Abstract

Suchmaschinen befinden sich einerseits in einem beständigen Wandel. Andererseits gibt es immer wieder Entwicklungen, die die Suche "auf eine neue Ebene" heben. Eine solche Entwicklung, die wir zurzeit erleben, wird unter dem Label "Next Generation Search Systems" geführt. Der Begriff fasst die Veränderungen durch eine Vielfalt von Geräten und Eingabemöglichkeiten, die Verfügbarkeit von Verhaltensdaten en masse und den Wandel von Dokumenten zu Antworten zusammen.

Abstract

If the public library catalogue is to continue to have relevance to its users, it needs to move beyond its current inventory model, where all content is designed and controlled by library staff and client interaction with catalogue content is limited, to a social catalogue, where users can contribute to, and interact with information and with each other. The goal of this report is to present the results of an analysis of four months worth of log analysis of two social discovery systems used in two Canadian public libraries to examine: (a) how public library users interact with social discovery systems; (b) how usage compares between the two social discovery systems; and (c) whether the use of the features in social discovery systems is consistent over time. Results suggest that clients are making limited use of the social features of the system that allow them to interact with the catalogue records and with one another.

Abstract

Information seeking is a fundamental human activity. In the modern world, it is frequently conducted through interactions with search systems. The retrieval and comprehension of information returned by these systems is a key part of decision making and action in a broad range of settings. Advances in data availability coupled with new interaction paradigms, and mobile and cloud computing capabilities, have created a broad range of new opportunities for information access and use. In this comprehensive book for professionals, researchers, and students involved in search system design and evaluation, search expert Ryen White discusses how search systems can capitalize on new capabilities and how next-generation systems must support higher order search activities such as task completion, learning, and decision making. He outlines the implications of these changes for the evolution of search evaluation, as well as challenges that extend beyond search systems in areas such as privacy and societal benefit.

Abstract

Library of Congress Subject Headings (LCSH), the standard subject language used in library catalogues, are often criticized for their lack of currency, biased language, and atypical syndetic structure. Conversely, folksonomies (or tags), which rely on the natural language of their users, offer a flexibility often lacking in controlled vocabularies and may offer a means of augmenting more rigid controlled vocabularies such as LCSH. Content analysis studies have demonstrated the potential for folksonomies to be used as a means of enhancing subject access to materials, and libraries are beginning to integrate tagging systems into their catalogues. This study examines the utility of tags as a means of enhancing subject access to materials in library online public access catalogues (OPACs) through usability testing with the LibraryThing for Libraries catalogue enhancements. Findings indicate that while they cannot replace LCSH, tags do show promise for aiding information seeking in OPACs. In the context of information systems design, the study revealed that while folksonomies have the potential to enhance subject access to materials, that potential is severely limited by the current inability of catalogue interfaces to support tag-based searches alongside standard catalogue searches.

Abstract

This article examines the benefits of a Resource Description and Access (RDA) enrichment project for libraries. Enrichment projects "hybridize", or enrich legacy Anglo-American Cataloguing Rules, Second Edition (AACR2) bibliographic records with RDA data. Until a replacement for MARC is developed, bibliographic data will continue to be encoded in MARC 21 in many integrated library systems. Library catalogs contain records coded under both AACR2 and RDA standards. RDA enrichment projects benefit the patron experience because the data is cleaner and more consistent for patron use and display, cataloging staff workflows are simplified, and the consistency of the data is advantageous for system development and data exchange with other communities

Abstract

Shifting library catalogs from physical to digital has come at a cost. Catalog records no longer leave traces of their own evolution, which is a loss for librarianship. The subjective nature of information classification warrants self-examination, within which we may see the evolution of practice, debates over attribution and relevance, and how culture is reflected in the systems used to describe it. Wikipedia models what is possible: revision histories and discussion pages function as knowledge generators. A list of unanswerable questions for the modern catalog urges us to construct a new, forward-thinking bibliography that allows us to look backward.

Abstract

Seit Einführung der neuen Discovery-Kataloge stehen unseren Nutzerinnen und Nutzern zusätzlich Millionen von Dokumenten neben dem lokalen Buchbestand zur Verfügung. Diese Zielgruppe muss in die Lage versetzt werden, die für sie relevanten Titel einfach und sicher zu finden. Die Qualität von Empfehlungsfunktionen und besonders der Relevanz-Ranking-Methoden sind daher für den Erfolg eines Discovery-Systems besonders wichtig. Das Ranking bibliothekarischer Suchmaschinentechnik ignoriert bisher das Feedback durch Nutzerinnen und Nutzer. Die Staats- und Universitätsbibliothek Bremen (SuUB) setzt mit dem in Bremen entwickelten Discovery-System "E-LIB" seit Sommer 2011 zusätzlich auf eine Modifikation des Treffer-Rankings über Popularitätsfaktoren der Medien wie Klickstatistik, Auflagen- und Exemplarzahl. Die maßgeschneiderte Entwicklung eines eigenen Bibliothekskataloges, den die SuUB seit 2004 mit dem Discovery-System "E-LIB" in Bremen betreibt, erlaubt die schnelle und flexible Anpassung von Retrievalfunktionen an die Bedürfnisse der Nutzerinnen und Nutzer vor Ort.

