    Abstract
    Dieser Beitrag beschreibt eine Studie zur Entwicklung und Evaluierung von Rankingverfahren für bibliothekarische Informationssysteme. Dazu wurden mögliche Faktoren für das Relevanzranking ausgehend von den Verfahren in Websuchmaschinen identifiziert, auf den Bibliothekskontext übertragen und systematisch evaluiert. Mithilfe eines Testsystems, das auf dem ZBW-Informationsportal EconBiz und einer web-basierten Software zur Evaluierung von Suchsystemen aufsetzt, wurden verschiedene Relevanzfaktoren (z. B. Popularität in Verbindung mit Aktualität) getestet. Obwohl die getesteten Rankingverfahren auf einer theoretischen Ebene divers sind, konnten keine einheitlichen Verbesserungen gegenüber den Baseline-Rankings gemessen werden. Die Ergebnisse deuten darauf hin, dass eine Adaptierung des Rankings auf individuelle Nutzer bzw. Nutzungskontexte notwendig sein könnte, um eine höhere Performance zu erzielen.

    Abstract
    Die Vielzahl der Publikationen zeigt, dass Information Seeking Behaviour (ISB) bzw. Informationssuchverhalten in der informationswissenschaftlichen Forschung als relevantes Thema angesehen wird. ISB versteht sich als Unterkategorie von Information Behaviour (IB) bzw. Informationsverhalten, das jegliches menschliches Verhalten mit Bezug zu Wissen und Information umfasst, also z. B. auch Informationsvermeidung oder passives Informationsverhalten. ISB hingegen wurde anfänglich meist als bewusster Prozess verstanden, um sich aufgrund einer festgestellten Wissenslücke Information zu beschaffen. Information Seeking wird als eine alltägliche Aktivität angesehen, die meist dann auftritt, wenn eine informationell unterbestimmte Handlung durchgeführt werden soll
