    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.

    Abstract
    Die digitale Bibliothek, in der alles mit allem verlinkt ist, und man mit wenigen Klicks zur gewünschten Information gelangt, ist nach wie vor ein Traum vieler Bibliothekare und Benutzer. In der Realität aber existieren heterogene Informationssysteme nebeneinander: Online-Datenbanken, Aggregatordatenbanken, A&I-Datenbanken, Plattformen für E-Journals, OPACs. Zwischen diesen verschiedenen Systemen muss der Nutzer nun hin- und herschalten, um die gewünschte Information zu erhalten. Dass eine Verlinkung der verschiedenen elektronischen Ressourcen der Bibliothek ein Desiderat ist, hat inzwischen auch die Industrie erkannt. Es sind bereits erste Systeme auf dem Markt, die eine Navigation in heterogenen Informationsquellen ermöglichen. Zu nennen ist hier in erster Linie ExLibris SFX. Auch EBSCO hat mit LinkSource eine auf openURL basierte Lösung vorgelegt, um alle verfügbaren Quellen in eine Suchanfrage einzubinden. Diese Systeme sind prinzipiell sehr vielversprechend und von der Bibliothek sehr komfortabel zu managen, bewegen sich aber derzeit in einem preislichen Rahmen, der von den wenigsten Bibliotheken noch zusätzlich zu den ohnehin schon hohen Kosten für elektronische Ressourcen aufgebracht werden kann. An der UB Osnabrück und SuUB Bremen wurden daher Überlegungen angestellt, wie man ohne diese kostenpflichtigen Zusatzdienste die verschiedenen elektronischen Angebote der Bibliothek besser miteinander verknüpfen könnte. Konkret lautete die Fragestellung so: "Wie komme ich nach einer Recherche in einer bibliografischen Online-Datenbank zum Volltext?" Die meisten OnlineDatenbanken sind immer noch rein bibliografische Datenbanken, die allerhöchstens ein Abstract anbieten (A&I-Datenbanken). Erscheint ein Rechercheergebnis dem Benutzer so interessant, dass er gern den Volltext des betreffenden Artikels oder des Buches einsehen möchte, so hat er dazu mehrere Möglichkeiten: Die einfachste Möglichkeit liegt darin, den Volltext in elektronischer Form aufzurufen. Besteht diese Möglichkeit nicht, so muss er im OPAC recherchieren, ob der gesuchte Titel zumindest in gedruckter Version in der Bibliothek vorhanden ist. Ist dies nicht der Fall, so hat er die Möglichkeit, den Titel per Fernleihe oder document delivery zu bestellen. Diese drei Schritte - Aufrufen des Volltextes, Recherche im OPAC, Fernleihbestellung - sollten für den Benutzer dadurch vereinfacht werden, dass ent sprechende Links in die Online-Datenbanken integriert werden. So kann das aufwändige "kopieren und einfügen"- Verfahren entfallen. Die Einrichtung dieser verschiedenen Links brachte administrative, technische und lizenzrechtliche Probleme mit sich. Online-Datenbanken werden von verschiedenen Anbietern auf den Markt gebracht: von international agierenden Firmen bis hin zu kleinen Körperschaften. Es musste bei jedem Anbieter geklärt werden, welche Verlinkungen technisch und lizenzrechtlich möglich sind. Links zum elektronischen Volltext sind für den Nutzer sicherlich die ideale Lösung, denn so kann er vom Büro oder CIP-Pool aus den Artikel lesen bzw. ausdrucken, ohne in die Bibliothek gehen und dort nach der Print-Ausgabe suchen zu müssen. Bei Volltextlinks muss man zwischen zwei Arten von Links unterscheiden: Institutionsunabhängige Links sind zentral für alle Abonnenten der Online-Datenbank eingerichtet und werden immer angezeigt, unabhängig davon, ob die Bibliothek einen lizenzierten Volltextzugriff auf die betreffende elektronische Ressource hat. Institutionsabhängige Links sind nur für die elektronischen Ressourcen eingerichtet, für die die Bibliothek einen lizenzierten Zugang besitzt.
    Im Falle von institutionsunabhängigen Links werden Volltextlinks angezeigt, die allerdings nur dann funktionieren, wenn die Bibliothek auch die entsprechenden Lizenzrechte besitzt. Beim Nutzer führen diese Links schnell zu Frustration, wenn der erhoffte Volltext nicht angezeigt wird, zumal es nicht ersichtlich ist, dass der Zugang zum elektronischen Volltext von der Institution nicht lizenziert worden ist. Dem Nutzer ist dann schwer zu vermitteln, dass diese Links immer auftauchten, es aber nicht immer möglich ist, auf den elektronischen Volltext zuzugreifen. Für die Bibliothek bedeuten institutionsunabhängige Links erhöhten Erklärungsbedarf: Die Nutzer müssen darüber informiert werden, bei welchen E-Journals sie an den Volltext gelangen können. Zusätzlich kompliziert wird diese Angelegenheit noch dadurch, dass Bibliotheken in aller Regel bei verschiedenen Verlagen verschiedene Zugriffsrechte haben: entweder auf gar keine Titel, oder auf die in Print abonnierten Titel oder (durch Konsortialverträge) einen cross access auch auf die Titel, die andere Bibliotheken abonniert haben. Zusätzlich sind auch noch zeitliche Beschränkungen zu bedenken: Elsevier beispielsweise gewährt für ScienceDirect Web-Editions nur Zugriff auf die Hefte der letzten 12 Monate.

