- Abstract
- Popular commercial on-line services such as Google, e-Bay, Amazon, and Netflix have evolved quickly over the last decade to help people find what they want, developing information retrieval strategies such as usefully ranked results, spelling correction, and recommender systems. Online library catalogs (OPACs), in contrast, have changed little and are notoriously difficult for patrons to use (University of California Libraries, 2005). Over the past year (June 2005 to the present), the Melvyl Recommender Project (California Digital Library, 2005) has been exploring methods and feasibility of closing the gap between features that library patrons want and have come to expect from information retrieval systems and what libraries are currently equipped to deliver. The project team conducted exploratory work in five topic areas: relevance ranking, auto-correction, use of a text-based discovery system, user interface strategies, and recommending. This article focuses specifically on the recommending portion of the project and potential extensions to that work.

- Abstract
- The starting-point of the paper is the debate recently developed in LIS literature about OPAC enhancement and the necessity to design OPACs based on search engines features. Supposed improving tools as relevance ranking and relevance feedback devices are examinated. Possible OPAC development lines, based on theoretical examination of relevance and pertinence concepts, according to Sarácevic view, and following semantics perspectives, are presented. Finally, enhancement of OPACs starting from their inner characteristics is proposed, and a plan to improve semantic search functions while maintaining existing indexing methodologies, that is document conceptual analysis, is outlined.

- Abstract
- According to the Calhoun report, library operations that are not digital, that do not result in resources that are remotely accessible, that involve professional human judgement or expertise, or that require conceptual categorization and standardization rather than relevance ranking of keywords, do not fit into its proposed "leadership" strategy. This strategy itself, however, is based on an inappropriate business model - and a misrepresentation of that business model to begin with. The Calhoun report draws unjustified conclusions about the digital age, inflates wishful thinking, fails to make critical distinctions, and disregards (as well as mischaracterizes) an alternative "niche" strategy for research libraries, to promote scholarship (rather than increase "market position"). Its recommendations to eliminate Library of Congress Subject Headings, and to use "fast turnaround" time as the "gold standard" in cataloging, are particularly unjustified, and would have serious negative consequences for the capacity of research libraries to promote scholarly research.

- Abstract
- An increasing number of library user studies are employing ethnographic techniques as an alternative to more traditional qualitative methods such as surveys. Such techniques, however, are only beginning to see significant application to catalog user studies. Beginning with a discussion of the applied ethnographic method and its current usage within the field of Library and Information Science research, this article will assess methods that have traditionally been applied to studies of catalog users and present the case for the potential of an ethnographic approach for future catalog evaluation and design.

- Abstract
- Contends that library catalogues need to be seen as merely part of the information seeker's world and proposes the concept of a learning catalogue for library clients which will capture ways in which clients use data thus providing ideas for the further development of the system. Proposes a client centred system which is separated to maintain the bibliographic database from the mode of presentation of that data to the client. The designer of retrieval systems, by accepting that each client brings a unique view of the world's knowledge base to the information seeking activity, needs to acknowledge that this view of the world must be handled uniquely. By overlaying the idea of a learning component, it is possible to see how future queries might be handled more efficiently and the system can grow with client's developing needs

- Abstract
- This article first compares and contrasts the essential, fundamental differences between traditional and digital information mediums. It then reexamines the role of the online public access catalog (OPAC), refines the definition of library's catalog, and advocates the addition of Internet resources within the OPAC. Next, the article describes the building of the Alex Catalog, a catalog of Internet resources in the in the form of MARC records. Finally, this article outlines a process of integrating the futher inclusion of other Internet resources into OPACs as well as some of the obstacles such a process manifests.

