    Abstract
    This study explored the functionality of the University of Chicago's faceted catalog, Lens, in respect to monographic series. A user study was designed to evaluate the efficiency of Lens in searching for monographic series and also to determine whether controlled series access in the catalog record improves the search results. The results of the study indicate that while Lens could be considered an adequate tool for searching series that are known to be published under the same title, some changes would make it a better search engine for a series that changes series statements from one volume to another.

    Abstract
    This paper presents the first large-scale investigation of the users and uses of WorldCat.org, the world's largest bibliographic database and global union catalog. Using a mixed-methods approach involving focus group interviews with 120 participants, an online survey with 2,918 responses, and an analysis of transaction logs of approximately 15 million sessions from WorldCat.org, the study provides a new understanding of the context for global union catalog use. We find that WorldCat.org is accessed by a diverse population, with the three primary user groups being librarians, students, and academics. Use of the system is found to fall within three broad types of work-task (professional, academic, and leisure), and we also present an emergent taxonomy of search tasks that encompass known-item, unknown-item, and institutional information searches. Our results support the notion that union catalogs are primarily used for known-item searches, although the volume of traffic to WorldCat.org means that unknown-item searches nonetheless represent an estimated 250,000 sessions per month. Search engine referrals account for almost half of all traffic, but although WorldCat.org effectively connects users referred from institutional library catalogs to other libraries holding a sought item, users arriving from a search engine are less likely to connect to a library.

    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
    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
    Das Exzellenzcluster Kognitive Interaktionstechnologie (CITEC) an der Universität Bielefeld beschäftigt sich seit 2013 mit der virtuellen Realität (VR). Ausgehend von konkreten Projektkooperationen (Publikations- und Forschungsdatenmanagement) mit der Universitätsbibliothek ist die Idee entstanden, mit der in 2016 neu angebotenen Konsumer-VR-Hardware die im Labor entwickelten Interaktionstechniken auf geeignete Szenarien im Bereich von bibliothekarischen Umgebungen anzuwenden. Als interessantes Anwendungsgebiet kristallisierte sich im gemeinsamen Diskurs die Literatursuche heraus: Als Suchsystem wurde die Bielefelder BASE-Datenbank (d.i. Bielefeld Academic Search Engine mit inzwischen mehr als 100 Mio. indexierten Dokumenten) ausgewählt. Diese Auswahl erfolgte vor dem Hintergrund, dass sich die von zahlreichen externen Institutionen bereits genutzte API-Schnittstelle als universell und robust erwiesen hat und umfangreiche Funktionen bereitstellt. Auf der Grundlage der umfangreichen theoretischen und praktischen Erfahrungen des CITEC mit VRTechniken wurde der Prototyp für eine virtuelle Suchumgebung realisiert, der ein Retrieval in einem Suchraum von Online-Dokumenten erlaubt. Die Nutzerinnen und Nutzer können die Suchanfrage explorativ zusammenstellen und dabei die Ergebnisse intuitiv verwalten. Unterstützt werden sie dabei durch Ergebnisanzeige, Sortierung, Optimierung des Suchergebnisses mittels Suchverfeinerung (Drilldown-basiert) oder Anfrageerweiterung und Wiederverwendung von abgelegten Ergebnissen. Gleichzeitig wird der Zugriff- und Lizenzstatus visualisiert und die Detailanzeige der Metadaten des Objektes integriert.

    Abstract
    The conflict between librarians' ethics and their responsibilities in the process of progressive collection management, which applies the principles of cost accounting to libraries, to call attention to the "bad books" in their collections that are compromised by age, error, abridgement, expurgation, plagiarism, copyright violation, libel, or fraud, is discussed. According to Charles Cutter, notes in catalog records should call attention to the best books but ignore the bad ones. Libraries that can afford to keep their "bad books," however, which often have a valuable second life, must call attention to their intellectual contexts in notes in the catalog records. Michael Bellesiles's Arming America, the most famous case of academic fraud at the turn of the twenty-first century, is used as a test case. Given the bias of content enhancement that automatically pulls content from the Web into library catalogs, catalog notes for "bad books" may be the only way for librarians to uphold their ethical principles regarding collection management while fulfilling their professional responsibilities to their users in calling attention to their "bad books."

    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
    A bibliographic record is a conceptual whole that includes all bibliographic information about a resource together in one place. With the Semantic Web, individual data statements are linked across the web. This position article argues that the traditional conceptualization of bibliographic records affects the affordances and limitations of that data. A historical analysis of the development of bibliographic records contrasted with the Semantic Web model reveals how the "record" model shaped library cataloging and the implications on library catalogs today. Reification of the record model for bibliographic data hampers possibilities for innovation in cataloging, inspiring a reconceptualization of bibliographic description.

    Abstract
    Libraries are currently seeking to restructure their services and develop new cataloguing standards to position themselves on the web, which has become the main source of information and documents. The current upheaval within the profession is accompanied by the belief that libraries have a major role to play in identifying and supplying content due to their extensive high quality databases, which remain untapped despite efforts to increase catalog performance. They continue to rely on a strategy that has been proven successful since the mid-nineteenth century while seeking other models for their data. Today, they aim to exploit changes brought about by the web to improve content identification. The current intense debate on RDA implementation mirrors this desire for change. The debate is rooted in past efforts and yet tries to incite radical changes as it provides for interoperability from the creation of records through an object modeling in line with web standards and innovations. These innovations are presented through an historical perspective inspired by writings by librarians who are entrusted with helping in the development of bibliographic description standards.