    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
    Die seit ca. 1996 rasche Entwicklung des Internet bzw. des World Wide Web (WWW) hat die Praxis der Veröffentlichung, Verbreitung und Nutzung wissenschaftlicher Informationen grundlegend verändert. Um diese Informationen suchbar und retrievalfähig zu gestalten, ist in den letzten Jahren international viel diskutiert worden. Ein vielversprechender Ansatz, diesen neuen Herausforderungen zu begegnen, liegt in der Entwicklung von Metadatenprofilen. Da durch das Internet verschiedene Datenbestände, die von unterschiedlichen Bereichen wie Museen, Bibliotheken, Archiven etc. vorgehalten werden, unter einer Oberfläche durchsucht werden können, können Metadaten auch in diesem Bereich dazu beitragen, ein einheitliches Konzept zur Beschreibung und zum Retrieval von Online-Ressourcen zu entwickeln. Um die verteilt liegenden Dokumente unter einer Oberfläche für eine qualitativ hochwertige Recherche ("Cross-Search`) anbieten zu können, ist die Verständigung auf ein Core-Set an Metadaten und daran anschließend verschiedene Mappingprozesse ("Cross-walk`) von den lokalen Metadatenformaten zu dem Format des Core-Set an Metadaten notwendig. Ziel des Artikels' ist es, die einzelnen Schritte, die für die Entwicklung eines Metadatenprofils für die gemeinsame Suche über verteilte Metadatensammlungen notwendig sind, aufzuzeigen.