Abstract

Next-generation catalogues can be viewed as the latest manifestation of a tendency in library catalogue history to strive for centralization of access to collections-a single portal for the discovery of library resources. Due to an increasing volume of published materials and the explosion of online information resources during the Internet age, the library does not currently provide centralized access to its various information silos, nor does it provide a user-friendly search and retrieval experience for users whose expectations are shaped by Google and other major commercial Web sites. Searching across library resources is a complicated task, bearing high-attention "transaction costs" for the user, which discourage the use of library resources. Libraries need access systems that minimize complexity, easing discovery and delivery of resources for user populations. Here, the authors review past efforts of centralization of access, consider the potential of next-generation catalogues in the context of this historical tendency toward centralization of access, and describe what goals underlie that centralization.

Abstract

To improve resource discovery and retrieval, libraries have implemented new discovery services, such as next generation catalogues, federated search, and Web-scale discovery, in addition to their traditional integrated library systems. These new discovery services greatly improve the user experience by utilizing existing cataloguing records housed within the library system or in combination with metadata from other sources, both in and outside of libraries. However, to maximize the functionality of these discovery services, libraries must reexamine current cataloguing practices and the way libraries control the bibliographic description to better serve the user's needs. This report discusses how new discovery services use the cataloguing records and the challenges that libraries encounter in bibliographic control to work with new discovery services, including the quality of cataloguing records, granular levels of bibliographic description, and integration of user-generated metadata into the cataloguing records. Each of these aspects requires further discussion.

Abstract

This study presents preliminary themes surfaced from an ongoing ethnographic study. The research question is: how and where do cultures influence the cataloging practices of using U.S. standards to catalog Chinese materials? The author applies warrant as a lens for evaluating knowledge representation systems, and extends the application from examining classificatory decisions to cataloging decisions. Semantic warrant as a conceptual tool allows us to recognize and name the various rationales behind cataloging decisions, grants us explanatory power, and the language to "visualize" and reflect on the conflicting priorities in cataloging practices. Through participatory observation, the author recorded the cataloging practices of two Chinese catalogers working on the same cataloging project. One of the catalogers is U.S. trained, and another cataloger is a professor of Library and Information Science from China, who is also a subject expert and a cataloger of Chinese special collections. The study shows how the catalogers describe Chinese special collections using many U.S. cataloging and classification standards but from different approaches. The author presents particular cases derived from the fieldwork, with an emphasis on the many layers presented by cultures, principles, standards, and practices of different scope, each of which may represent conflicting warrants. From this, it is made clear that the conflicts of warrants influence cataloging practice. We may view the conflicting warrants as an interpretation of the tension between different semantic warrants and the globalization and localization of cataloging standards.

Abstract

This case study demonstrates how competitive usability testing informs the selection and purchase of a next-generation catalogue (NGC) or Web-scale discovery system (WSDS) to enhance a current library catalogue. Using competitive usability techniques, the authors explain how different NGCs and WSDSs solve issues that catalogue users may face when searching for materials in the online catalogue. The goal of this study is to provide a framework that identifies concrete evidence in support of purchase recommendations for an effective system that adequately addresses locally identified issues with catalogue searches. The process of selecting live system implementations from peer institutions is outlined. Steps include surveying library staff about their current library catalogue. Survey results and documented reference questions provided the foundation for user tasks created by testers for use in this study. This multifaceted research design resulted in a case study that captures current issues that users encounter in the discovery and access to library materials and shows how to include competitive usability techniques as part of a purchase rationale while assessing how well a variety of next-generation discovery and access systems address users' issues.

Abstract

Außerdem wurden die Pläne, Erwartungen und Befürchtungen der WU-Bibliothek im Zusammenhang mit Primo festgehalten. Aufgrund eines Vergleichs von Informationen aus Experteninterviews sollen anschließend bewährte Vorgehensweisen für andere Institutionen und Verbünde, die den Einsatz der Search & Discovery-Software planen, identifiziert werden. Zu diesem Zweck wurden Bibliothekarinnen und Bibliothekare aus wissenschaftlichen Bibliotheken befragt, die in den Einführungsprozess involviert waren. Dies sind im Speziellen Angestellte der Universitätsbibliothek Mannheim, der Universitäts- und Landesbibliothek Tirol in Innsbruck, der Universitätsbibliothek Wien und der Bibliothek der ETH Zürich, zugleich Host des Schweizer NEBIS-Verbunds. Ergänzend wurde als Primo-Host der österreichischen Bibliotheken die Österreichische Bibliothekenverbund und Service Gesellschaft mbH (OBVSG) kontaktiert. Dabei wurden von den Projektverantwortlichen insbesondere die Erwartungen vor dem Einsatz von Primo erfragt, aber auch mit welchen Hürden und Problemen die Implementierung der Software verbunden war. Ein Vergleich der erhaltenen Informationen erlaubt einen Rückschluss auf generell erhoffte Veränderungen durch die Einführung des Systems und häufig auftretende Ereignisse im Projektverlauf. Verglichen werden dabei nicht nur die Angaben der Primo einsetzenden Bibliotheken untereinander, sondern auch deren Erfahrungen mit den von Ex Libris angenommenen Projektverläufen. Abschließend werden auch noch die Erwartungen der WU-Bibliothek mit den gesammelten Informationen verglichen.
