    Abstract
    To become lifelong learners, students must acquire information retrieval skills for future as well as current information needs. Describes how the library use instruction programme at Northwest Missouri State University incorporates a heuristic model in which students continually evaluate and refine their information seeking practices while progressing through all levels of courses in diverse disciplines. Collegial partnerships with departmental faculty and ongoing instructional assessment are essential to the success of the programme

    "In einer öffentlichen Bücherei ist die Suche nach einem Werk recht einfach: Man geht einfach die Regale ab, bis man beim richtigen Buchstaben oder Thema angekommen ist. In vielen wissenschaftlichen Bibliotheken ist das komplizierter. Denn dort müssen sich Studenten durch Datenbanken und Zettelkataloge wühlen. "Eine Ausnahme ist der Lesesaal, erklärt Marlene Grau, Sprecherin der Staats- und Universitätsbibliothek in Hamburg. Im Lesesaal stehen die Bücher wie in einer öffentlichen Bibliothek in Reih und Glied nach Fachgebieten wie Jura, Biologie oder Medizin sortiert. So können Studenten ein wenig schmökern und querbeet lesen. Wer jedoch ein bestimmtes Werk sucht, nutzt besser gleich den Katalog der Bibliothek. Darin lässt sich zum einen nach dem Autor oder einem Titelstichwort suchen - in der Biologie etwa "Fliege" oder "Insekt". "Dann kann man hoffen, dass Bücher zum Thema das Stichwort im Titel enthalten", sagt Grau. Die andere Variante ist, nach einem Schlagwort zu suchen. Um das passende zu finden, kann man im Schlagwort-Index blättern. Oder man sucht nach einem bekannten Buch, das zum Thema passt. Dann kann man mit dessen Schlagwörtern weitersuchen. Der Vorteil: Bücher müssen dieses Schlagwort nicht im Titel enthalten. Buchtitel wie 'Keine Angst vor Zahlen' oder 'Grundkurs Rechnen' findet man über die Schlagworte 'Mathematik' und 'Einführung', aber mit Stichworten eher nicht", erklärt Ulrich Hohoff. Er leitet die Universitätsbibliothek in Augsburg.
    Im Online-Katalog erfahren Studenten auch, ob das Buch verfügbar oder verliehen ist. Ist es gerade vergriffen, kann man es vormerken lassen, er- klärt Monika Ziller, Vorsitzen- de des Deutschen Bibliotheksverbands in Berlin. Dann werden die Studenten entsprechend benachrichtigt, wenn es zurückgegeben wurde. Außerdem könnten Studenten virtuelle Fachbibliotheken nutzen, erklärt Grau. Um das Thema Slavistik kümmert sich etwa die Staatsbibliothek in Berlin. Auf der Internetseite kann man über Suchbegriffe alle elektronischen Slavistik-Angebote wie Zeitschriften, E-Books oder Bibliografien durchforsten. Die virtuelle Fachbibliothek spuckt dann eine Titelliste aus. Bestenfalls können Studenten gleich auf einzelne Volltexte der Liste zugreifen. Oder sie müssen schauen, ob die eigene Bibliothek das gesuchte Werk hat. Vor allem Zeitschriften sind oft online im Volltext abrufbar, aber auch Enzyklopädien. "Die sind auch aktueller als der Brockhaus von 1990, der zu Hause im Regal steht" sagt Grau. Manchmal ließen sich die Texte aus Gründen des Urheberrechts aber nur auf den Rechnern auf dem Unicampus lesen, ergänzt Hohoff. Findet man ein Buch nicht, ist der Grund dafür oft ein Fehler, der sich bei der Suche eingeschlichen hat. Das fängt bei der Rechtschreibung an: "Bibliothekskataloge verfügen über keine fehlertolerante Suche wie Google", erklärt Ziller.
    "Ein häufiger Fehler ist auch, bei Google nach Büchern zu suchen", sagt Grau. Die Suchmaschine enthält keine Bibliotheksdaten. Außerdem sollten Studenten darauf achten, ob sie nach einem Zeitschriften-Artikel oder einer Monografie suchen. Benötigt man einen Aufsatz, muss man nach dem Titel der Zeitschrift und nicht nach dem Titel des Artikels suchen. Wichtig ist auch, den Suchschlüssel zu beachten. Wer nach dem Autor Johann Wolfgang von Goethe sucht, aber das Wort in der Titelsuche eingibt, bekommt andere Treffermengen. Studenten sollten die Suche auch nicht zu sehr eingrenzen. "Dann findet man nichts", warnt Grau. Andererseits darf man auch nicht zu allgemein suchen. Wer nach einem Buch zur deutschen Geschichte sucht, bekommt bei der Eingabe von "deutsche Geschichte" Tausende Treffer. "Da muss man den richtigen Suchschlüssel auswählen", erklärt Grau. Wer im Feld "Titelanfänge" etwa "deutsche Geschichte" eingibt, finde alle Titel mit diesen Wörtern in genau dieser Reihenfolge. Er lande also nicht beim Buch "Deutsche Naturlyrik: ihre Geschichte in Einzelanalysen". Das ist bei weit gefassten Begriffen sehr wichtig und hilfreich."

