    Abstract
    Für fachspezifische bibliographische Online-Recherchen werden in den meisten Fällen die Ergebnisse nur der verbalen inhaltlichen Erschliessung genutzt (Deskriptoren, Schlagwörter, Stichwörter, Abstract-Texte). Viele bibliographische Datenbanken sind aber auch mit Hilfe von Notationen aus Klassifikationssystemen recherchierbar. Dieser Beitrag behandelt die letztere Form des sachlichen Zugriffs und streicht die Rolle von Notationen ("class codes") als nützliche Ergänzung zur verbalen Recherche heraus. Im ersten Teil werden folgende Fragen thematisiert: In welchem Ausmass sind Klassifikationsschemata als sachliche Zugriffsmöglichkeit in bibliographischen Datenbanken vorhanden? Welcher Art sind diese Schemata und ihre Notationen? Der zweite Teil veranschaulicht mehrere vorteilhafte Möglichkeiten der Anwendung von Notationen bei der bibliographischen Recherche. Der dritte Teil beschäftigt sich mit Änderungen von Klassifikationssystemen - dem Hauptproblem ihrer Verwendung bei der Online-Recherche. Der Rechercheur muss daher nicht nur wissen, wie Klassifikationen zur Verbesserung der Suchstrategie eingesetzt werden, sondern auch, wie Schwierigkeiten dieser Art zu bewältigen sind.

    Abstract
    Nach einer kurzen Einführung in die DK wird die Verwendung einer computerisierten fassung der DK in einigen Institutionen beschrieben, wie z.B. in der Bibliothek der ETH Zürich oder beim Österreichischen Arbeiterkammertag. Abfragemöglichkeiten über die DK werden am Beispiel von drei datenbanken aus drei verschiedenen Hosts diskutiert. Es sind: Economic Abstracts (Host: DIALOG), VWWW (Host: DATASTAR) und MATHDI (Host: INKA). Die besonderen Schwierigkeiten bei komplexen DK-Zahlen werden diskutiert und es wird vorgeschlagen, einen Algorithmus zum Aufbau von DK-Zahlen zu erstellen.

    Abstract
    Edited version of a report to the Australian Library and Information Association on the Conference on classification theory in the computer age, Albany, New York, 18-19 Nov 88, and on the meeting of the Dewey Editorial Policy Committee which preceded it. The focus of the Editorial Policy Committee Meeting lay in the following areas: browsing; potential for improved subject access; system design; potential conflict between shelf location and information retrieval; and users. At the Conference on classification theory in the computer age the following papers were presented: Applications of artificial intelligence to bibliographic classification, by Irene Travis; Automation and classification, By Elaine Svenonious; Subject classification and language processing for retrieval in large data bases, by Diana Scott; Implications for information processing, by Carol Mandel; and implications for information science education, by Richard Halsey.

    Abstract
    Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems

    Abstract
    Three pre-web articles about using hypertext for knowledge representation. Duncan discusses how to use graphical, hypertext displays (she used Xerox PARC's NoteCards on a Xerox 1186 workstation) along with concept maps and facet analysis, a combination that would now be done with topic maps. The screen shots of her graphical displays are quite interesting. Her interest in facets is in how to use them to show things to different people in different ways, for example, so that experts can enter knowledge into a system in one way while novices can see it in another. Duncan found that facet labels (e.g. Process and Product) prompted the expert to think of related concepts when inputting data, and made navigation easier for users. Facets can be joined together, e.g. "Agents (causing) Process," leading to a "reasoning system." She is especially interested in how to show relstionships between two things: e.g., A causes B, A uses B, A occurs in B. This is an important question in facet theory, but probably not worth worrying about in a small online classification where the relations are fixed and obvious. These articles may be difficult to find, in which case the reader can find a nice sumary in the next article, by Ellis and Vasconcelos (2000). Anyone interested in tracing the history of facets and hypertext will, however, want to see the originals.
