    Abstract
    In der vorliegenden Arbeit werden die wichtigsten Informationen über Entwicklungen in Bezug auf die Benutzeroberfläche und die Recherchemöglichkeiten von OPACs und ihrem Umfeld zusammengetragen, gewichtet und bewertet. Heute schon realisierte Konzepte und viel verspre-chende Modelle für die Zukunft werden vorgestellt. Besondere Berücksichtigung finden die Interessen der Nutzer, und wie deren unterschiedlichen Ansprüchen und Voraussetzungen möglichst optimal Rechnung getragen werden kann.

    Content
    "Die Recherche im "klassischen" OPAC verlangt eine exakte Formulierung der Suchanfrage, aber viele Bibliotheksbenutzer wissen nicht genau, wonach sie eigentlich suchen. So bleiben oft wertvolle Treffer oder sogar Teile des Bibliotheksbestandes von den Bibliotheksbenutzern unentdeckt. Ein neues Produkt in der Angebotspalette des Bibliothekssoftware-Herstellers BOND GmbH & Co. KG schafft Abhilfe: Der AquaBrowser Library. Er sprengt die Grenzen der konventionellen OPAC-Suche und bietet ein neues, "ergonomisches" Sucherlebnis: die erste progressive und interaktive Suchumgebung. AquaBrowser Library bezieht in die OPAC-Suche automatisch assoziative Begriffe, Synonyme, unterschiedliche Schreibweisen, Übersetzungen sowie den Kontext mit ein. So werden automatisch neue Suchpfade generiert, der Suchbereich und somit auch das Trefferspektrum erweitert. Als Ergebnis erhält der Informationssuchende eine umfangreichere und qualitativ präzisere Ergebnisliste. Das Suchergebnis geht weit über eine Suchliste hinaus: Der Suchbegriff eines Benutzers wird mit den im Bibliothekskatalog enthaltenen Metadaten verglichen. Dabei werden assoziative Begriffe, Synonyme, alternative Schreibweisen, Übersetzungen in Fremdsprachen sowie der Kontext mit einbezogen. Daraus generiert sich automatisch eine visuelle Karte, die so genannte "Word Cloud". Sie stellt alle Assoziationen oder Überblicke über interessante Themenbereiche grafisch logisch dar. Die Begriffe sind Vorschläge und Hilfestellungen für den Bibliotheksbenutzer. Per Klick auf die "Word Cloud" kann er so neue Informationen entdecken und seine Suchanfrage präzisieren und lenken. Beispielsweise werden Tippfehler erkannt und alternative Schreibweisen angeboten. Gibt ein Leser den Suchbegriff "Auto" ein, beinhaltet das Suchergebnis auch Medien zu "PKW", "Kraftfahrzeug" oder "KFZ". Es werden sogar Treffer angezeigt, bei denen der gesuchte Begriff in einer anderen Sprache (englisch, spanisch oder niederländisch) im Katalogisat hinterlegt ist (z.B. car). Bei jeder Suchabfrage erstellt AquaBrowser Library automatisch eine Liste relevanter Kriterien, nach denen der Benutzer seine Ergebnisse filtern kann. Ein Klick auf ein Kriterium genügt und schon werden die Suchergebnisse präzisiert. Auf diese Weise schränken Mediensuchende die Treffer zielgenau ein und gelangen so schnell und exakt zu der spezifischen Information, die sie brauchen. Die Verfeinerungskriterien sind übersichtlich anhand von Kategorien gegliedert (z.B. Schlagwort, Verfasser, Sprache, Personen, Thema, Reihe oder Jahr)."

    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
    The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

    Abstract
    Reports and combines the results of 2 assessments of full bibliographic displays in the online catalogue of academic libraries. The first assessment evaluated displays in 12 OPACs while the second evaluated displays in 10 WWW based catalogues. Displays were evaluated against a checklist of desirable features derived from published display guidelines. Results showed that, on average, displays in OPACs scored 58% and displays in Web catalogues scored 60%. Discusses some of the weaknesses identified by the assessments, focusing on those found in the majority of the displays evaluated

    Abstract
    Over the last couple of years, there has been a surge of activity in the library automation arena directed toward improved user interfaces. As Breeding looks at the events and activities that have transpired over the last year or so, Breeding sees an incredible amount of progress in creating interfaces that help librarians compete better in an ever more crowded landscape of information providers. It's strategically important for libraries to have technologies in place that will optimize delivery of content and services in the context of today's Web. Breeding believes that failure to make progress in this area can foster a creep of irrelevancy as potential users increasingly rely on information resources provided by entities other than libraries.

    Abstract
    Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction

    Abstract
    Reports the results of a research project, conducted by the School of Computing and Mathematics and the Library of Huddersfield Polytechnic, into the problem of matching the user interface of OPACs to the needs of users. The project brought together issues involving: Human Computer Instruction (HCI); system methods in the determinination of user requirements; and user centred design, and prototyping in a sequence of design and evaluation cycles. These cycles applied appropriate HCI styles, techniques and equipment (such as Graphical User Interface (GUI) and a mouse pointing device) and incorporated the lessons of each evaluation, to produce an OPAC user interface, ICARUS, which differs considerably in style, behaviour and characteristcs from those commonly encountered in academic and public libraries. The project concluded by evaluating ICARUS, against the BLCMP OPAC with 38 subjects in the Library of Huddersfield Polytechnic, and demonstrating a significant improvement in performance for different tasks for the ICARUS interface

    Abstract
    Reviews the development of the British Library OPAC services leading up to the launch of OPAC 97, offering access to 9 mio bibliographic records and attempts to show the value of a user centred approach in the project management involved in developing such a service as recommended by Human Computer Interaction (HCI) studies. Reviews the evaluation studies of the Online Catalogue, the Network OPAC, a web prototype interface and of OPAC 97 and discusses the results in relation to the OPAC 97 project. Although the OPAC 97 interface made use of various HCI recommendations, user feedback sometimes contradicted these in specific instances, revealing the value of detailed user evaluation in developing services

    Abstract
    Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards

    Abstract
    Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system
