    Abstract
    Die Überführung der konventionellen Zettelkataloge in weltweit frei zugängliche Online-Kataloge zählt zu den größten Errungenschaften der Bibliotheksautomatisierung. Seit den ersten Implementierungen in den siebziger Jahren des letzten Jahrhunderts wurden die Programmfunktionen der "elektronischen Zettelkästen" stetig ausgebaut. Heutige Kataloge bilden den Kern integrierter Bibliothekssysteme, die sowohl die innerbetrieblichen als auch die geschäftsübergreifenden Prozesse unterstützen - angefangen von der Erwerbung über die Katalogisierung bis hin zur Ausleihe von Medien. Die Entwicklung der Bibliothekssysteme orientierte sich lange Zeit ausschließlich an bibliothekarischen Anforderungen. Die Bedürfnisse der Nutzer fanden kaum Berücksichtigung oder wurden in einigen Bereichen gänzlich außer Acht gelassen. Es ist daher nicht verwunderlich, dass ein Großteil der heutigen Benutzer Internet-Suchmaschinen als Einstieg für ihre Literaturrecherche verwendet. Internet-Suchmaschinen haben in den letzten zehn Jahren den Prozess der Informationsrecherche revolutioniert. Bekanntestes Beispiel ist der Weltmarktführer Google, der in Deutschland knapp 90 Prozent der an Suchmaschinen gerichteten Anfragen beantwortet. Der große Erfolg von Google gründet sich im Wesentlichen auf vier Faktoren: leichte Bedienbarkeit, Schnelligkeit der Suche, Größe des Indexvolumens und relevanzbezogene Ranking-Algorithmen. Insbesondere die von Internet-Suchmaschinen standardmäßig vorgenommene Sortierung der Treffer nach Relevanz hat das Suchverhalten der Nutzer nachhaltig beeinflusst. So zeigen verschiedene Studien, dass die Benutzer in der Regel nur zwei bis drei Begriffe in das einzeilige Suchformular eingeben und sich dann anschließend auf die Treffer beschränken, die ohne Scrollen zu erreichen sind. Durchschnittlich werden daher pro Recherche lediglich fünf Treffer angeklickt und gesichtet. Der gesamte Vorgang dauert nur etwa 15 Sekunden. Wird das Gesuchte in dieser Zeit nicht gefunden, wird die Suche abgebrochen oder modifiziert. Das bei den Suchmaschinen zur Gewohnheit gewordene Suchverhalten wird von den Nutzern zunehmend auch auf andere Recherchesysteme übertragen. Bibliotheken und Softwarehersteller von Bibliothekssystemen haben diesen Trend erkannt und in den letzten Jahren verstärkt damit begonnen, ihre Suchsysteme an die geänderten Nutzungsgewohnheiten der Endanwender anzupassen.