    Abstract
    This paper desctibes a study of undergraduate student search behavlour, examines the results through the lens of various disciplines, and provides now insights that will increase our understanding and facilitate the development of mom effetive instructional programmes Perspectives and research results drawn from multiple disciplines are used to explore the role of mental modele, reference groups and habits, and IntelIectual development in the search behaviour demonstrated by the undergraduate students. During interviews conducted as part of the study, many students were able to articulate the importance of source evaluation and describe electronically-appropriate methods for assessing the authority and reliability of Weh based information resources. In practice, however, these students frequently abandoned source evaluation altogether and, following the path of Ieast resistance, relied exclusively on basic Google searching, This approach both compromiscd the quality of their search results and contributed to frustration with the research process. This may not be extraordinarily unusual behaviour, but it is cause for considerable concern among Information literacy programme planners and Instructors. Discussion of the study results and related research is followed by pragmatic suggestions for modifylng ineffective search behaviour through emhanced instructional programmes

    Abstract
    In recent years, searching the web on mobile devices has become enormously popular. Because mobile devices have relatively small screens and show fewer search results, search behavior with mobile devices may be different from that with desktops or laptops. Therefore, examining these differences may suggest better, more efficient designs for mobile search engines. In this experiment, we use eye tracking to explore user behavior and performance. We analyze web searches with 2 task types on 2 differently sized screens: one for a desktop and the other for a mobile device. In addition, we examine the relationships between search performance and several search behaviors to allow further investigation of the differences engendered by the screens. We found that users have more difficulty extracting information from search results pages on the smaller screens, although they exhibit less eye movement as a result of an infrequent use of the scroll function. However, in terms of search performance, our findings suggest that there is no significant difference between the 2 screens in time spent on search results pages and the accuracy of finding answers. This suggests several possible ideas for the presentation design of search results pages on small devices.

    Abstract
    The study reported in this paper is part of a programme of ongoing research based on the model of the Information Search Process (ISP) developed in a series of prior studies by Kuhlthau. This study sought to gain a better understanding of the variety of tasks that involve lawyers as a particular group of information workers, how they use information to accomplish their work, and the role mediators play in their process of information seeking and use. Findings revealed that these lawyers frequently were involved in complex tasks that required a constructive process of interpreting, learning and creating. To accomplish these complex tasks, they preferred printed texts over computer databases primarily because computer databases required well-specified requests and did not offer an option for examining a wide range of information at one time. These lawyers called for an active potential role for mediators in 'just for me' services. 'Just for me' services would encompass designing systems to provide a wider range of access more compatible with the process of construction, applying and developing principles of classification that would offer a more uniform system for organising and accessing files, and providing direction in filtering the overwhelming amount of information available on electronic resources.

    Abstract
    Purpose Web search is more and more moving into mobile contexts. However, screen size of mobile devices is limited and search engine result pages face a trade-off between offering informative snippets and optimal use of space. One factor clearly influencing this trade-off is snippet length. The purpose of this paper is to find out what snippet size to use in mobile web search. Design/methodology/approach For this purpose, an eye-tracking experiment was conducted showing participants search interfaces with snippets of one, three or five lines on a mobile device to analyze 17 dependent variables. In total, 31 participants took part in the study. Each of the participants solved informational and navigational tasks. Findings Results indicate a strong influence of page fold on scrolling behavior and attention distribution across search results. Regardless of query type, short snippets seem to provide too little information about the result, so that search performance and subjective measures are negatively affected. Long snippets of five lines lead to better performance than medium snippets for navigational queries, but to worse performance for informational queries. Originality/value Although space in mobile search is limited, this study shows that longer snippets improve usability and user experience. It further emphasizes that page fold plays a stronger role in mobile than in desktop search for attention distribution.

    Abstract
    Mittels professioneller Suchtechniken lässt sich die Recherche im WWW wesentlich schneller und zuverlässiger gestalten. Selbst eine universelle Suchmaschine, wie Google, erlaubt mittels spezieller Suchfunktionen qualifizierte Recherchen über den Freitext hinaus. Von besonderer Bedeutung sind hier die Selektion nach Domainnamen und die Einbeziehung der URL. In Kombination mit dem Verständnis der Ranking-Techniken, z. B. der Prioritäten der im HTML-Quelltext verankerten inhaltlichen Meta-Informationen (Title-Tag, Meta-Tags Keywords, Description) gegenüber dem Standardverfahren (Google PageRank) lässt sich die Recherche auf professionelle Informationsangebote ausrichten. Eine weitere Qualifizierung lässt sich durch geschickten Einsatz der Phrasensuche erreichen. In jedem Fall setzt eine erfolgreiche Recherche, auch bei scheinbar einfachen Benennungen und Zusammenhängen eine intellektuelle Recherchevorbereitung voraus - bei der zunächst das Thema strukturiert und dann eine Vorstellung über die möglichen Zusammenhänge entwickelt wird, in der die Zielinformation im WWW zu finden sein könnte. Soweit die Möglichkeit besteht, sollte bei anspruchsvollen technischwissenschaftlichen Themen der WWW-Suche eine Recherche in professionellen Literaturdatenbanken vorausgehen. Diese haben den Vorzug, dass eine transparente und sorgfältig selektierte Quellenbasis vorliegt und durch Suche mit kontrolliertem Wortschatz die typischen Unschärfen einer Freitextrecherche (unerwünschte Zusammenhänge, Synonyme, Homonyme, Schreibvarianten usw.) umgangen werden können. Die FIZ-Technik-Inform GmbH bietet kostenpflichtige Weiterbildungsveranstaltungen auch zur WWW-Recherche an.
