    Abstract
    Das in den letzten Jahren wiedererwachte Interesse an der klassifikatorischen Erschließung und Recherche hat sich allem Anschein nach noch nicht ausreichend bis zu den Herstellern integrierter Bibliothekssysteme herumgesprochen. Wie wäre es sonst zu erklären, dass im OPAC-Modul eines führenden Systems wie Aleph 500 so gut wie keine Features für klassifikationsbasierte Recherchen zu erblicken sind? Tatsächlich finden wir heute einen im Vergleich zum einstigen System Bibos kaum veränderten Zustand vor: Notationen eines oder mehrerer Klassifikationssysteme können in einer durch MAB dafür bestimmten Kategorie (700, nebst Indikatoren) katalogisiert und dann recherchiert bzw. angezeigt werden. Doch welcher Benutzer weiß schon, was diese Notationen im einzelnen bedeuten? Wer macht sich die Mühe, dies selbst herauszufinden, um dann danach zu recherchieren? Hier liegt im wesentlich dasselbe Problem vor, das schon dem systematischen Zettelkatalog anhaftete und ihn zu einem zwar mühevoll erstellten, aber wenig genutzten Rechercheinstrument machte, das nur dann (zwangsläufig) angenommen wurde, wenn ein verbaler Sachkatalog fehlte. Nun könnte eingewandt werden, dass im Vergleich zu früher unter Aleph 500 wenigstens das Aufblättern von Indizes möglich sei, sodass im OPAC ein Index für die vergebenen Notationen angeboten werden kann (bzw. mehrere solche Indizes bei Verwendung von mehr als nur einem Klassifikationssystem). Gewiss, doch was bringt dem Uneingeweihten das Aufblättern des Notationsindex - außer einer alphabetischen Liste von kryptischen Codes? Weiter könnte man einwenden, dass es im Aleph-500-OPAC die so genannten Suchdienste ("services") gibt, mithilfe derer von bestimmten Elementen einer Vollanzeige hypertextuell weiternavigiert werden kann. Richtig, doch damit kann man bloß wiederum den Index aufblättern oder alle anderen Werke anzeigen lassen, die dieselbe Notationen - also einen Code, dessen Bedeutung meist unbekannt ist - aufweisen. Wie populär mag dieses Feature beim Publikum wohl sein? Ein anderer Einwand wäre der Hinweis auf das inzwischen vom Hersteller angebotene Thesaurus-Modul, das vermutlich auch für Klassifikationssysteme eingesetzt werden könnte. Doch wie viele Bibliotheken unseres Verbundes waren bisher bereit, für dieses Modul, das man eigentlich als Bestandteil des Basissystems erwarten könnte, gesondert zu bezahlen? Schließlich mag man noch einwenden, dass es im Gegensatz zur Bibos-Zeit nun die Möglichkeit gibt, Systematiken und Klassifikationen als Normdateien zu implementieren und diese beim Retrieval für verbale Einstiege in die klassifikatorische Recherche oder zumindest für die Veranschaulichung der Klassenbenennungen in der Vollanzeige zu nutzen. Korrekt - dies ist möglich und wurde sogar einst für die MSC (Mathematics Subject Classification, auch bekannt als "AMS-Klassifikation") versucht. Dieses Projekt, das noch unter der Systemversion 11.5 begonnen wurde, geriet jedoch nach einiger Zeit ins Stocken und fand bedauerlicherweise nie seinen Weg in die folgende Version (14.2). Mag auch zu hoffen sein, dass es unter der neuen Version 16 wieder weitergeführt werden kann, so weist dieses Beispiel doch auf die grundsätzliche Problematik des Normdatei-Ansatzes (zusätzlicher Aufwand, Kontinuität) hin. Zudem lohnt sich die Implementierung einer eigenen Normdatei 4 wohl nur bei einem größeren bzw. komplexen Klassifikationssystem, wogegen man im Falle kleinerer Systematiken kaum daran denken würde.

    Abstract
    Describes a research project, at Middlesex Polytechnic, aimed at evaluating a front end thesaurus to navigate users through subject searches in on-line catalogues (OPACs). The British Library sponsored project involves the adaptation of the RIN file, used for thesaurual control of the British National Bibliography (BNB), to be used as a front end for a MARC data base with PRECIS subject indexing

    Abstract
    Suggest reasons why there is no operational OPAC station yet in Iceland. Obstacles include the lack of compatability among computer systems adopted by the major libraries, the differing classification schemes used by them and the lack of a controlled indexing vocabulary or thesaurus for subject analysis in the Icelandic language. The Rejkjavik Municipal Library and the National Hospital Library, both users of the DOBIS/LIBIS system, will be the first users of a potential network of OPACs.

    Abstract
    Provides a background to the size, organisation, and activities of the University of Twente and its library, the only campus university in the Netherlands. Describes the development and integration of descriptors and their conversion into a thesaurus. Discusses national developments in subject cataloguing; the OPAC of Twente University Library; the changing role of the OPAC and of classification systems; international OPAC developments and evaluation of the Twente OPAC

    Abstract
    Focuses on the user and human-computer interaction (HCI) aspects of the research based on the Okapi text retrieval system. Describes 3 experiments using different approaches to query expansion, highlighting the relationship between the functionality of a system and different interface designs. These experiments involve both automatic and interactive query expansion, and both character based and GUI (graphical user interface) environments. The effectiveness of the search interaction for query expansion depends on resolving opposing interface and functional aspects, e.g. automatic vs. interactive query expansion, explicit vs. implicit use of a thesaurus, and document vs. query space
