. Der Beitrag beschreibt die einzelnen Entwicklungsschritte und stellt detailliert die nötigen Mappingprozesse vor. Dabei handelt es sich einmal um Mappingprozesse von den lokalen Metadatenformaten der einzelnen Subject Gateways zu dem gemeinsamen Kernset an Metadaten in Renardus für die Suche, wobei dieses Kernset auf dem Dublin Core Metadata Set basiert. Zum anderen geht es um die Erstellung von Konkordanzen zwischen den lokalen Klassen der Klassifikationssysteme der Partner und den DDC-Klassen für das Browsen. Der Beitrag beschreibt auch neue zugrunde liegende Definitionen bzw.theoretische Konzepte, die in der Metadatengemeinschaft zurzeit diskutiert werden (z.B. Application Profile, Namespace, Registry). Zum Schluss werden die Funktionalitäten des Renardus-Services (suchen, browsen) näher vorgestellt.

    Abstract
    Specifically designed for core units in library automation and information systems, this long awaited new text gives students a comprehensive overview of one of the most critical areas of library operations. Produced by two internationally known scholars, Thomas Kochtanek and Joseph Matthews, this book will enable students to take the lead in managing an immense diversity of information resources and at the same time handle the complexities that information technology brings to the library. Giving important insight into library information systems-from the historical background to the latest technological trends and developments-the book is organized into 14 chapters, each presenting helpful information on such topics as systems design, types of systems, coverage of standards and standards organizations, technology axioms, system selection and implementation, usability of systems, library information systems management, technology trends, digital libraries, and more. New to the acclaimed Library and Information Science Text Series, this book will prove an indispensable resource to students preparing for a career in today's ever-evolving library environment. Complete with charts and illustrations, chapter summaries, suggested print and electronic resources, a glossary of terms, and an index, this text will be of central importance to libraries and library schools everywhere.

    Rez. in: JASIST 54(2003) no.12, S.1166-1167 (Brenda Chawner): "Kochtanek and Matthews have written a welcome addition to the small set of introductory texts an applications of information technology to library and information Services. The book has fourteen chapters grouped into four sections: "The Broader Context," "The Technologies," "Management Issues," and "Future Considerations." Two chapters provide the broad content, with the first giving a historical overview of the development and adoption of "library information systems." Kochtanek and Matthews define this as "a wide array of solutions that previously might have been considered separate industries with distinctly different marketplaces" (p. 3), referring specifically to integrated library systems (ILS, and offen called library management systems in this part of the world), and online databases, plus the more recent developments of Web-based resources, digital libraries, ebooks, and ejournals. They characterize technology adoption patterns in libraries as ranging from "bleeding edge" to "leading edge" to "in the wedge" to "trailing edge"-this is a catchy restatement of adopter categories from Rogers' diffusion of innovation theory, where they are more conventionally known as "early adopters," "early majority," "late majority," and "laggards." This chapter concludes with a look at more general technology trends that have affected library applications, including developments in hardware (moving from mainframes to minicomputers to personal Computers), changes in software development (from in-house to packages), and developments in communications technology (from dedicated host Computers to more open networks to the current distributed environment found with the Internet). This is followed by a chapter describing the ILS and online database industries in some detail. "The Technologies" begins with a chapter an the structure and functionality of integrated library systems, which also includes a brief discussion of precision versus recall, managing access to internal documents, indexing and searching, and catalogue maintenance. This is followed by a chapter an open systems, which concludes with a useful list of questions to consider to determine an organization's readiness to adopt open source solutions. As one world expect, this section also includes a detailed chapter an telecommunications and networking, which includes types of networks, transmission media, network topologies, switching techniques (ranging from dial up and leased lines to ISDN/DSL, frame relay, and ATM). It concludes with a chapter an the role and importance of standards, which covers the need for standards and standards organizations, and gives examples of different types of standards, such as MARC, Dublin Core, Z39.50, and markup standards such as SGML, HTML, and XML. Unicode is also covered but only briefly. This section world be strengthened by a chapter an hardware concepts-the authors assume that their reader is already familiar with these, which may not be true in all cases (for example, the phrase "client-Server" is first used an page 11, but only given a brief definition in the glossary). Burke's Library Technology Companion: A Basic Guide for Library Staff (New York: Neal-Schuman, 2001) might be useful to fill this gap at an introductory level, and Saffady's Introduction to Automation for Librarians, 4th ed. (Chicago: American Library Association, 1999) world be better for those interested in more detail. The final two sections, however, are the book's real strength, with a strong focus an management issues, and this content distinguishes it from other books an this topic such as Ferguson and Hebels Computers for Librarians: an Introduction to Systems and Applications (Waggawagga, NSW: Centre for Information Studies, Charles Sturt University, 1998). ...
    Though the book definitely meets a need for an up-to-date introduction to library information systems and associated management issues, and the emphasis an management issues means that it will not date too quickly, there is room for improvement. Some topics are described too briefly to be useful, such as customization/personalization, which is covered in a single paragraph, and does not mention recent developments such as the MyLibrary concept. Other topics seem to have only a peripheral connection to the main chapter theme-for example, it is surprising to find a discussion of information literacy at the end of the chapter an system selection and implementation, and the material an personalization/customization is at the end of the discussion of intranets. Despite these comments, 1 would consider using this as a textbook in an introductory course an library automation or information technology, and practitioners who want to upgrade their knowledge of current practices and issues will also find it useful. People who are primarily interested in a specific topic, such as information systems planning or system selection and implementation are likely to find more specialized books such as Planning for Integrated Systems and Technologies: A How-to-Do-It Manual for Librarians by John M. Cohn, Anne L. Kelsey, and Keith Michael Fiels (New York: Neal-Schuman, 2001) more useful."

