    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
    Will there be a library catalogue in the future and, if so, what will it look like? In the last 25 years, the library catalogue has undergone an evolution, from card catalogues to OPACs, discovery systems and even linked data applications making library bibliographic data accessible on the web. At the same time, users expectations of what catalogues will be able to offer in the way of discovery have never been higher. This groundbreaking edited collection brings together some of the foremost international cataloguing practitioners and thought leaders, including Lorcan Dempsey, Emmanuelle Bermès, Marshall Breeding and Karen Calhoun, to provide an overview of the current state of the art of the library catalogue and look ahead to see what the library catalogue might become. Practical projects and cutting edge concepts are showcased in discussions of linked data and the Semantic Web, user expectations and needs, bibliographic control, the FRBRization of the catalogue, innovations in search and retrieval, next-generation discovery products and mobile catalogues.

    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
    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
    Die Webseite The International CIPAC List (http://cipacs.vfi-online.org/) besteht seit 2001. Sie verzeichnet "card-image public access catalogues" (CIPACs), also Online-Kataloge auf der Basis digitalisierter (gescannter) Zettel- bzw. Bandkataloge. Für Fernleihabteilungen sowie für wissenschaftlich Tätige, die an älterer Literatur interessiert sind, sind derartige Kataloge oft ein unverzichtbares Hilfsmittel, da sich viele Bibliotheken bisher nicht in der Lage sahen, ihre alten Kataloge einer "richtigen" Retrokonversion zu unterziehen. Sie griffen daher zu der vergleichsweise günstigen Alternative, die Katalogkarten zu scannen und mit Hilfe einer geeigneten Software im Web zur Suche anzubieten.

    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
    As of spring semester 2010, Georgia Southern University began using a VuFind implementation as the default access to the library catalogue on the library Web page while maintaining a secondary link to the traditional Voyager "classic" catalogue. VuFind is an open-source product that has been adopted and adapted by all the state universities and colleges in the state of Georgia. For approximately ten years, Georgia libraries have used Voyager as their catalogue, and it remains available to users as the "classic" search option. This report examines the local VuFind implementation compared to the more traditional Voyager implementation, emphasizing the differences in the searching capabilities of each.

    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
    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
    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.

    Abstract
    This study examined how searchers interact with a web-based, faceted library catalog when conducting exploratory searches. It applied multiple methods, including eye tracking and stimulated recall interviews, to investigate important aspects of faceted search interface use, specifically: (a) searcher gaze behavior-what components of the interface searchers look at; (b) how gaze behavior differs when training is and is not provided; (c) how gaze behavior changes as searchers become familiar with the interface; and (d) how gaze behavior differs depending on the stage of the search process. The results confirm previous findings that facets account for approximately 10-30% of interface use. They show that providing a 60-second video demonstration increased searcher use of facets. However, searcher use of the facets did not evolve during the study session, which suggests that searchers may not, on their own, rapidly apply the faceted interfaces. The findings also suggest that searcher use of interface elements varied by the stage of their search during the session, with higher use of facets during decision-making stages. These findings will be of interest to librarians and interface designers who wish to maximize the value of faceted searching for patrons, as well as to researchers who study search behavior.
