    Abstract
    Die enge Zusammenarbeit der vier Berliner Universitätsbibliotheken1 reicht weit zurück. Bereits vor der Jahrtausendwende haben die Berliner Universitätsbibliotheken (UBs) gemeinsam das Bibliothekssystem Aleph 500 ausgewählt und implementiert, danach folgten weitere Systeme - das Linking System SFX, die Digitale Bibliothek MetaLib und das Bibliotheksportal Primo. Es war daher folgerichtig und selbstverständlich, dass auch die Auswahl und Implementierung eines neuen Bibliothekssystems in enger Abstimmung und Zusammenarbeit erfolgte. Die Erfahrungen bei Vertragsverhandlungen und Implementierung von Alma sind Gegenstand des folgenden Berichtes.

    Abstract
    Zum Wintersemester 2010/11 wurde von der Universitätsbibliothek der Freien Universität Berlin das neue Bibliotheksportal Primo eingeführt, das auf der gleichnamigen Software der Firma Ex Libris basiert. Zunächst in einem "soft launch" als Betaversion live geschaltet, soll es in naher Zukunft den derzeitigen Katalog und die Digitale Bibliothek als Suchoberflächen ersetzen. Diese Situation bot einen optimalen Ausgangspunkt für eine Studie zur Usability des neuen Portals, da deren Ergebnisse direkt in die Neugestaltung der Relaunch-Version einfließen können. Um verschiedene Arten von Usability-Problemen des Bibliotheksportal Primo zu identifizieren, haben sich die Autorinnen einer Methodenkombination bedient. Zum einen wurde eine Heuristische Evaluation und zum anderen 20 Usability-Tests der deutschsprachigen Oberfläche des Portals durchgeführt. Die detaillierte Darstellung der so festgestellten Usability-Probleme bildet den Kern der Arbeit. Als Basis für das Verständnis des Systems und der methodischen Vorgehensweise, wird außerdem Primo im Kontext der "Neuen Kataloge" und deren Funktionalitäten näher beleuchtet, sowie die theoretischen Grundlagen der in der Arbeit verwendeten Methoden der Usability-Evaluation dargestellt.

    Abstract
    The quality of large catalogs is uneven and often low, but this issue is underrated and understudied. Library catalogs often fail to communicate correct and clear information to users and their low quality is not simply due to faults, duplications, and so on but also to unwise cataloging standards and policies. While there is plenty of uncontrolled information about books and other publications, the need for good-quality bibliographic information is apparent and library catalogs may provide a trustworthy map of the publishing output, with full control of editions, works, authors, and so on and effective navigation functions, which are lacking in today's information-rich environment.

    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
    Although technology can often correct spelling errors, the complex tasks of information searching and retrieval in an online public access catalog (OPAC) are made more difficult by these errors in users' input and bibliographic records. This study examines the search behaviors of 38 university students, divided into groups with either easy-to-spell or difficult-to-spell search terms, who were asked to find items in the OPAC with these search terms. Search behaviors and strategy use in the OPAC and on the World Wide Web (WWW) were examined. In general, students used familiar Web resources to check their spelling or discover more about the assigned topic. Students with difficult-to-spell search terms checked spelling more often, changed search strategies to look for the general topic and had fewer successful searches. Students unable to find the correct spelling of a search term were unable to complete their search. Students tended to search the OPAC as they would search a search engine, with few search terms or complex search strategies. The results of this study have implications for spell checking, user-focused OPAC design, and cataloging. Students' search behaviors are discussed by expanding Thatcher's (2006) Information-Seeking Process and Tactics for the WWW model to include OPACs.

    Abstract
    Enhancing content description of specialized resources, particularly astronomical resources, is a matter that is still unresolved in library and information science. In this paper, the authors outline deficiencies in some fields and elements of cataloging standards for description of historical astronomical resources, mainly star atlases and catalogs. Furthermore, they review their recent proposal of astronomical parameters for a better description and propose an approach for accommodating these parameters in the current criteria of MARC 21, the International Standard Bibliographic Description, and Resource Description and Access. Fourteen new parameters are considered, and recommendations are provided to standards developers for the addition of elements to accommodate attributes of celestial cartographic resources. This would improve bibliographic records for such resources in astronomical libraries' OPACs, which will have a beneficial effect on information retrieval.

    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
    Many experts have proposed an evolution toward "next generation catalogs," whose main features are partly inspired by commercial websites such as Google or Amazon. This article examines pros and cons of this integration. It also aims to show how a qualitative approach helps to broaden understanding of web communication mechanisms. After discussing some examples of "next generation catalog" features, I analyze the interface of an online catalog responding to different users' information needs and seeking behaviors. In the conclusion I suggest that the right approach to integration is a "translation" (not a "copy and paste") between commercial and library logics.

