    Abstract
    Catalogue use studies in manual and online environments over the last 50 years have been succesful in identifying user behaviour and causes of user failure, but they have not led to substantial change in catalogue codes of practices. The online environment offers a myriad of new challenges

    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
    Reports on a dramatic shift from subject to periodical title searching at Colorado University Libraries. States possible reasons for the change, examines problems encountered by users with searching the periodical title index and suggests how this change in online catalogue searching may affect future catalogue design and bibliographic instruction

    Abstract
    Stanford University's Socrates II and University of California at Berkeley's Pathfinder are 2 USA World Wide Web based online publication access catalogues under development. They differ in their design language (how an interface functionally and visually communicates to the users). Evaluates each system's interface design and their ability to communicate functionality to users: analyzes design in terms of: colour, buttons, metaphors, layout, and basic and advanced search modes. Concludes that the design languages of both systems have the right directive and have the potential to evolve

    Abstract
    Der Artikel betrachtet anhand einer Studie zum Benutzerverhalten bei der Online-Katalogrecherche den gegenwärtigen Stellenwert und das zukünftige Potential der Web-OPACs. Dabei werden zunächst die Ergebnisse einer quantitativen Logfile-Analyse sowie qualitativer Benutzertests erörtert, bevor aktuelle Entwicklungen der Webtechnologie, die unter den Schlagworten Web 2.0 und Web 3.0 propagiert werden, im Zusammenhang mit der Online-Recherche und der Entwicklung neuartiger Suchverfahren kurz diskutiert werden.

    Abstract
    LIAS, the Pennsylvania State University's (Penn State) integrated interactive online system, provides for messaging by the user to inform library staff of errors found in bibliographic records. The message is sent by use of the OOPS command, and results in a printout which is used by processing staff for online catalog maintenance. This article describes LIAS, the use of the OOPS command, the processing of the resulting OOPS reports, an assessment of the effect of its use, and some speculation on the expansion of the LIAS message system for use in catalog maintenance.

    Abstract
    Viele Benutzer haben Probleme im Umgang mit OPACs - das dokumentieren zahlreiche Usability-Studien in ausreichendem Maße. Benutzer benötigen also Hilfe, genauer: sie benötigen ein Online-Hilfesystem, das ihnen beim "Discovery", "Locate" und "Request"' von Dokumenten im OPAC unabhängig von den Öffnungszeiten der Bibliothek situationsgerechte Online-Hilfen anbietet. Mit dem Ausdruck "Online-Hilfe" assoziieren viele nur einen Fragezeichen-Button oder Module wie die sprechende Büroklammer der Microsoft-Office-Applikationen. Doch Online-Hilfe umfasst viel mehr, von der Rechtschreibkorrektur in Suchfeldern bis hin zu Recommender-Systemen. Definieren lässt sich Online-Hilfe als ein computergestütztes Werkzeug im virtuellen Raum, das an kritischen Stellen den Nutzer bei der erfolgreichen Durchführung einer Aktion unterstützt und/oder kontextbezogene Informationen gibt. "Kritisch" für die erfolgreiche Nutzung eines Angebotes sind solche Stellen, "an denen bei den Nutzern ein jeweils spezifisches oder differenziertes Wissen vorausgesetzt wird"2. Eine einzelne Hilfe, etwa ein erklärender Text, kann dem Benutzer nicht auf allen Ebenen der Interaktion mit dem System helfen. Deshalb ist es notwendig, mehrere Online-Hilfen zu kombinieren; man spricht dann von einem Online-Hilfesystem. Online-Hilfe ist ein wichtiges Forschungsthema, doch ist es vor allem im Bibliotheksbereich nur mangelnd theoretisch fundiert. Eine präzise Unterscheidung und Klassifikation der verschiedenen Arten von Online-Hilfen ist dabei eine notwendige Grundlage für weiterführende Analysen. Der vorliegende Beitrag erläutert die einzelnen Arten von Online-Hilfen in OPACs anhand der von der Autorin entwickelten Klassifikation nach Funktionalitäten3. Es werden vier Arten von Online-Hilfen unterschieden: erklärende Hilfen, aufbereitende/visuelle Hilfen, sucheinschränkende Hilfen und sucherweiternde Hilfen. Während die ersten beiden am Suchergebnis nichts ändern, beeinflussen sowohl die einschränkenden als auch die erweiternden Hilfen das Suchergebnis. Abbildung 1 zeigt die Klassifikation mit ihrer weiteren Untergliederung. Die technische Komplexität der angeführten Online-Hilfen nimmt dabei - in grober Näherung - von oben nach unten zu.

    Abstract
    The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

    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
    Patron queries at a four-year comprehensive college's online public access catalog were examined via transaction logs from March 2007. Three representative days were isolated for a more detailed examination of search characteristics. The results show that library users employed an average of one to three terms in a search, did not use Boolean operators, and made use of limits one-tenth of the time. Failed queries remained problematic, as a full one-third of searches resulted in zero hits. Implications and recommendations for improvements in the online public access catalog are discussed.

    Abstract
    Rules regarding cataloguing, subject headings, the way information in bibliographic records is organised and the catalogue's interface, or the way the screen is set up, are barriers to the use of online catalogues by children Describes the background to and implementation of a project to create a child orientation catalogue with a graphical user interface, or one that relies on pictures instead of text, within Denver Public Library in Colorado. Now called the Kid's catalog and commercially available from the Colorado Alliance of Research Libraries Co., the catalogue's software acts as a front end to a library's regular catalogue

    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
    The growing interest in end user or direct patron access to on-line bibliographic databases is reviewed with references to online catalogues, databases, and CD-ROMs. The literature of end user searching is surveyed with notes on: user training, software search aids, end user services in libraries: characterisation of end user searches; the role of librarians; and CD-ROMs as end user media