    Abstract
    Das Projekt "KOBV-Informationsportal" In den vergangenen Jahren hat der Kooperative Bibliotheksverbund BerlinBrandenburg (KOBV) mit der KOBV-Suchmaschine eine Internet-Plattform mit einer offenen Architektur geschaffen. Auf dieser technischen Basis erweitert er kontinuierlich sein Dienstleistungsangebot, wobei die Prinzipien des KOBV - insbesondere Offenheit, Heterogenität und Dezentralität auf technischer und organisatorischer Ebene - gewahrt bleiben. Mitte 2001 hat die KOBV-Zentrale gemeinsam mit den regionalen Bibliotheken das zweite große Entwicklungsprojekt "KOBV-Informationsportal" gestartet. Zielsetzung war der Aufbau eines kooperativen regionalen Portals mit Einsatz von Linking-Mechanismen zur "nahtlosen" Navigation in freien und lizenzierten Dokumenten und mit Einsatz von Instrumenten zur dezentralen Authentifizierung und Autorisierung über das Internet. Im Dezember 2003 hat das "KOBV-Portal - Digitale Bibliothek Berlin-Brandenburg" planmäßig in einer ersten Ausbaustufe den Routinebetrieb aufgenommen. Das KOBV-Portal bietet in dieser Stufe den Nachweis über die in den großen Bibliotheken lizenzierten Ressourcen und elektronischen Zeitschriften, zudem die nahtlose Navigation mittels des Reference-LinkingWerkzeuges SFX zu verschiedenen Diensten wie Fernleihe, Subito und freien Volltexten im Internet sowie zu frei zugänglichen elektronischen Zeitschriften. Die mit der verteilten Authentifizierung und Autorisierung verbundene Zielsetzung konnte im Rahmen des Projektes erst zum Teil umgesetzt werden. Realisiert wurde die Remote-Authentifizierung, mit der sich ein Nutzer, der online eine Fernleih-Bestellung aufgeben möchte, über das Internet in seiner Heimatbibliothek authentifizieren kann. Des weiteren ist der Zugriff auf lizenzierte Bestände im Campus einer Hochschule mittels IP-Checking möglich. Als weiteren wesentlichen Bestandteil des KOBV-Portals hat die KOBVZentrale mit den Bibliotheken einen Workflow für ein Metadata-Sharing abgestimmt und für die Adaption und Normalisierung lokaler Metadaten aus lokalen Bibliothekssystemen und -Portalen den KOBV-Metadaten-AustauschParser (KMA-Parser) entwickelt. Darüber hinaus sollen Bibliotheken, deren Metadaten bislang lediglich in unstrukturierter Form vorliegen, in die Lage versetzt werden, strukturierte Metadaten anzulegen, zu liefern und nachzunutzen. Dazu hat die KOBV-Zentrale das mit einer Web-Katalogisierungsschnittstelle ausgestattete "Metadata-Tool" entwickelt, das im Herbst 2004 in Betrieb genommen wird. Die für das Metadata-Sharing entwickelten Komponenten und Module sollen den Bibliotheken die Mehrfacherfassung ersparen und ihnen die Möglichkeit der wechselseitigen Nachnutzung der Metadaten eröffnen.

