    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.

    "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.

    Abstract
    Purpose - The purpose of this paper is to investigate the usability of the user interface to an online catalogue and to explore how user assessment of both system usability and functionality can provide recommendations for the improved design. Design/methodology/approach - Drawing on previous studies, the usability testing used a mixture of search tasks, interviews and a structured focus group. Representative users completed tasks designed to test the system's features and a "think aloud" protocol collected data about the users' responses when using the system and on its perceived functionality. Findings - The analysis of the data on users' evaluation, preferences and expectations by a set of usability attributes enabled recommendations to be made with respect to key areas of the system functionality. Practical implications - The usability study helped to improve the "look and feel" of the interface and demonstrates how the user expectation of what constitutes a supported experience can help make recommendations for the design of a system that is both usable and useful. Originality/value - The paper demonstrates the benefits of using a mixture of approaches to test system usability and to gain a better understanding of usability from the perspective of the system's users, their expectations and perceived usefulness of the system.

    Abstract
    While support for subject searching has been traditionally advocated for in library catalogs, often in the form of a catalog objective to find everything that a library has on a certain topic, research has shown that subject access has not been satisfactory. Many existing online catalogs and discovery services do not seem to make good use of the intellectual effort invested into assigning controlled subject index terms and classes. For example, few support hierarchical browsing of classification schemes and other controlled vocabularies with hierarchical structures, few provide end-user-friendly options to choose a more specific concept to increase precision, a broader concept or related concepts to increase recall, to disambiguate homonyms, or to find which term is best used to name a concept. Optimum subject access in library catalogs and discovery services is analyzed from the perspective of earlier research as well as contemporary conceptual models and cataloguing codes. Eighteen proposed features of what this should entail in practice are drawn. In an exploratory qualitative study, the three most common discovery services used in Swedish academic libraries are analyzed against these features. In line with previous research, subject access in contemporary interfaces is demonstrated to less than optimal. This is in spite of the fact that individual collections have been indexed with controlled vocabularies and a significant number of controlled vocabularies have been mapped to each other and are available in interoperable standards.

    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
    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
    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
    In diesem Artikel geht es um die bisherigen Tests der AK Bibliothek Wien mit dem Discovery System VuFind. Es handelt sich um eine mögliche Alternative zu Primo, einer weit verbreiteten proprietären Suchlösung an österreichsischen Bibliotheken. Nach einem kurzen technischen Überblick wird beschrieben, welche Entwicklungen und Anpassungen vorgenommen werden mussten, um eine Kompatibilität zwischen VuFind und den in der AK Bibliothek vorherrschenden Bedingungen zu schaffen. Dabei wird näher auf die Verarbeitung des Datenformats MAB2 sowie die Schnittstellen zum Bibliothekssystem Aleph und dem Bibliotheks-Repository eingegangen. Die ersten Ergebnisse werden präsentiert und noch zu lösende Probleme angesprochen. Zudem wird ein Ausblick auf zukünftige Vorhaben gegeben.

    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
    In einer 2018 an der Evangelischen Hochschule Nürnberg durchgeführten Studie wurde das Zusammenspiel unterschiedlicher Rechercheinstrumente nach der Einführung eines Resource Discovery Systems ("OPACplus") untersucht. Eine Online-Nutzerbefragung ergab einerseits - trotz verschiedener Probleme - eine große Zufriedenheit sowohl mit dem OPAC als auch mit dem OPACplus, zeigte aber auch, dass das Nebeneinander Schwierigkeiten macht und der OPACplus noch intensiver genutzt werden könnte. Ein Fokusgruppengespräch mit den Mitarbeitenden zeigte u.a., dass der OPACplus besser beworben werden muss. Es werden einige Vorschläge für Verbesserungen der Nutzeroberfläche des OPACplus und eine Marketingstrategie gemacht. Jedoch kann das Resource Discovery System derzeit weder die Fachdatenbanken noch den OPAC vollständig ersetzen.

    Abstract
    Die Arbeitsgruppe PrimoImplementierung des Österreichischen Bibliothekenverbundes evaluierte im Winter 2010/11 Primo Central, den Discovery und Delivery Service von Ex Libris, im Zuge eines dreimonatigen Testzuganges und mehrerer Frage-und-Antwort-Runden mit Produktentwicklern von Ex Libris. Primo Central integriert hunderte Millionen anbieterseitig gelieferter Metadaten zu vornehmlich unselbständiger Literatur mit lokalen Beständen. In Bezug auf viele Forschungsgebiete wurde Primo Central als inhaltsreich empfunden, hauptsächlich hinsichtlich wissenschaftlicher Zeitschriftenaufsätze. Es deckte die Bestände einer großen und einer mittleren Universaluniversitätsbibliothek gut ab. Das Fehlen nationaler (deutschsprachiger) und regionaler Titel schränkt die Anwendbarkeit für Suchen nach österreichischem und deutschem Recht wesentlich, für Suchen in den Bereichen Wirtschaft, Psychologie und Bauingenieurwesen teilweise ein. Primo Central wird regelmäßig aktualisiert, ist jedoch notwendigerweise weniger aktuell als Verlagsplattformen oder PubMed, demzufolge auch weniger aktuell als Federated Search-Systeme wie MetaLib. Die dauerhafte Verfügbarkeit von Datenquellen in Primo Central kann von Ex Libris nicht garantiert werden. Die Metadaten der in Primo Central indexierten Ressourcen kommen derzeit nur zu einem geringen Teil vom Verlag selbst (der Großteil über CrossRef und IngentaConnect ), und enthalten daher oft keine inhaltliche Erschließung. Die Suchmöglichkeiten und die Reihung der Treffer nach Relevanz sind vergleichbar mit Google Scholar. Zusätzliche Funktionalitäten von Primo Central betreffen die Möglichkeit der Facettierung der Suchergebnisse und die Einschränkung der Treffer auf an der jeweiligen Bibliothek verfügbare Volltexte. Die Implementierung von Primo Central verlief schnell und problemlos. Voraussetzungen für den Einsatz von Primo Central sind die Verwendung von Promo als Bibliothekssuchmaschine oder von MetaLib als Federated Search System und der Einsatz eines Link Resolvers (nicht zwingend SFX).

    Abstract
    The construction and updating of indexing languages depend on the organization of their hierarchical structures in order to determine the classification of related terms and, above all, to allow a constant updating of vocabulary, a condition for knowledge evolution. The elaboration of an indexing language for online catalogs of libraries' networks is important considering the diversity and specificity of knowledge areas. From this perspective, the present paper reports on the work of a team of catalogers and researchers engaged in the construction of a hierarchical structure of an indexing language for an online catalog of a university library's network. The work on hierarchical structures began by defining the categories and subcategories that form the indexing language macrostructure by using the parameters of the Library of Congress Subject Headings , the National Library Terminology and the Vocabulary of the University of São Paulo Library's system. Throughout the stages of the elaboration process of the macrostructure, difficulties and improvements were observed and discussed. The results enabled the assessment of the hierarchical structures of the languages used in the organization of the superordinate and subordinate terms, which has contributed to the systematization of operational procedures contained in an indexing language manual for online catalogs of libraries.
