    Abstract
    Presents the findings of the South Ayrshire Libraries OPen Learning and the Internet project, Sep 1997 to Oct 1998. The objective was to demonstrate how open learning materials available on the Internet could be integrated with the provision of local open learning resources to provide an enhanced learning environment in public libraries. The main areas of concentration within the project were information skills support to public library users and the provision of WWW based independent materials to learners. The organisation and retrieval of Web based resources for local use was a major issue throughout the project. Recommends the adoption of Dublin Core metadata standards, the connection of databases of resources with searchable wen pages, and the development of thesauri of terms used to index the Web based resources locally. Sstaff training, and the new skills which will need to be developed, were identified as issues. Cost was also identified as a related issue, extending to issues such as access to open learning material and the Internet

    Abstract
    Durch die Möglichkeiten der Einbindung von Bibliotheken in internationale Kommunikationsnetzwerke wie dem Internet zeichnen sich völlig neue Potentiale für die Vermittlung und Distribution von Wissen ab. Die globale Vernetzung verbindet die elektronischen Bestände aller angeschlossenen Bibliotheken, Datenbankanbieter oder sonstiger Informationsprodutzenten zu einer einzigen 'virtuellen Bibliothek' - der alte Traum von einer umfassenden Enzyklopädie des Weltwissens scheint damit in greifbare Nähe zu rücken. Neue Formen von Informationsprodukten entstehen und damit gleichzeitig der Bedarf nach veränderten Methoden und Regeln der Wissenserschließung, -aufbereitung und -verteilung. Die direkte Zugänglichmachung von Dokumenten in elektronischer Form verändert auf gravierende Weise die Gepflogenheiten unserer traditionellen 'Informationskultur'. Mit der Dematerialisierung des Wissens, d.h. mit der Unabhängigkeit des Rohstoffs 'Wissen' von festgelegten Formaten und Trägermedien stellt vielleicht auch das 'Gebäude' Bibliothek in seiner bisherigen physischen Präsenz bald einen Anachronismus dar.

    Abstract
    Die deutschen nationalbibliographische Datenbank Biblio-Data wird in Teil A mit ihren Grundlagen vorgestellt. Biblio-Data basiert auf dem Information-Retrieval-System STAIRS von IBM, das durch Zusatzprogramme der ZMD verbessert wurde. Das Hauptgewicht dieses Beitrags liegt auf der Erörterung des Biblio-Data-Konzepts, nach dem die Daten der Deutschen Bibliographie retrievalgerecht aufbereitet und eingegeben werden. Auf Eigenarten, Probleme und Mängel, die daraus entstehen, dass Biblio-Data auf nationalbibliographischen Daten aufbaut, wird ausführlich eingegangen. Zwei weitere Beiträge zeigen an einigen Beispielen die vielfältigen Suchmöglichkeiten mit Biblio-Data, um zu verdeutlichen, dass damit nicht nur viel schenellere, sondern auch bessere Recherchen ausgeführt werden können. Teil B weist nach, dass Biblio-Data weder die Innhaltsanalyse noch die Zuordnung von schlagwörtern automatisieren kann. Im derzeitigen Einsatzstadium fällt Biblio-Data die Aufgabe zu, die weiterhin knventionall-intellektuell auszuführende Sacherschließung durch retrospektive Recherchen, insbesonderr durch den wesentlich erleichterten Zugriff auf frühere Indexierungsergebnisse, zu unterstützen. Teil C schildert die praktische Arbeit mit Biblio-Data bei bibliographischen Ermittlungen und Literaturzusammenstellunen und kommt zu dem Ergebnis, dass effektive und bibliographische Arbeit aus der sinnvollen Kombination von Datenbank-Retrieval und konventioneller Suche bestehet.

    Abstract
    After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.

    Abstract
    The aim of the CATRIONA (Cataloguing and Retrieval of Information over Networks Applications) feasibility study was to investigate the technical, organizational and financial requirements for the development of applications software and procedures to enable the cataloguing, calssification and retrieval of documents and other resources over networks such as the Internet. The CATRIONA feasibility study demonstrated that the idea of a distributed catalogue of Internet resources integrated with standard Z39.50 library system OPAC interfaces is already a practical proposition at its most basic level. Proposes that the next step should be a distributed CATRIONA demonstrator project, based on the Scottish University and Research Libraries (SCURL) group of libraries cooperating to catalogue local electronic resources and selected areas of BUBL Subject Trees, but also sufficiently 'open' to encompass other sites, projects and approaches

    Abstract
    Describes the final phase of the work on the ELINOR (Electronic Library INformation Online Retrieval) project at De Montfort University, Leicester, which concluded in 1996. ELINOR was 2 phase project with 3 overall goals: to create a practical pilot system based on a commercial product (Excalibur EFS); to investigate the expansion of a small scale electronic library to a larger, distributed library system; and to develop a more efficient and effective means of accessing and sharing resources within a networked multi campus institution. ELINOR was successful in demonstrating that libraries may conveniently digitize and supply smal collections of high demand materials over a campus network in text anf TIFF format. Operational conditions have so far indicated that the barriers are not technological but involve copyright, use issues and sustainability

    Abstract
    Describes work of the BOPAC2 project, funded by the British Library Research and Inoovation Centre, from Sep 1996 to Jan 1997, to investigate the issues involved in managing large and complex retrievals involving Z39.50 searches, including searches of multiple databases. The system is a WWW front end that allows simultaneously access to a number of library OPACs via Z39.50. The system is designed to make access to large and complex retrieval simpler, similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. Describes the design, development and evaluation of the system with suggestions for future work

    Abstract
    Die Schlagwortnormdatei (SWD) ist mit einem Umfang von ca. 150.000 Sachschlagwörtern das umfangreichste terminologisch kontrollierte deutschsprachige Vokabular, das zur verbalen Inhaltserschließung von Dokumenten genutzt werden und somit prinzipiell auch als Kandidat für den Aufbau semantischer Navigationsstrukturen im Online-Retrieval angesehen werden kann. Die Strukturierung der Schlagwörter in der SWD folgt den Vorgaben zur Ausweisung begrifflicher Strukturen in einem Thesaurus. Durch Veränderungen des der Erstellung der SWD zu Grunde liegenden Regelwerkes RSWK hat sich im Verlauf der Zeit ein Nebeneinander von unterschiedlich dichten Beziehungsnetzen ergeben, ohne dass hierzu bislang Details erhoben und dokumentiert wären. In dieser Studie werden Aussagen über den Aufwand gemacht, der erforderlich wäre, die semantische Relationenstruktur der Schlagwortnormdatei (SWD) zu homogenisieren. Hierzu wird eine quantitative und qualitative Analyse am Beispiel mehrerer Themengebiete vorgenommen. Die Berücksichtigung mehrerer Gebiete soll es gestatten, möglichst repräsentative Aussagen für das gesamte Vokabular abzuleiten. Die Autorinnen und Autoren der Studien sind sich angesichts der zur Verfügung stehenden begrenzten Ressourcen bewusst, dass dieser Anspruch nur mit Einschränkungen eingelöst werden kann. Die für die Analyse der Relationenstruktur benutzten Kriterien orientieren sich an Grundsätzen zur Gestaltung strukturierten Vokabulars sowie insbesondere der Eignung der SWD, zum Aufbau bestandsunabhängiger semantischer Navigationssysteme im Online-Retrieval, für Zwecke des wörterbuchgestützten automatischen Indexierens.