    Abstract
    One of the presumed advantages of next-generation library catalogue interfaces is that the user experience is improved-that it is both richer and more intuitive. Often the interfaces come with little or no user-facing documentation or imbedded "help" for patrons based on an assumption of ease of use and familiarity of the experience, having followed best practices in use on the Web. While there has been much gray literature (published on library Web sites, etc.) interrogating these implicit claims and contrasting the new interfaces to traditional Web-based catalogues, this article details a consistent and formal comparison of whether users can actually accomplish common library tasks, unassisted, using these interfaces. The author has undertaken a task-based usability test of vendor-provided next-generation catalogue interfaces and Web-scale discovery tools (Encore Synergy, Summon, WorldCat Local, Primo Central, EBSCO Discovery Service). Testing was done with undergraduates across all academic disciplines. The resulting qualitative data, noting any demonstrated trouble using the software as well as feedback or suggested improvements that the users may have about the software, will assist academic libraries in making or validating purchase and subscription decisions for these interfaces as well as help vendors make data-driven decisions about interface and experience enhancements.

    Abstract
    Subject searching is difficult with traditional text-based online public access library catalogues (OPACs), and the next-generation discovery layers are keyword searching and result filtering tools that offer little support for subject browsing. Next-generation OPACs ignore the rich network of relations offered by controlled subject vocabulary, which can facilitate subject browsing. A new generation of OPACs could leverage existing information-organization investments and offer online searchers a novel browsing and searching environment. This is a case study of the design and development of a virtual reality subject browsing and information retrieval tool. The functional prototype shows that the Library of Congress subject headings (LCSH) can be shaped into a useful and usable tree structure serving as a visual metaphor that contains a real world collection from the domain of science and engineering. Formative tests show that users can effectively browse the LCSH tree and carve it up based on their keyword search queries. This study uses a complex information-organization structure as a defining characteristic of an OPAC that goes beyond the standard keyword search model, toward the cutting edge of online search tools.

    Abstract
    Is there a future for the library cataloger? For the past thirty years this debate has increased with the continued growth of online resources and greater access to the World Wide Web. Many are concerned that library administrators believe budgetary resources would be better spent on other matters, leaving library users with an overabundance of electronic information to muddle through on their own. This article focuses on the future of the cataloging profession and its importance to the needs of library patrons.

    Abstract
    Vor 20 Jahren, genau gesagt am 26. Juli 1996, erblickte die Literatursuchmaschine "KVK" das Licht der Internet-Welt. Seit damals wurden mehrere Milliarden Suchanfragen von Karlsruhe aus an andere Web-Kataloge von Bibliotheken und Verbünden geschickt, Trefferlisten ausgewertet und den Nutzern in einheitlicher Form präsentiert. Dieser Beitrag erklärt, warum der KVK entwickelt wurde und warum es diesen "Internet-Dino" auch heute noch gibt und beschreibt den aktuellen Stand.

    Abstract
    This paper explores a technique to improve searcher access to library collections by providing a faceted search interface built on a data model based on the Functional Requirements for Bibliographic Records (FRBR). The prototype provides a Workcentric view of a moving image collection that is integrated with bibliographic and holdings data. Two sets of facets address important user needs: "what do you want?" and "how/where do you want it?" enabling patrons to narrow, broaden and pivot across facet values instead of limiting them to the tree-structured hierarchy common with existing FRBR applications. The data model illustrates how FRBR is being adapted and applied beyond the traditional library catalog.

    Abstract
    Although academic libraries are increasingly converting stacks into collaborative spaces and physical books and journals are being replaced by their electronic counterparts, the concept of browsing as a means of discovery is seeing a resurgence in the world of search and discovery. While many users start their online research with electronic databases and library catalogues, interviews with North Carolina State University Libraries patrons provide evidence that physically browsing the shelves to find similar materials is still common. A growing awareness of the need to preserve this type of serendipitous discovery as a complement to keyword searching is inspiring the development of online virtual browsing tools that replace and enhance physical access to library stacks.

    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
    Next-generation catalogues are providing opportunities for library professionals and users to interact, collaborate, and enhance core library functions. Technology, innovation, and creativity are all components that are merging to create a localized, online social space that brings our physical library services and experiences into an online environment. While patrons are comfortable creating user-generated information on commercial Web sites and social media Web sites, library professionals should be exploring alternative methods of use for these tools within the library setting. Can the library catalogue promote remote readers' advisory services and act as a localized "Google"? Will patrons or library professionals be the driving force behind user-generated content within our catalogues? How can cataloguers be sure that the integrity of their bibliographic records is protected while inviting additional data sources to display in our catalogues? As library catalogues bring our physical library services into the online environment, catalogues also begin to encroach or "mash-up" with other areas of librarianship that have not been part of a cataloguer's expertise. Using library catalogues beyond their traditional role as tools for discovery and access raises issues surrounding the expertise of library professionals and the benefits of collaboration between frontline and backroom staff.

    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.
