    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."

    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.

    "... 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.
