    Abstract
    Die Kombination von gleichzeitig mehreren oder vielen intellektuell konstruierten Thesauri und maschineller Indexierung der Texte führt zu einer umfassenderen und spezifischeren Beschreibung von Dokumenten als die intellektuelle Klassifizierung oder die Indexierung allein. Durch die Expansion der Suchfrage um Thesauruseinträge wird der recall deutlich erhöht. Zugleich kann die intellektuelle Klassifizierung in überschaubaren Domänen dazu genutzt werden, baumartig in Dokumentenkollektionen zu navigieren oder die Suche erst in Teilbereichen der Klassifikation zu beginnen, um die precision zu erhöhen. Der Einsatz von Thesauruskollektionen wird an den Beispielen dandelon.com, Landtagsinformationssystem Vorarlberg und der Landeshomepage vorarlberg.at dargestellt.

    Abstract
    In der vorliegenden Form können die RSWK nicht befriedigen. Die geforderte hochdifferenzierte Erschließung ist in einem OPAC wegen der vielfältigen Abfragemöglichkeiten gar nicht nötig, ja eine einheitliche Indexierung und effiziente Suche is aufgrund der komplexen Regeln sogar erschwert. Aufgaben und Probleme der verbalen Sacherschließung in OPACs werden in dieser Arbeit aufgezeigt und Ansätze zu einer Alternative diskutiert. Der traditionelle Indexkatalog hat als Ergänzung des modernen Information Retrieval nur eine Zukunft, wenn die Möglichkeiten der EDV und der Faktor Mensch bei der Regelwerkentwicklung besser berücksichtigt werden

    Abstract
    This article deals with the meaningful processing of information in relation to two systems of Information processing: pre-coordination and post-coordination. The different approaches are discussed, with emphasis an the need for a controlled vocabulary in information retrieval. Assigned indexing, which employs a controlled vocabulary, is described in detail. Types of indexing language can be divided into two broad groups - those using pre-coordinated terms and those depending an post-coordination. They represent two different basic approaches in processing and Information retrieval. The historical development of these two approaches is described, as well as the two tools that apply to these approaches: thesauri and subject headings.

    Abstract
    Es werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für eine Reform der RSWK im Hinblick auf die Erfordernisse der OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Im vergangenen Jahr wurden die Ergebnisse der Expertengruppe mit dem Schwerpunkt Formalerschließung vorgelegt, nun folgen die Aussagen zur Sacherschließung, welche die Expertengruppe - in veränderter personeller Zusammensetzung unter Leitung von Dr. Friedrich Geißelmann, Regensburg - erarbeitet hat. Die bibliothekarische Öffentlichkeit ist aufgefordert, sich dazu bis zum Jahresende zu äußern. Beide Berichte beziehen sich aufeinander und versuchen, den Zusammenhang zwischen Formal- und Sacherschließung herzustellen. Vom gegenwärtigen Stand der Sacherschließung in deutschen Bibliotheken ausgehend - wozu auch durch die Gruppe im Frühjahr 1993 eine Umfrage in wissenschaftlichen und Öffentlichen Bibliotheken gemacht worden ist, werden die Grundprobleme der Sacherschließung in Online-Katalogen dargestellt. Ein anschließendes Kapitel behandelt das Verhältnis von verbaler und klassifikatorischer Erschließung. Ein wichtiger Teil der Aussagen betrifft das Gebiet der verbalen Sacherschließung und damit das nationale Regelwerk: Es werden Vorschläge für ein Reform der RSWK im Hinblick auf die Erfordernisse des OPAC unterbreitet. Regelwerk und Normdatei (SWD) bilden dabei eine Einheit und werden zusammen betrachtet. Es geht um Kettenbildung und Permutationsregeln, Kompositumbildung oder Zerlegung von Begriffen, Pleonasmus, Funktion der SWD, Ansetzung von Schlagwörtern, die Einführung eines Zeit-Codes, Erschließung literarischer Formen und Gattungen, den verwendeten Zeichensatz, den Umgang mit Verweisungen

    Abstract
    After a fundamental examination of the phenomenon of time, this paper presents the history, authority, and structure of period subdivisions and chronological terms in the three subject heading languages LCSH (Library of Congress Subject Headings), RAMEAU (Répertoire d'Autorité Matière Encyclopédique et Alphabétique Unifié), and RSWK (Regeln für den Schlagwortkatalog). Their usefulness in online searching is demonstrated using the online catalogs of the Library of Congress, the Bibliothèque nationale de France, and the Deutsche Bibliothek and is compared to the search options in selected digital encyclopedias (Encyclopaedia Britannica, Encarta, Brockhaus-Enzyklopädie). The author develops a model for common time retrieval across all three online catalogs, outlines the conditions for that model (time period code, chronological code, and chronology authority file), and proposes a search interface.

    Abstract
    Most indexed databases now include their thesauri and/or coding in their bibliographic files, searchable at the databases' online connect rates. Assesses the searchability of these on the different hosts. Thesauri and classifications are also available as diskette or CD-ROM products. Describes a number of these, highlighting the diskette thesaurus from IFI/Plenum Data for its flexible databases, the CLAIMS Uniterm and Comprehensive indexes to US chemical patents

    Abstract
    The Library of Congress Subject Headings (LCSH) is a subject structure used to index large collections throughout the world. Browsing a collection through LCSH is difficult using current on-line tools in part because they are inadequately integrated with information collections. Users of these LCSH browsing tools are expected to find a promising LCSH string before using it to search for the information itself; many users do not have the patience for such a two-step process. This article proposes a method to fully integrate a specific collection in its subset of the LCSH hierarchy in order to facilitate LCSH browsing as well as information retrieval. Techniques are described to match LCSH strings assigned to the collection with an established string from the authority records, and build their specific LCSH hierarchy. The resulting subset of LCSH structure is described in terms of its size and broader/narrower term statistics, and implications for browsing and information retrieval are discussed. The results of this research have implications for institutions wishing to further capitalize on existing LCSH organization investments for the purpose of subject browsing and information retrieval.

    Abstract
    Library of Congress Subject Headings (LCSH), a system originally designed as a tool for subject access to the Library's own collection in the late nineteenth century, has become, in the course of the last century, the main subject retrieval tool in library catalogs throughout the United States and in many other countries. It is one of the largest non-specialized controlled vocabularies in the world. As LCSH enters a new century, it faces an information environment that has undergone vast changes from what had prevailed when LCSH began, or, indeed, from its state in the early days of the online age. In order to continue its mission and to be useful in spheres outside library catalogs as well, LCSH must adapt to the multifarious environment. One possible approach is to adopt a series of scalable and flexible syntax and application rules to meet the needs of different user communities
