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

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

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

Since around 2005 several striking attempts have been made to rethink the design of library catalogs in production systems; the North Carolina State University's (NCSU) Endeca catalog being a notable example. These developments are taking place just as the continued relevance of traditional cataloging is being questioned. This article examines the relationship of these new designs to evolving cataloging practice and the changing discovery environment.

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

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 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

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

Subject access to bibliographic data supported by knowledge organization systems, such as subject headings and classification, plays an important role in ensuring the quality of library catalogues. It is generally acknowledged that users have a strong affinity to subject browsing and searching and are inclined tofollow meaningful links between resources. Research studies, however, show that library OPACs are not designed to support or make good use of subject indexes and their underlying semantic structure. A project entitled OPAC semantici was initiated in 2003 by a number of Italian subject specialists and the Italian "Research Group on Subject Indexing" (GRIS) with a goal to analyse and evaluate subject access in Italian library catalogues through a survey of 150 OPACs. Applying the same methodology, a follow-up survey to assess whether any improvement had taken place was conducted five years later, in spring 2008. Analysis of these two surveys indicated that there was a slight improvement. The authors discuss the results of these two surveys, analyse the problems in subject searching in OPACs and explain the recommendations for subject searching enhancement put forward by GRIS. Using the example of Italian OPACs, the authors will attempt to outline some requirements for a subject searching interface and explain how this can be achieved through authority control.

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

Mit der Einführung der neuen Suchmaschine Primo im Österreichischen Bibliothekenverbund wurde eine Neubewertung und Neuausrichtung der Anzeige, Indexierung und der erstmals möglichen Facettierung sacherschließender Elemente notwendig. Nach einem kurzen Überblick über die im Verbund zum Einsatz kommende Software sowie über Umfang und Art der inhaltlichen Erschließung im zentralen Katalog wird detailliert auf die angestrebte Umsetzung derselben in der neuen Suchmaschinenumgebung eingegangen, wobei der verbalen Erschließung durch RSWK-Ketten als wichtigste Form der intellektuellen Erschließung erhöhte Aufmerksamkeit zukommt. In einem zweiten Teil wird die konkrete technische Umsetzung in Primo beleuchtet, um abschließend einen Ausblick auf zukünftige Entwicklungen sowie projektierte Verbesserungen zu geben.

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

Im digitalen Zeitalter erschöpft sich das Aufgabenspektrum der Archive, Bibliotheken und Museen längst nicht mehr in der Sammlung, Erschließung, Bewahrung und Zugänglichmachung physischer Sammlungsbestände. Es bezieht die Digitalisierung ebenso mit ein wie die Zusammenführung der Digitalisate in übergreifenden Internetportalen. Der folgende Beitrag bietet einen Überblick zum Einsatz der Open-Source-Software VuFind, welche als Discovery-Tool für digitalisierte Kulturgüter vorgestellt wird. Erläutert werden nicht nur die Anforderungen, die sich für die Erschließung und das Metadatenmanagement ergeben, sondern auch die Chancen einer engeren Kooperation von Archiven, Bibliotheken und Museen im digitalen Zeitalter. Abgerundet wird der Beitrag um Ausführungen zum Portal digitales thüringen, welches die Anwendung VuFind-basierter Discovery-Technologie im Kontext der Digitalisierung von Kulturgut beispielhaft illustriert.

Abstract

eBooks on Demand (EOD) ist ein europaweites Netzwerk von mehr als 30 Bibliotheken in 12 europäischen Ländern mit dem Ziel, urheberrechtsfreie Bücher auf Anfrage zu digitalisieren und zur Verfügung zu stellen. Zur Digitalisierung kann jedes Buch bestellt werden, das im Online-Katalog der Bibliothek mit dem sog. EOD-Button versehen ist. Das so bestellte Buch wird dann innerhalb weniger Tage hochauflösend gescannt und nach erfolgreicher Bezahlung als PDF mit hinterlegtem OCR-Text zur Verfügung gestellt. Bisher musste in jedem einzelnen Katalog jeder teilnehmenden Bibliothek separat gesucht werden, um ein bestimmtes Buch zu finden. Seit Ende 2010 wird nun unter der Adresse http://search.books2ebooks.eu eine bibliotheksübergreifende Suchmaschine angeboten, die mit der Open Source Software VuFind realisiert wurde. Derzeit werden hier 1,8 Mio. Datensätze von 12 Bibliotheken durchsuchbar gemacht. Den NutzerInnen der bibliotheksübergreifenden Suchmaschine wird so schnell und unkompliziert Zugang zu bereits digitalisierten Werken als auch Büchern, die zur Digitalisierung auf Anfrage zur Verfügung stehen, gegeben.

Abstract

Wissenschaftliche Bibliotheken stehen seit zehn Jahren vor der Frage, ob sie für die Vermittlung ihrer Bestände Discovery-Systeme oder Internet-Suchmaschinen wie Google Scholar einsetzen sollen. Ein Vergleich des Discovery-Systems Primo des Anbieters Ex Libris mit Google Scholar zeigt, dass Primo eine bessere Usability bietet, indem es summa summarum einfacher zu bedienen ist sowie relevantere und vielfältigere Treffer liefert.

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

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.
