    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
    Despite early claims to the contemporary, thesauri continue to find use as access tools for information in the full-text environment. Their mode of use is changing, but this change actually represents an expansion rather than a contrdiction of their utility. Thesauri and similar vocabulary tools can complement full-text access by aiding users in focusing their searches, by supplementing the linguistic analysis of the text search engine, and even by serving as one of the tools used by the linguistic engine for its analysis. While human indexing contunues to be used for many databases, the trend is to increase the use of machine aids for this purpose. All machine-aided indexing (MAI) systems rely on thesauri as the basis for term selection. In the 21st century, the balance of effort between human and machine will change at both input and output, but thesauri will continue to play an important role for the foreseeable future

    Abstract
    "So haben wir inzwischen einen Stand der Diskussion erreicht, bei dem zwschen den Anforderungen an das, was Bibliotheken leisten sollten und dem, worüber Bibliothekare reden, eine immense Lücke klafft. Der Bericht der Expertengruppe Online-Kataloge ist dafür nur ein weiteres, leider trauriges Beispiel. Er ist aber auch - dies ist besonders zu bedauern - eine verpaßte Chance, denn hier hätte sich die ideale Gelegenheit geboten, für die neue Katalogform OPAC auch neue Möglichkeiten der Sacherschließung zu diskutieren. Da dies nicht geschehen ist, bleibt nur zu hoffen, daß unter dem sicher stärker werdenden Druck der Benutzer auf die Bibliotheken und deren Informationsangebot auch begonnen wird, offen über die bislang 'heilige Kuh' RSWK zu rden"

    Abstract
    Die Diskussion um Vor- und Nachteile von Präkoordination oder Postkoordination wird unter den in der verbalen Sacherschließung Engagierten in Deutschland seit Jahren geführt. Mit zunehmender Verbreitung der RSWK gewinnen die Überlegungen, die sich angesichts der Ausbreitung des OPAC für das 'Zerschlagen' der Schlagwortketten aussprechen, an Bedeutung. In diesem Zusammenhang trägt eine Berücksichtigung der internationalen Debatte um Prä- und Postkoordination zur Erweiterung des nationalen Horizontes bei. Der Beitrag ist eine leicht gekürzte Übersetzung eines Referates, das die Autorin beim IFLA Satellite Meeting zum Thema 'Subject indexing in the 90's - principles and practices' im August 1993 in Lissabon gehalten hat

    Abstract
    Vorsatz zum Sinn von Normdateien: "Die sachgerechte Nutzung von Normdateien erfordert eine ausgeklügelte Datenbankstruktur, über die sich Bibliothekare und Informatiker offensichtlich erst noch verständigen müssen"; Hauptsatz zur Redundanz von P,T,G,C,K,Z,F - verbale Sacherschließung als Funktion: "Außer den Sachschlagwörtern können alle anderen Schlagwortkategorien der RSWK/SWD 'eingespart', auf die Einrichtung eigener Schlagwortkettenfelder in den Titelaufnahmen kann verzichtet werden: Nachsatz zur 'Kombinatorik': "An die Stelle von Schlagwortketten würden Chiffren für Verknüpfungskombinationen ('Kombinationsmuster') treten, die auch im Sinne von Steuerungsinstrumenten zu nutzen wären"
