- Abstract
- Bibliotheken sind nicht chaotische Sammlungen von Medien, sondern werden stets als Information-Retrieval-Systeme implementiert, denn das Wiederfinden bei exakten und vor allem bei vagen Anfragen ist von Anfang an das Sammlungsziel. Niemand kennt zum Zeitpunkt der Sammlung die Fragestellung, die einen zukünftigen Benutzer zu diesem Medium führen wird. Die Art der Sammlungsorganisation bestimmt in hohem Maße die zukünftig mögliche Antwortmenge und deren informatorische Qualität. Der Siegeszug der digitalen Information-Retrieval-Systeme im Internet hat in den letzten zehn Jahren Erwartungen und Märkte geschaffen, die weder Karteikarten, noch deren digitales Ebenbild, die heutigen Bibliotheksmanagement-Systeme befriedigen können. Es genügt nicht mehr, dass Google und andere kostenlos das aufsammeln und nachweisen, was im Internet frei zugänglich ist. Alte, noch »marktfähige« Inhalte werden neu aufbereitet, mit neuen Inhalten kombiniert, um neue Geschäftsfelder zu schaffen. Es geht um Verdrängung und Neuverteilung, und die älteren Inhalte der Bibliotheken sind meist noch hinreichend »marktfähig«.

- Abstract
- This paper describes a survey on how system vendors and libraries handled tagging in OPACs and discovery layers. Tags are user added subject metadata, also called folksonomies. This survey also investigated user behavior when they face the possibility to tag. The findings indicate that legacy/classic systems have no tagging capability. About 47% of the discovery tools provide tagging function. About 49% of the libraries that have a system with tagging capability have turned the tagging function on in their OPACs and discovery tools. Only 40% of the libraries that turned tagging on actually utilized user added subject metadata as access point to collections. Academic library users are less active in tagging than public library users.

- 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.

- 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.

- 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
- Wir beschreiben den Prototypen einer Webanwendung, die zwei unterschiedliche Discovery-Dienste und einen OPAC-basierten Suchmaschinenindex integriert. Zunächst skizzieren wir die technische Architektur, geben dann einen Überblick über die Metadaten und APIs der eingesetzten Discovery-Dienste und berichten im Anschluss von den Nutzererfahrungen, die wir aus dem Feedback der Testpersonen gewonnen haben. Zuletzt geben wir einen Überblick über die Ergebnisse unseres Tests und umreißen die Richtung, in die wir unsere Entwicklung fortführen wollen.

- Abstract
- Dewey Decimal Classification has been used to organize materials owned by the three scientific libraries at the University of Pavia, and to allow integrated browsing in their union catalogue through SciGator, a home built web-based user interface. Classification acts as a bridge between collections located in different places and shelved according to different local schemes. Furthermore, cross-discipline relationships recorded in the system allow for expanded queries that increase recall. Advantages and possible improvements of such a system are discussed.

- Abstract
- Bibliotheken stehen heute mehr denn je vor der Frage, wie sie ihre Dienste attraktiv gestalten können. Da liegt es nahe, Nutzerinnen und Nutzer aktiv in den Designprozess einzubinden. Die Neuentwicklung des KOBV-Portals (http://portal.kobv.de), einer regionalen Suche über die Bestände der Bibliotheken in Berlin und Brandenburg, geht konsequent den Weg des Co-Designs. Nutzerinnen und Nutzer werden als Entwicklungspartner verstanden. Als Projektpartner wurde das Institut für Bibliotheks- und Informationswissenschaft (IBI) der Humboldt-Universität zu Berlin gewonnen.

- Abstract
- Nach einschlägigen Fortbildungsveranstaltungen in Stuttgart in den Jahren 2004 und 20071 beschäftigte sich der Regionalverband Südwest des Vereins Deutscher Bibliothekare (VDB) bereits zum dritten Mal in einer Vortragsveranstaltung mit aktuellen und zukünftigen Entwicklungen bei Bibliothekskatalogen: "Der Katalog der Zukunft (Teil 3): Die Benutzer in den Mittelpunkt!" war der Titel der Veranstaltung am 11. November 2010. Gastgeber war - wie schon bei der Premiere der Veranstaltungsreihe im Jahr 2004 - die Universitätsbibliothek Stuttgart. Da der Landesverband Baden-Württemberg des Berufsverband Information Bibliothek (BIB) ebenfalls an der Thematik interessiert war, bot es sich an, die Fortbildung gemeinsam durchzuführen. Zugleich sollte damit ein Zeichen für eine engere Kooperation der beiden Berufsverbände gesetzt werden. Entsprechend wurde auch die Moderation geteilt: Vormittags moderierte Heidrun Wiesenmüller von der Stuttgarter Hochschule der Medien (VDB Südwest), nachmittags Isabell Leibing von der Bibliothek der Universität Konstanz (BIB Baden-Württemberg). Die Vortragsfolien und weitere Materialien können über die Websites des VDB-Regionalverbands Südwest und der BIB-Landesgruppe Baden-Württemberg abgerufen werden.