    Content
    "... unter diesem Motto hat die Deutsche Bücherei Leipzig am 23. März 2004 auf dem Leipziger Kongress für Bibliothek und Information eine Vortragsreihe initiiert. Vorgestellt wurden Projekte, die sich im Spannungsfeld von Standardisierung und Heterogenität der Sacherschließung bewegen. Die Benutzer unserer Bibliotheken und Informationseinrichtungen stehen heute einer Fülle von Informationen gegenüber, die sie aus zahlreichen Katalogen und Fachdatenbanken abfragen können. Diese Recherche kann schnell zeitraubend werden, wenn der Benutzer mit verschiedenen Suchbegriffen und -logiken arbeiten muss, um zur gewünschten Ressource zu gelangen. Ein Schlagwort A kann in jedem der durchsuchten Systeme eine andere Bedeutung annehmen. Homogenität erreicht man klassisch zunächst durch Normierung und Standardisierung. Für die zwei traditionellen Verfahren der inhaltlichen Erschließung - der klassifikatorischen und der verbalen - haben sich in Deutschland verschiedene Standards durchgesetzt. Klassifikatorische Erschließung wird mit ganz unterschiedlichen Systemen betrieben. Verbreitet sind etwa die Regensburger Verbundklassifikation (RVK) oder die Basisklassifikation (BK). Von Spezial- und Facheinrichtungen werden entsprechende Fachklassifikationen eingesetzt. Weltweit am häufigsten angewandt ist die Dewey Decimal Classification (DDC), die seit 2003 ins Deutsche übertragen wird. Im Bereich der verbalen Sacherschließung haben sich, vor allem bei den wissenschaftlichen Universalbibliotheken, die Regeln für den Schlagwortkatalog (RSWK) durchgesetzt, durch die zugleich die Schlagwortnormdatei (SWD) kooperativ aufgebaut wurde. Daneben erschließen wiederum viele Spezial- und Facheinrichtungen mit selbst entwickelten Fachthesauri.
    Dieses DDC-Tool ermöglicht den Zugriff auf lokale, mit DDC-erschlossene Titeldaten. Für einige bereits übersetzte DDC-Klassen kann mithilfe eines Browsers gearbeitet werden. Auch die gezielte verbale Suche nach DDC-Elementen ist möglich. Die Frage nach Aspekten, wie z. B. geografischen, soll durch getrennte Ablage der Notationselemente in den Titeldatensätzen ermöglicht werden. Schließlich lassen sich künftig auch integrierte Suchen über DDC und SWD oder andere Erschließungssysteme denken, um Literatur zu einem Thema zu finden. Das von Lars Svensson vorgestellte Retrieval-Interface bietet eine zentrale Lösung: nicht für jeden lokalen OPAC müssen eigene Suchstrukturen entwickelt werden, um auf DDC-Daten zugreifen zu können. Wie Datenbestände mit verschiedenen Erschließungen unter einer Oberfläche zusammengeführt werden und dabei die DDC als Meta-Ebene genutzt wird, das ist heute schon im Subject Gateway Renardus sichtbar." Der Renardus-Broker ermöglicht das Cross-Browsen und Cross-Searchen über verteilte Internetquellen in Europa. Für die Navigation über die DDC mussten zunächst Crosswalks zwischen den lokalen Klassifikationsklassen und der DDC erstellt werden. Das an der Universitätsbibliothek Regensburg entwickelte Tool CarmenX wurde dazu von der Niedersächsischen Staats- und Universitätsbibliothek Göttingen weiterentwickelt und ermöglicht den Zugriff auf die ver schiedenen Klassifikationssysteme. Über diese Entwicklungen berichtete Dr. Friedrich Geißelmann, Universitäsbibliothek Regensburg. Er leitete das CARMEN-Teilprojekt »Grosskonkordanzen zwischen Thesauri und Klassifikationen«, in dem das Werkzeug CarmenX entstand. In diesem CARMEN-Arbeitspaket erfolgten sowohl grundlegende methodische Untersuchungen zu Crosskonkordanzen als auch prototypische Umsetzungen in den Fachgebieten Mathematik, Physik und Sozialwissenschaften. Ziel war es, bei Recherchen in verteilten Datenbanken mit unterschiedlichen Klassifikationen und Thesauri von einem vertrauten System auszugehen und in weitere wechseln zu können, ohne genaue Kenntnis von den Systemen haben zu müssen. So wurden z. B. im Bereich Crosskonkordanzen zwischen Allgemein- und Fachklassifikationen die RVK und die Mathematical Subject Classification (MSC) und Physics and Astronomy Classification Scheme (PACS) ausgewählt.