    "... 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.
    Neben die Pflege der Standards tritt als Herausforderung die Vernetzung der Systeme, um heterogene Dokumentenbestände zu verbinden. »Standardisierung muss von der verbleibenden Heterogenität her gedacht werden«." Diese Aufgaben können nur in Kooperation von Bibliotheken und Informationseinrichtungen gelöst werden. Die vorgestellten Projekte zeigen, wie dies gelingen kann. Sie verfolgen alle das Ziel, Informationen über Inhalte schneller und besser für die Nutzer zur Verfügung zu stellen. Fachliche Recherchen über mehrere Informationsanbieter werden durch die Heterogenität überwindende Suchdienste ermöglicht. Die Einführung der DDC im deutschen Sprachraum steht genau im Kern des Spannungsfeldes. Die DDC stellt durch ihren universalen Charakter nicht nur einen übergreifenden Standard her. Ihre Anwendung ist nur nutzbringend, wenn zugleich die Vernetzung mit den in Deutschland bewährten Klassifikationen und Thesauri erfolgt. Ziel des Projektes DDC Deutsch ist nicht nur eine Übersetzung ins Deutsche, die DDC soll auch in Form elektronischer Dienste zur Verfügung gestellt werden. Dr. Lars Svensson, Deutsche Bibliothek Frankfurt am Main, präsentierte anschaulichdie Möglichkeiten einer intelligenten Navigation über die DDC. Für die Dokumentenbestände Der Deutschen Bibliothek, des Gemeinsamen Bibliotheksverbundes (GBV) und der Niedersächsischen Staats- und Universitätsbibliothek Göttingen wurde prototypisch ein Webservice realisiert.
    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.
    Katja Heyke, Universitäts- und Stadtbibliothek Köln, und Manfred Faden, Bibliothek des HWWA-Instituts für Wirtschaftsforschung Hamburg, stellten ähnliche Entwicklungen für den Fachbereich Wirtschaftswissenschaften vor. Hier wird eine Crosskonkordanz zwischen dem Standard Thesaurus Wirtschaft (STW) und dem Bereich Wirtschaft der SWD aufgebaut." Diese Datenbank soll den Zugriff auf die mit STW und SWD erschlossenen Bestände ermöglichen. Sie wird dazu weitergegeben an die virtuelle Fachbibliothek EconBiz und an den Gemeinsamen Bibliotheksverbund. Die Crosskonkordanz Wirtschaft bietet aber auch die Chance zur kooperativen Sacherschließung, denn sie eröffnet die Möglichkeit der gegenseitigen Übernahme von Sacherschließungsdaten zwischen den Partnern Die Deutsche Bibliothek, Universitäts- und Stadtbibliothek Köln, HWWA und Bibliothek des Instituts für Weltwirtschaft Kiel. Am Beispiel der Wirtschaftswissenschaften zeigt sich der Gewinn solcher KonkordanzProjekte für Indexierer und Benutzer. Der Austausch über die Erschließungsregeln und die systematische Analyse der Normdaten führen zur Bereinigung von fachlichen Schwachstellen und Inkonsistenzen in den Systemen. Die Thesauri werden insgesamt verbessert und sogar angenähert. Die Vortragsreihe schloss mit einem Projekt, das die Heterogenität der Daten aus dem Blickwinkel der Mehrsprachigkeit betrachtet. Martin Kunz, Deutsche Bibliothek Frankfurt am Main, informierte über das Projekt MACS (Multilingual Access to Subject Headings). MACS bietet einen mehrsprachigen Zugriff auf Bibliothekskataloge. Dazu wurde eine Verbindung zwischen den Schlagwortnormdateien LCSH, RAMEAU und SWD erarbeitet. Äquivalente Vorzugsbezeichnungen der Normdateien werden intellektuell nachgewiesen und als Link abgelegt. Das Projekt beschränkte sich zunächst auf die Bereiche Sport und Theater und widmet sich in einer nächsten Stufe den am häufigsten verwendeten Schlagwörtern. MACS geht davon aus, dass ein Benutzer in der Sprache seiner Wahl (Deutsch, Englisch, Französisch) eine Schlagwortsuche startet, und ermöglicht ihm, seine Suche auf die affilierten Datenbanken im Ausland auszudehnen. Martin Kunz plädierte für einen Integrationsansatz, der auf dem gegenseitigen Respekt vor der Terminologie der kooperierenden Partner beruht. Er sprach sich dafür aus, in solchen Vorhaben den Begriff der Thesaurus föderation anzuwenden, der die Autonomie der Thesauri unterstreicht.

    Abstract
    The combination of different text representations and search strategies has become a standard technique for improving the effectiveness of information retrieval. Combination, for example, has been studied extensively in the TREC evaluations and is the basis of the "meta-search" engines used on the Web. This paper examines the development of this technique, including both experimental results and the retrieval models that have been proposed as formal frameworks for combination. We show that combining approaches for information retrieval can be modeled as combining the outputs of multiple classifiers based on one or more representations, and that this simple model can provide explanations for many of the experimental results. We also show that this view of combination is very similar to the inference net model, and that a new approach to retrieval based on language models supports combination and can be integrated with the inference net model

    Abstract
    User demands to have access to complete and actual information about research may require integration of data from different CRISs. CRISs are rarely homogenous systems and problems of CRISs integration must be addressed from technological point of view. Implementation of CRIS providing access to heterogeneous data distributed among a number of CRISs is described. A few technologies - distributed databases, web services, semantic web are used for distributed CRIS to address different user requirements. Distributed databases serve to implement very efficient integration of homogenous systems, web services - to provide open access to research information, semantic web - to solve problems of integration semantically and structurally heterogeneous data sources and provide intelligent data retrieval interfaces. The problems of data completeness in distributed systems are addressed and CRIS-adequate solution for data completeness is suggested.

