    Abstract
    Mit der Inbetriebnahme des Online-Benutzerkataloges im vergangenen Jahr konnte die UB Kaiserslautern ihr integriertes lokales Bibliotheksinformationssystem um einen wichtigen Baustein ergänzen. Wie auch durch die Installation eines CD-ROM Netzes zur Abfrage der lokal vorgehaltenen CD-ROM Datenbanken sowie die Durchführung von Rechercheseminaren zur Nutzung von Online-Literaturdatenbanken bei externen Hosts wird den Benutzern zunehmend der Zugriff auf rechnergestützte Bibliotheksdienste von Terminals und Arbeitsplatzrechnern in den Lesesälen der Bibliothek und von ihren Arbeitsplätzen aus ermöglicht

    Abstract
    Der Beitrag berichtet über die Erstellung eines hierarchischen Browse- und Abfrage-Interfaces für die lokale Systematik der Bibliothek der Sigmund Freud Privatstiftung (Wien), deren Online-Katalog an der Zentrale des Österreichischen Bibliothekenverbundes (OBVSG) unter Aleph 500 geführt wird. Da dieses System selbst keinerlei Features für die klassifikatorische Recherche vorsieht, wurden 25 HTLM-Seiten in den OPAC integriert, die eine hierarchische Navigation auf den drei Ebenen der Systematik ermöglichen. Mittels eines wöchentlich automatisch eingesetzten Perl-Programms wird dabei auch angezeigt, mit welchen Treffermengen in der jeweiligen Klasse bzw. den zugehörigen Unterklassen (in etwa) zu rechnen ist; diese Anzeige ist ausserdem mit der unmittelbaren Suche nach den betreffenden Titeln verlinkt. Da vonseiten der Bibliothek lediglich die Notationen katalogisiert werden, erfolgt bei der Titel-Vollanzeige mittels einer JavaScript-basierten Umnutzung der Aleph-Funktion "Suchdienste" ebenfalls ein Link auf das hierarchische Interface, um die Bedeutung der jeweiligen Notation im systematischen Kontext zu veranschaulichen.

    Abstract
    Im letzten Heft der VÖB-Mitteilungen wurde über die Erstellung eines hie-rarchischen Browse- und Abfrage-Interfaces für die lokale Systematik im Online-Katalog der Bibliothek der Sigmund Freud Privatstiftung, der im Rahmen eines Aleph-Sharing-Lokalsystems an der Verbundzentrale OBVSG betrieben wird, berichtet. Im Hinblick auf die Darstellung der den Titeldatensätzen jeweils zugeordneten Systematikgruppen in der Vollanzeige des OPACs galt damals noch (sinngemäß): Da vonseiten der Bibliothek lediglich die Notationen katalogisiert werden, wird bei der Titel-Vollanzeige mittels einer JavaScript-basierten Umnutzung der Aleph-Funktion "Suchdienste" ein Link auf das hierarchische Interface generiert, um die Bedeutung der jeweiligen Notation im systematischen Kontext zu veranschaulichen. Diese Lösung, die zwar durchaus besser als das kommentarlose Display einzelner "nackter" Notationen war, ist nunmehr obsolet geworden. Ein vor kurzem implementierter, einfacher Automatismus aus der "Werkstatt" der Verbundzentrale bewirkt die Einspielung der Klassennamen bereits im Katalogisierungsprozess und macht so die Anzeige dieser Benennungen im Katalog (OPAC bzw. Bearbeitungs-GUI) möglich.

    Abstract
    Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

    Abstract
    Isolierte Bibliothekssysteme genügen nicht mehr dem Informationsbedürfnis des modernen Wissenschaftsbetriebes. PC-gestützte Arbeitsplätze und zunehmende Vernetzung ermöglichen die Integration lokaler, regionaler und überregionaler Datenbestände. Genormte Protokolle auf der Grundlage des ISO/OSI-Basisreferenzmodells erlauben Kommunikation und Datenaustausch heterogener EDV-Systeme auch unter unterschiedlichen Betriebssystemen. Diese Konzepte wurden am Beispiel eines Katalogisierungs- und Recherchesystems realisiert. In einer vernetzten Umgebung kann dieses System nicht nur den lokalen Bestand nachweisen und verwalten, sondern erlaubt auch den Online-Zugriff auf Campus- und regionale Verbunddaten. Der vorliegende Aufsatz diskutiert die eingesetzten ISO/OSI-Normen, beschreibt die Funktionsweise und den Einsatz des Systems und gibt einen Ausblick auf weitere Projekte, die auf ihm aufbauen