    Abstract
    An increasing number of library user studies are employing ethnographic techniques as an alternative to more traditional qualitative methods such as surveys. Such techniques, however, are only beginning to see significant application to catalog user studies. Beginning with a discussion of the applied ethnographic method and its current usage within the field of Library and Information Science research, this article will assess methods that have traditionally been applied to studies of catalog users and present the case for the potential of an ethnographic approach for future catalog evaluation and design.

    Abstract
    Controlled vocabulary and subject headings in OPAC records have proven to be useful in improving search results. The authors used a survey to gather information about librarian opinions and professional use of controlled vocabulary. Data from a range of backgrounds and expertise were examined, including academic and public libraries, and technical services as well as public services professionals. Responses overall demonstrated positive opinions of the value of controlled vocabulary, including in reference interactions as well as during bibliographic instruction sessions. Results are also examined based upon factors such as age and type of librarian.

    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.

    Abstract
    The aim of the research undertaken was to get to know the degree of implementation of discovery tools in university libraries in the Iberian Peninsula. It also allowed an initial evaluation of the facilities offered by the tools implemented. With regard to the presence of discovery tools we find a different situation in the two countries, with a higher degree of implementation in Spain. As for the behaviour of the discovery layers, the eight tools evaluated performed appropriately. Discovery tools represent a considerable advance. The combining of the library's catalogue and indexes to articles with other sources of information in a single unified interface is an unquestionable improvement. However, catalogues and databases still fulfil some purposes better than discovery tools. Libraries need to consider their clients when putting up on their websites the various tools for gaining access to contents.

    Abstract
    "Frau Wiesmüller möge mir verzeihen, aber was sie da mit Bellinda Woppada zur Katalogisierung in öffentlichen Bibliotheken zusammengeschrieben hat, ist für mich aus Benutzersicht ziemlich uninteressant. Es gibt bisher kaum Literatur zu diesem Thema, das aber nach Ansicht der Autorinnen wichtiger ist als es scheint. Meine These lautet: Es muss für BenutzerInnen katalogisiert werden, aber schon ein sehr sehr kurzer Blick auf einige OPACs macht deutlich, wieviel da im Argen liegt. Zu den einzelnen Medien sollte möglichst viel Information als Entscheidungshilfe vorliegen, und das kann nur durch viel mehr Kooperation der Bibliotheken realisiert werden. Die Optik ist meist katastrophal. Die OPACs geben sich ästhetisch abschreckend auf dem Stand der 1990er Jahre, Coverbilder gibt es weniger, als ich gedacht hätte."

    Abstract
    Documents in digital and paper libraries may be arranged, based on their topics, in order to facilitate browsing. It may seem intuitively obvious that ordering documents by their subject should improve browsing performance; the results presented in this article suggest that ordering library materials by their Gray code values and through using links consistent with the small world model of document relationships is consistent with improving browsing performance. Below, library circulation data, including ordering with Library of Congress Classification numbers and Library of Congress Subject Headings, are used to provide information useful in generating user-centered document arrangements, as well as user-independent arrangements. Documents may be linearly arranged so they can be placed in a line by topic, such as on a library shelf, or in a list on a computer display. Crossover links, jumps between a document and another document to which it is not adjacent, can be used in library databases to allow additional paths that one might take when browsing. The improvement that is obtained with different combinations of document orderings and different crossovers is examined and applications suggested.

    Abstract
    The discovery service (a search engine and service called WILBERT) used at our library at the Technical University of Applied Sciences Wildau (TUAS Wildau) is comprised of more than 8 million items. If we were to record all licensed publications in this tool to a higher level of articles, including their bibliographic records and full texts, we would have a holding estimated at a hundred million documents. A lot of features, such as ranking, autocompletion, multi-faceted classification, refining opportunities reduce the number of hits. However, it is not enough to give intuitive support for a systematic overview of topics related to documents in the library. John Naisbitt once said: "We are drowning in information, but starving for knowledge." This quote is still very true today. Two years ago, we started to develop micro thesauri for MINT topics in order to develop an advanced indexing of the library stock. We use iQvoc as a vocabulary management system to create the thesaurus. It provides an easy-to-use browser interface that builds a SKOS thesaurus in the background. The purpose of this is to integrate the thesauri in WILBERT in order to offer a better subject-related search. This approach especially supports first-year students by giving them the possibility to browse through a hierarchical alignment of a subject, for instance, logistics or computer science, and thereby discover how the terms are related. It also supports the students with an insight into established abbreviations and alternative labels. Students at the TUAS Wildau were involved in the developmental process of the software regarding the interface and functionality of iQvoc. The first steps have been taken and involve the inclusion of 3000 terms in our discovery tool WILBERT.