    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
    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
    The HILT High Level Thesaurus Project aims to study and report an the problern of cross-searching and browsing by subject across a range of communities, services, and service or resource types in the UK given the wide range of subject schemes and associated practices in place in the communities in question (Libraries, Museums, Archives, and Internet Services) and taking the international context into consideration. The paper reports an progess to date, focusing particularly an the inter-community consensus reached at a recent Stakeholder Workshop.

    Abstract
    From 4 to 6 June 2003 the 2nd European Library Seminar / 3rd Gabriel Workshop was held at the Biblioteca Nacional in Lisbon, Portugal. 62 librarians and webmasters from 20 countries participated in the workshop, mainly Gabriel contacts but also quite a number of librarians from Portugal. Since its foundation in 1995 Gabriel, the world wide web service of the European national libraries, has established itself as the official network service of the Conference of European National Librarians (CENL) and has undergone a continuous development. The Gabriel website has been redesigned and restructured, and it was relaunched in summer 2002. At present, 41 libraries from 39 European countries are represented in Gabriel. Gabriel offers access to varied information sources and numerous online-catalogues and Services of the European national libraries. Gabriel is the only trans-European library service.

    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.
    Footnote
    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."

    Abstract
    Purpose - Biodiversity resources are inevitably digital and stored in a wide variety of formats by researchers or stakeholders. In Malaysia, although digitizing biodiversity data has long been stressed, the interoperability of the biodiversity data is still an issue that requires attention. This is because, when data are shared, the question of copyright occurs, creating a setback among researchers wanting to promote or share data through online presentations. To solve this, the aim is to present an approach to integrate data through wrapping of datasets stored in relational databases located on networked platforms. Design/methodology/approach - The approach uses tools such as XML, PHP, ASP and HTML to integrate distributed databases in heterogeneous formats. Five current database integration systems were reviewed and all of them have common attributes such as query-oriented, using a mediator-based approach and integrating a structured data model. These common attributes were also adopted in the proposed solution. Distributed Generic Information Retrieval (DiGIR) was used as a model in designing the proposed solution. Findings - A new database integration system was developed, which is user-friendly and simple with common attributes found in current integration systems.

    Abstract
    Integration der Navigation und Suche in lizenzierten Journalen und gleichzeitig in freien digitalen Dokumenten unter einer einheitlichen konsistenten Nutzeroberflache ist eines der ungelösten F&E-Probleme der Fachinformation. Hierbei müssen Elemente des Invisible Web und des Visible Web unter Berücksichtigung offener Standards nahtlos miteinander verbunden werden. Der Artikel beschreibt Ausgangspunkt und Entwicklungsgeschichte eines kooperativen Vorhabens "Verteilter Zeitschriftenserver", das sich auf dem Wege über eine Generalisierung zum "Verteilten Dokumentenserver" zur Basis der Kooperation von vascoda und AGVerbund mit dem Ziel der Realisierung einer Offenen Digitalen Bibliothek der Wissenschaften entwickelte.

    Abstract
    The State Library of Iowa, USA, received a Higher Education Act title II grant from the US Dept. of Education in 1994 to create a demonstration project of new library information technologies. Describes 2 interlinked components of the project: Web-based union catalogue development and statewide deployment of the ANSI/NISO Z39.50 standard for database search and retrieval. Z39.50 was chosen because of its ability to searching multiple remote databases in a single session and its common interface across a variety of implementations. Use of a distributed Z39.50 search makes the need for maintaining large union catalogues unnecessary

    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