    Abstract
    Describes the backgroud to the construction of a thesaurus at Hydro-Quebec, Quebec, Canada. Several information units, linked to form a network, share the same bibliographic database. The need for coherence and efficiency was the principle motive for the construction of the multidisciplinary thesaurus. Describes the construction process, discusses the specifity of the tool, its circulation, and considers its use on a partnership basis with other information services

    Abstract
    Z39.50 is an information retrieval protocol. It has generated much interest but is so far little deployed in UK systems and services. Gives a functional overview of the protocol itself and the standards background, describes some European initiatives which make use of it, and outlines various issues to do with its future use and acceptance. Z39.50 is a crucial building block of future distributed information systems but it needs to be considered alongside other protocols and services to provide useful applications

    Abstract
    Proposes a new model for bibliographic access, the virtual catalogue, to serve the virtual library. Suggests the use of current software and networks to build links between bibliographic databases of all kinds, including full text, to enable the user to search a specified subset of databases. Suggests that local data be limited to holdings information linked to, but separate from, bibliographic databases both local and remote

    Abstract
    The aims of CATRIONA were: (1) to investigate the requirements for developing procedures and applications for cataloguing and retrieval of networked resources, and (2) to explore the feasibility of a collaborative project to develop such applications and procedures and integrate them with existing library systems. The project established that a distributed catalogue of networked resources integrated with standard Z39.50 library system OPAC interfaces with information on hard-copy resources is already a practical proposition at a basic level. At least one Z39.50 OPAC client can search remote Z39.50 OPACs, retrieve USMARC records with URLs in 856$u, load a viewer like Netscape, and use it to retrieve and display the remotely held electronic resource on the local workstation. A follow-up project on related issues is being finalised.

    Abstract
    Federated search and distributed information retrieval systems provide a single user interface for searching multiple full-text search engines. They have been an active area of research for more than a decade, but in spite of their success as a research topic, they are still rare in operational environments. This article discusses a prototype federated search system developed for the U.S. government's FedStats Web portal, and the issues addressed in adapting research solutions to this operational environment. A series of experiments explore how well prior research results, parameter settings, and heuristics apply in the FedStats environment. The article concludes with a set of lessons learned from this technology transfer effort, including observations about search engine quality in the real world.

    Abstract
    Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

    Abstract
    The success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
    The papers discussing the transformation of traditional tools locate the point of transformation in different places. Some, like the papers an DDC, LCC and UDC, suggest that these schemes can be imported into the networked environment and used as a basis for improving access to networked resources, just as they improve access to physical resources. While many of these papers are intriguing, I suspect that convincing those outside the profession will be difficult. In particular, Edward O'Neill and his colleagues, while offering a fascinating suggestion for preserving the Library of Congress Subject Headings and their associated infrastructure by converting them into a faceted scheme, will have an uphill battle convincing the unconverted that LCSH has a place in the online networked environment. Two papers deserve mention for taking a different approach: both Francis Devadason and Maria Ines Cordeiro suggest that we import concepts and techniques rather than realized schemes. Devadason argues for the creation of a faceted pre-coordinate indexing scheme for Internet resources based an Deep Structure indexing, which originates in Bhattacharyya's Postulate-Based Permuted Subject Indexing and in Ranganathan's chain indexing techniques. Cordeiro takes up the vitally important role of authority control in Web environments, suggesting that the techniques of authority control be expanded to enhance user flexibility. By focusing her argument an the concepts rather than an the existing tools, and by making useful and important distinctions between library and non-library uses of authority control, Cordeiro suggests that librarianship's contribution to networked access has less to do with its tools and infrastructure, and more to do with concepts that need to be boldly reinvented. The excellence of this collection derives in part from the energy, insight and diversity of the papers. Credit also goes to the planning and forethought that went into the conference itself by OCLC, the IFLA Classification and Indexing Section, the IFLA Information Technology Section, and the Program Committee, headed by editor I.C. McIlwaine. This collection avoids many of the problems of conference proceedings, and instead offers the best of such proceedings: detail, diversity, and judicious mixtures of theory and practice. Some of the disadvantages that plague conference proceedings appear here. Busy scholars sometimes interpret the concept of "camera-ready copy" creatively, offering diagrams that could have used some streamlining, and label boxes that cut off the tops or bottoms of letters. The papers are necessarily short, and many of them raise issues that deserve more extensive treatment. The issue of subject access in networked environments is crying out for further synthesis at the conceptual and theoretical level. But no synthesis can afford to ignore the kind of energetic, imaginative and important work that the papers in these proceedings represent."
