    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
    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
    Provides information on the characteristics of 5 online catalogue systems in 5 academic libraries in the austin, Texas and North Texas, USA, and their use by Korean students at University of North Texas, USA, in order to assist system managers in the selection of online catalogues. Proposes recommendations when designing, adopting, or managing a new online catalogue system. Topics for further studies on the characteristics of online systems and their use are also suggested

    Abstract
    Explores the retrieval and user issues related to the impact of including table of contents notes as a searchable field in online catalogues. Includes a review of evaluation criteria, a summary of previously published studies, and a conceptual model which addresses some of the disadvantages of the searchable MARC field

    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