    Abstract
    Das Exzellenzcluster Kognitive Interaktionstechnologie (CITEC) an der Universität Bielefeld beschäftigt sich seit 2013 mit der virtuellen Realität (VR). Ausgehend von konkreten Projektkooperationen (Publikations- und Forschungsdatenmanagement) mit der Universitätsbibliothek ist die Idee entstanden, mit der in 2016 neu angebotenen Konsumer-VR-Hardware die im Labor entwickelten Interaktionstechniken auf geeignete Szenarien im Bereich von bibliothekarischen Umgebungen anzuwenden. Als interessantes Anwendungsgebiet kristallisierte sich im gemeinsamen Diskurs die Literatursuche heraus: Als Suchsystem wurde die Bielefelder BASE-Datenbank (d.i. Bielefeld Academic Search Engine mit inzwischen mehr als 100 Mio. indexierten Dokumenten) ausgewählt. Diese Auswahl erfolgte vor dem Hintergrund, dass sich die von zahlreichen externen Institutionen bereits genutzte API-Schnittstelle als universell und robust erwiesen hat und umfangreiche Funktionen bereitstellt. Auf der Grundlage der umfangreichen theoretischen und praktischen Erfahrungen des CITEC mit VRTechniken wurde der Prototyp für eine virtuelle Suchumgebung realisiert, der ein Retrieval in einem Suchraum von Online-Dokumenten erlaubt. Die Nutzerinnen und Nutzer können die Suchanfrage explorativ zusammenstellen und dabei die Ergebnisse intuitiv verwalten. Unterstützt werden sie dabei durch Ergebnisanzeige, Sortierung, Optimierung des Suchergebnisses mittels Suchverfeinerung (Drilldown-basiert) oder Anfrageerweiterung und Wiederverwendung von abgelegten Ergebnissen. Gleichzeitig wird der Zugriff- und Lizenzstatus visualisiert und die Detailanzeige der Metadaten des Objektes integriert.

    Abstract
    Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

    Abstract
    WWW-OPACs bieten Bibliotheksnutzern die Möglichkeit, von zu Hause oder vom Arbeitsplatz aus über Internet in den Beständen zu recherchieren, unter Umständen sogar Bestellungen aufzugeben oder Verlängerungen vorzunehmen. Scheidet ein Zugang übder das Internet aber aus technischen oder finanziellen Gründen aus, bietet sich als Übergangslösung immer noch der Zugriff via Telefon an. - Am Beispiel der StB Chemnitz wird deutlich, daß dieses Konzept keienswegs überholt ist: Denn obwohl man auch in Chemnitz mittelfristig eine WWW-Lösung anstrebt, soll den Nutzern aufgrund der großen Akzeptanz auch zukünftig der OPAC-Zugriff über Telefon möglich sein. Darüber hinaus wurden in Chemnitz die OPAC-Module von Stadtbibliothek und Universitätsbibliothek gekoppelt, eine Recherche ist an den internen OPAC-Plätzen in beiden Richtungen mit demselben Funktionsumfang möglich

    Abstract
    Analyses the OPAC at the Australian Catholic University in New South Wales, Castle Hill Campus using an object oriented model following Rumbaugh's methodology, as described in 'Object oriented modelling and design, 1991'. The process of analysis, although difficult, is one of the most effective ways of determining each function of a system of this kind. The methodology is especially useful as the data structure, behavioural and functional aspects of the system are displayed in separate diagrams. This is an advantage for those analysing systems, who can display many factors without confusing different aspects involved in the analysis process

    Abstract
    This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end-users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

    Abstract
    Um den Zugriff auf das sehr umfangreiche und gleichzeitig komplexe Angebot an elektronisch verfügbaren Informationsressourcen zu erleichtern, hat die ETH Zürich ein Portal entwickelt, mit dessen Hilfe ein einfacher und gleichzeitig personalisierter Zugang zu diesen Informationsangeboten möglich ist. Das seit Mitte letzten Jahres zur Verfügung stehende Portal myETH@eth.ch bietet allen Mitgliedern der ETH Zürich die Möglichkeit, aus gegenwärtig 26 Informationspaketen eine nach persönlichen Interessen zusammengestellte Auswahl zu treffen. Für bibliothekarische Interessen im engeren Sinne sind 6 Pakete von Bedeutung, deren Inhalte wiederum den persönlichen Prioritäten angepasst werden können. Nach dem Login werden dann die selbst definierten Ansichten angezeigt, um auf diese Weise einen rascheren Zugriff auf die jeweils relevanten elektronischen Angebote zu erhalten. Die heute vorliegende Version des Portals basiert auf der ursprünglich als bibliothekarische Portalanwendung entwickelten Plattform MyLibrary@ETH.ch.

    Abstract
    For decades print pathfinders have complemented card catalogues and been useful reference tools. They are overlooked as components of online catalogues, even though they can extend the depth of the catalogue. To encourage librarians to consider integrating pathfinders into online catalogues discusses problems in OPAC searching, describes the value and styles of pathfinders, and illustrates how to include them in a NOTIS system

    Abstract
    At Limburg Provincial Central Library and Information Service in the Netherlands the online public catalogue has been replaced by a new system, Foundation. The OPAC network was an automated version of the card catalogue, whereas Foundation has been developed entirely from scratch. The system runs on Windows software and assists even inexperienced users to formulate suitable search strategies. The system accepts online catalogue records from other sources and has attracted considerable intersts from several areas, including the publishing industry

    Abstract
    By the mid 1980s online bibliographic systems retrieved excessively large sets. Conversely, with standard Boolean systems, searches retrieved commonly nothing or too few records. In Nov. 92, 32% of searches yielded nothing from a retrieval set averaging 98. Offers solutions to these problems using MELVYL as a case study. Examines how non topical data such as date, language and location of document can improve topical searches. Explains OASIS and front end phototyping. Discusses adaptive retrieval, strategic commands, expanded retrieval and developments of OASIS. Covers aggregation of filtered sets, related terms, automatic progressive truncation, the SUMMARIZE LIBRARIES command, filing and filtering and collection analysis
