    Abstract
    Discovery Systeme erlauben einen neuen und anderen Zugriff auf verfügbare Ressourcen einer Bibliothek als die traditionellen Online-Kataloge. Daraus ergeben sich Probleme, aber auch Chancen für die Nutzung und Sichtbarkeit der bibliothekarischen Sacherschließung. Der Vortrag gibt einen Einblick in die Funktionalitäten und Funktionsweisen von Discovery Systemen am Beispiel eines großen Players, Primo von ExLibris, sowie die Auswirkungen auf bibliothekarische inhaltliche Metadaten. Es werden Chancen und Grenzen der Technik beleuchtet. Der Vortrag schließt mit der Reflektion der Implikationen für die Arbeit im Fachreferat.

    Abstract
    Die elektronischen Bibliotheksangebote konkurrieren zunehmend mit den allgemeinen Websuchmaschinen und spezialisierten Wissenschaftssuchmaschinen um die Gunst der Nutzer. Dieser Aufsatz gibt einen kritischen Überblick über die bisherigen Initiativen zum Einsatz von Suchmaschinentechnologie im Bibliothekskontext sowie zur Sichtbarmachung von Bibliotheksinhalten in allgemeinen Suchmaschinen. Darauf aufbauend wird dargestellt, wie Bibliotheksangebote tatsächlich für den Nutzer attraktiver werden können und ihre Sichtbarkeit in Suchmaschinen erhöht werden kann. Grundlegend muss der OPAC zum zentralen Nachweisinstrument für alle in der jeweiligen Bibliothek verfügbaren Informationen gemacht werden. Außerdem müssen die Katalogdaten deutlich angereichert werden, um die Stärken der Suchmaschinentechnologie auch tatsächlich nutzen zu können. Auf der Basis dieser erweiterten Textmenge kann schließlich auch leicht die Auffindbarkeit in allgemeinen Suchmaschinen verbessert werden.

    Abstract
    Mit der Einführung der neuen Suchmaschine Primo im Österreichischen Bibliothekenverbund wurde eine Neubewertung und Neuausrichtung der Anzeige, Indexierung und der erstmals möglichen Facettierung sacherschließender Elemente notwendig. Nach einem kurzen Überblick über die im Verbund zum Einsatz kommende Software sowie über Umfang und Art der inhaltlichen Erschließung im zentralen Katalog wird detailliert auf die angestrebte Umsetzung derselben in der neuen Suchmaschinenumgebung eingegangen, wobei der verbalen Erschließung durch RSWK-Ketten als wichtigste Form der intellektuellen Erschließung erhöhte Aufmerksamkeit zukommt. In einem zweiten Teil wird die konkrete technische Umsetzung in Primo beleuchtet, um abschließend einen Ausblick auf zukünftige Entwicklungen sowie projektierte Verbesserungen zu geben.

    Abstract
    Wissenschaftliche Bibliotheken werden heutzutage durch Universalsuchmaschinen wie Google bedroht. Ein Grund hierfür ist, dass Bibliotheken auf Rechercheinstrumente setzen die, die heutigen Erwartungen ihrer Nutzer nicht mehr erfüllen können. Wollen Bibliotheken auch zukünftig eine tragende Rolle spielen, müssen sie die Techniken in ihrer Produkte integrieren, die Suchmaschinen zu ihrem Erfolg im Web verholfen haben.

    Abstract
    One finding of the 2006 OCLC study of College Students' Perceptions of Libraries and Information Resources was that students expressed equal levels of trust in libraries and search engines when it came to meeting their information needs in a way that they felt was authoritative. Seeking to incorporate this insight into our own instructional methodology, Schaffer Library at Union College has attempted to engineer a shift from Google to Google Scholar among our student users by representing Scholar as a viable adjunct to the catalog and to snore traditional electronic resources. By attempting to engage student researchers on their own terms, we have discovered that most of them react enthusiastically to the revelation that the Google they think they know so well is, it turns out, a multifaceted resource that is capable of delivering the sort of scholarly information that will meet with their professors' approval. Specifically, this article focuses on the fact that many Google Scholar searches link hack to our own Web catalog where they identify useful book titles that direct OPAC keyword searches have missed.

    Abstract
    This is the first part of a two-part article that reviews 25 years of published research findings on end-user searching in online information retrieval (IR) systems. In Part 1 (Markey, 2007), the author seeks to answer the following questions: What characterizes the queries that end users submit to online IR systems? What search features do people use? What features would enable them to improve on the retrievals they have in hand? What features are hardly ever used? What do end users do in response to the system's retrievals? Are end users satisfied with their online searches? Summarizing searches of online IR systems by the search features people use everyday makes information retrieval appear to be a very simplistic one-stop event. In Part 2, the author examines current models of the information retrieval process, demonstrating that information retrieval is much more complex and involves changes in cognition, feelings, and/or events during the information seeking process. She poses a host of new research questions that will further our understanding about end-user searching of online IR systems.

    Abstract
    This research investigates how people's perceptions of information retrieval (IR) systems, their perceptions of search tasks, and their perceptions of self-efficacy influence the amount of invested mental effort (AIME) they put into using two different IR systems: a Web search engine and a library system. It also explores the impact of mental effort on an end user's search experience. To assess AIME in online searching, two experiments were conducted using these methods: Experiment 1 relied on self-reports and Experiment 2 employed the dual-task technique. In both experiments, data were collected through search transaction logs, a pre-search background questionnaire, a post-search questionnaire and an interview. Important findings are these: (1) subjects invested greater mental effort searching a library system than searching the Web; (2) subjects put little effort into Web searching because of their high sense of self-efficacy in their searching ability and their perception of the easiness of the Web; (3) subjects did not recognize that putting mental effort into searching was something needed to improve the search results; and (4) data collected from multiple sources proved to be effective for assessing mental effort in online searching.

    Abstract
    This is the second part of a two-part article that examines 25 years of published research findings on end-user searching of online information retrieval (IR) systems. In Part 1, it was learned that people enter a few short search statements into online IR systems. Their searches do not resemble the systematic approach of expert searchers who use the full range of IR-system functionality. Part 2 picks up the discussion of research findings about end-user searching in the context of current information retrieval models. These models demonstrate that information retrieval is a complex event, involving changes in cognition, feelings, and/or events during the information seeking process. The author challenges IR researchers to design new studies of end-user searching, collecting data not only on system-feature use, but on multiple search sessions and controlling for variables such as domain knowledge expertise and expert system knowledge. Because future IR systems designers are likely to improve the functionality of online IR systems in response to answers to the new research questions posed here, the author concludes with advice to these designers about retaining the simplicity of online IR system interfaces.

    Abstract
    Jansen and Pooch review three major search engine studies and compare them to three traditional search system studies and three OPAC search studies, to determine if user search characteristics differ. The web search engine studies indicate that most searchers use two, two search term queries per session, no boolean operators, and look only at the top ten items returned, while reporting the location of relevant information. In traditional search systems we find seven to 16 queries of six to nine terms, while about ten documents per session were viewed. The OPAC studies indicated two to five queries per session of two or less terms, with Boolean search about 1% and less than 50 documents viewed.
