    Abstract
    This article gives an overview of the design and organisation of DutchESS, a Dutch information subject gateway created as a national collaborative effort of the National Library and a number of academic libraries. The combined centralised and distributed model of DutchESS is discussed, as well as its selection policy, its metadata format, classification scheme and retrieval options. Also some options for future collaboration on an international level are explored

    Abstract
    Facettenklassifikationen wurden bislang vorwiegend im Hinblick auf ihre Verwendungsmöglichkeiten in präkombinierten systematischen Katalogen bzw. Bibliographien betrachtet, nicht so sehr unter dem Aspekt eines möglichen Einsatzes in postkoordinierenden Retrievalsystemen. Im vorliegenden Beitrag soll nachgewiesen werden, daß Facettenklassifikationen anderen Techniken des Online Retrievals überlegen sein können. Hierzu sollten Begriffs- und Facettenanalyse mit einem strukturabbildenden Notationssystem kombiniert werden, um mit Hilfe Boolescher Operatoren (zur Verknüpfung von Facetten unabhängig von einer definierten Citation order) und Truncierung hierarchisch differenzierte Dokumentenmengen für komplexe Fragestellungen zu erhalten. Die Methode wird an zwei Beispielen illustriert: das erste nutzt eine kleine, von B. Buchanan entwickelte Klassifikation, das zweite das für Library and Information Science Abstracts (LISA) verwendete Klassifikationssystem. Weiter wird am Beispiel PRECIS diskutiert, welche Möglichkeiten des syntaktischen Retrievals Rollenoperatoren bieten können.

    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
    Van Dijck builds up an example of actual XFML by showing how to organize tourist information about what restaurants in what cities feature which kind of music: <facet id="city">City</facet> and <topic id="ny" facetid="city"><name>New York</name></topic> combine to mean that New York is the name of a city internally represented as "ny". It is written in the usual clear and practical style of articles on xml.com. Highly recommended as an introduction for anyone interested in XFML.

    Abstract
    The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

    Abstract
    In order to enhance the use of Universal Decimal Classification (UDC) numbers in information retrieval, the authors have represented classification with multilingual thesaurus descriptors and implemented this solution in an automated way. The authors illustrate a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for subject authority records (i.e. the UDC-based multilingual thesaurus) and MARC XML support for data transfer. The multilingual thesaurus was built according to existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. This approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users

    Abstract
    Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual knowledge

    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    Abstract
    The Hierarchical Interface to Library of Congress Classification (HILCC) is a system developed by the Columbia University Library to leverage call number data from the MARC holdings records in Columbia's online catalog to create a structured, hierarchical menuing system that provides subject access to the library's electronic resources. In this paper, the authors describe a research initiative at the Cornell University Library to discover if the Columbia HILCC scheme can be used as developed or in modified form to create a virtual undergraduate print collection outside the context of the traditional online catalog. Their results indicate that, with certain adjustments, an HILCC model can indeed, be used to represent the holdings of a large research library's undergraduate collection of approximately 150,000 titles, but that such a model is not infinitely scalable and may require a new approach to browsing such a large information space.

    Abstract
    Networked orientated standards for vocabulary publishing and exchange and proposals for terminological services and terminology registries will improve sharing and use of all knowledge organization systems in the networked information environment. This means that documentary classifications may also become more applicable for use outside their original domain of application. The paper summarises some characteristics common to documentary classifications and explains some terminological, functional and implementation aspects. The original purpose behind each classification scheme determines the functions that the vocabulary is designed to facilitate. These functions influence the structure, semantics and syntax, scheme coverage and format in which classification data are published and made available. The author suggests that attention should be paid to the differences between documentary classifications as these may determine their suitability for a certain purpose and may impose different requirements with respect to their use online. As we speak, many classifications are being created for knowledge organization and it may be important to promote expertise from the bibliographic domain with respect to building and using classification systems.

    Abstract
    Describes the features und capabilities of the software SATSAN AUTOMATRIX version 1 for semi-automatic synthesis of Colon Class number (CCN) for a given subject according to the Postulational Approach formulated by S.R. Ranganathan. The present Auto-Matrix version l gives the user more facilities to carry out facet analysis of a subject (simple, compound. or complex) preparatory to synthesizing the corresponding CCN. The software also enables searching for and using previously constructed class numbers automatically, maintenance and use of databases of CC Index, facet formulae and CC schedules for subjects going with different Basic Subjects. The paper begins with a brief account of the authors' consultations with und directions received from. Prof A. Neelameghan in the course of developing the software. Oracle 8 and VB6 have been used in writing the programmes. But for operating SATSAN it is not necessary for users to he proficient in VB6 and Oracle 8 languages. Any computer literate with the basic knowledge of Microsoft Word will he able to use this application software.

    Abstract
    Die traditionellen Verfahren der klassifikatorischen sachlichen Erschließung von Medieninhalten heben auf die Eindeutigkeit der Zuordnung von Objekt (Medieninhalt) und Klasse ab. Sie unterscheiden sich damit in der Praxis des Online-Retrievals nur unwesentlich von den Verfahren der verbalen sachlichen Erschließung (z.B. Thesauri, SWD/RSWK). Auf der Grundlage der in der Sacherschließungstheorie vorgenommenen Unterscheidung von klassifikatorischer und verbaler Sacherschließung werden mögliche und bereits in Anwendung befindliche Verfahren diskutiert, welche die begrifflichen Kontexte der Klassen für den Anwender einer bibliothekarischen Klassifikation im Online-Retrieval nutzbar machen

    Abstract
    Dieser Beitrag referiert und dokumentiert die klassifikationsbasierten Anzeige- und Recherchemöglichkeiten, die 2005 anlässlich einer Versionsumstellung erstmals im OPAC des Österreichischen Bibliothekenverbundes implementiert wurden. Dazu wird einleitend ein kurzer Statusbericht über die im Titeldatenmaterial des Zentralkatologes vorhandenen Notationen gegeben. Danach werden die auf den Notationen der ZDB-Systematik, der Regensburger Verbundklassifikotion (RVK) und der Mathematics Subject Classification (MSC) aufbauenden OPAC-Features vorgestellt. Des weiteren wird ein bereits vorliegendes, aber noch nicht realisiertes Konzept zur Implementierung der MSC als Normdatei präsentiert, auf dem auch die künftige Verwendung der Basisklassifikation (BK) aufsetzen könnte.

    "Der Österreichische Verbundkatalog ist das zentrale Katalogisierungs- und Auskunftsinstrument des Österreichischen Bibliothekenverbundes, der grössten und bedeutendsten Kooperative wissenschaftlicher und administrativer Bibliotheken des Landes. Zur Zeit nehmen 62 Bibliotheken aktiv an diesem Verbund teil, darunter die Österreichische Nationalbibliothek und fast alle Universitätsbibliotheken. Mit dem Aufbau des elektronischen Verbundkataloges wurde 1988 begonnen; seit Anfang 1999 geschieht dies verbundweit unter Verwendung der Bibliotheksautomationssoftware "Aleph 500" der Firma ExLibris. Die Zahl der nachgewiesenen Titel beträgt mit Stand April 2005 über 4,3 Millionen (mit etwa 8,1 Millionen Exemplar- und 0,6 Millionen Zeitschriften-Bestandsnachweisen). Ursprünglich bezogen sich die Katalogisate schwerpunktmässig auf Publikationen seit etwa 1990, doch ist inzwischen aufgrund verschiedener Rückarbeitungsaktionen der Verbundteilnehmer auch ein beträchtlicher Anteil älterer Werke hinzugekommen. Überdies wurden in den 1990er Jahren die Zettel der "Büchernachweisstelle" (ein Zentralkatalog für den Zeitraum 1981-1993) retrokatalogisiert und Anfang 2000 die Daten der früheren "Österreichischen Zeitschriftendatenbank" (ÖZDB) in den Verbundkatalog eingearbeitet, wodurch nun auch eine grosse Zahl von Besitznachweisen von Bibliotheken ausserhalb des Verbundes vorhanden ist. Die verbale Sacherschliessung, an der sich der überwiegende Teil der Verbundbibliotheken beteiligt, erfolgt seit 1989 kooperativ nach RSWK und SWD. Nach einer aktuellen Statistik (April 2005) beträgt der Anteil der mit RSWK-Ketten versehenen Datensätze 44% - ein Wert, der den Vergleich mit deutschen Verbünden nicht zu scheuen braucht und in den letzten Jahren sogar ein wenig angestiegen ist. Was dagegen die klassifikatorische Sacherschliessung betrifft, so gab und gibt es in Österreich keine Einheitlichkeit; die in Deutschland in den 1970er Jahren verfolgte und schliesslich gescheiterte Idee einer "Einheitsklassifikation" war hierzulande kaum je ein Thema. Für die Zwecke der systematischen Erschliessung und/oder Buchaufstellung wurden und werden zahlreiche verschiedene Systematiken und Klassifikationssysteme verwendet, zum überwiegenden Teil "Haussystematiken" von unterschiedlicher Grösse und Komplexität. Internationale Universalklassifikationen wie etwa die UDC vermochten sich nicht durchzusetzen und werden nur vereinzelt angewandt. In jüngerer Vergangenheit hat sich allerdings das Interesse an der Regensburger Verbundklassifikation (RVK) verstärkt. Dieses System wurde etwa als präsumtives Ablösesystem für die veraltete Haussystematik der grossen germanistischen Fachbibliothek an der Universität Wien und als faktisches Aufstellungssystem für eine neu errichtete, geisteswissenschaftliche Fakultätsbibliothek in Innsbruck ausgewählt. Im Zuge des DFG-Projekts "DDC Deutsch" ist auch ein gewisses, vielleicht noch ein wenig abwartendes Interesse an der Dewey-Dezimalklassifikation entstanden.
    Die Vielfalt der eingesetzten Systematiken hat dazu geführt, dass klassifikationsbasierte Retrievalmöglichkeiten bisher, wenn überhaupt, nur in den lokalen Katalogen des Österreichischen Verbundes anzutreffen waren. Etwa ein Drittel der lokalen Bibliotheken bietet gegenwärtig in den betreffenden OPACs solche Suchoptionen in verschiedenen Ausformungen an. Im zentralen Verbundkatalog gab es bislang keine solchen klassifikationsbasierten Suchmöglichkeiten. Die lokalen Notationen werden ja beim Lokaldatensatz katalogisiert und gelangen nicht in den Verbundkatalog. Allerdings ist es auch bei der zentralen Katalogisierung der bibliographischen Daten möglich, die MAB-Kategorie 700 mit den verschiedenen Indikatoren für die Eingabe von Notationen bestimmter Klassifikationssysteme zu nutzen. Von dieser Möglichkeit wird sowohl aktiv als auch passiv (d.h. durch Fremddatenübernahme) Gebrauch gemacht.