- Abstract
- Die Überführung der konventionellen Zettelkataloge in weltweit frei zugängliche Online-Kataloge zählt zu den größten Errungenschaften der Bibliotheksautomatisierung. Seit den ersten Implementierungen in den siebziger Jahren des letzten Jahrhunderts wurden die Programmfunktionen der "elektronischen Zettelkästen" stetig ausgebaut. Heutige Kataloge bilden den Kern integrierter Bibliothekssysteme, die sowohl die innerbetrieblichen als auch die geschäftsübergreifenden Prozesse unterstützen - angefangen von der Erwerbung über die Katalogisierung bis hin zur Ausleihe von Medien. Die Entwicklung der Bibliothekssysteme orientierte sich lange Zeit ausschließlich an bibliothekarischen Anforderungen. Die Bedürfnisse der Nutzer fanden kaum Berücksichtigung oder wurden in einigen Bereichen gänzlich außer Acht gelassen. Es ist daher nicht verwunderlich, dass ein Großteil der heutigen Benutzer Internet-Suchmaschinen als Einstieg für ihre Literaturrecherche verwendet. Internet-Suchmaschinen haben in den letzten zehn Jahren den Prozess der Informationsrecherche revolutioniert. Bekanntestes Beispiel ist der Weltmarktführer Google, der in Deutschland knapp 90 Prozent der an Suchmaschinen gerichteten Anfragen beantwortet. Der große Erfolg von Google gründet sich im Wesentlichen auf vier Faktoren: leichte Bedienbarkeit, Schnelligkeit der Suche, Größe des Indexvolumens und relevanzbezogene Ranking-Algorithmen. Insbesondere die von Internet-Suchmaschinen standardmäßig vorgenommene Sortierung der Treffer nach Relevanz hat das Suchverhalten der Nutzer nachhaltig beeinflusst. So zeigen verschiedene Studien, dass die Benutzer in der Regel nur zwei bis drei Begriffe in das einzeilige Suchformular eingeben und sich dann anschließend auf die Treffer beschränken, die ohne Scrollen zu erreichen sind. Durchschnittlich werden daher pro Recherche lediglich fünf Treffer angeklickt und gesichtet. Der gesamte Vorgang dauert nur etwa 15 Sekunden. Wird das Gesuchte in dieser Zeit nicht gefunden, wird die Suche abgebrochen oder modifiziert. Das bei den Suchmaschinen zur Gewohnheit gewordene Suchverhalten wird von den Nutzern zunehmend auch auf andere Recherchesysteme übertragen. Bibliotheken und Softwarehersteller von Bibliothekssystemen haben diesen Trend erkannt und in den letzten Jahren verstärkt damit begonnen, ihre Suchsysteme an die geänderten Nutzungsgewohnheiten der Endanwender anzupassen.

- Abstract
- The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.

- Abstract
- This think piece tells why the online library catalog fell from grace and why new directions pertaining to cataloging simplification and primary sources will not attract people back to the online catalog. It proposes an alternative direction that has greater likelihood of regaining the online catalog's lofty status and longtime users. Such a direction will require paradigm shifts in library cataloging and in the design and development of online library catalogs that heed catalog users' longtime demands for improvements to the searching experience. Our failure to respond accordingly may permanently exile scholarly and scientific information to a netherworld where no one searches while less reliable, accurate, and objective sources of information thrive in a paradise where people prefer to search for information.
The impetus for this essay is the library community's uncertainty regarding the present and future direction of the library catalog in the era of Google and mass digitization projects. The uncertainty is evident at the highest levels. Deanna Marcum, Associate Librarian for Library Services at the Library of Congress (LC), is struck by undergraduate students who favor digital resources over the online library catalog because such resources are available at anytime and from anywhere (Marcum, 2006). She suggests that "the detailed attention that we have been paying to descriptive cataloging may no longer be justified ... retooled catalogers could give more time to authority control, subject analysis, [and] resource identification and evaluation" (Marcum, 2006, 8). In an abrupt about-face, LC terminated series added entries in cataloging records, one of the few subject-rich fields in such records (Cataloging Policy and Support Office, 2006). Mann (2006b) and Schniderman (2006) cite evidence of LC's prevailing viewpoint in favor of simplifying cataloging at the expense of subject cataloging. LC commissioned Karen Calhoun (2006) to prepare a report on "revitalizing" the online library catalog. Calhoun's directive is clear: divert resources from cataloging mass-produced formats (e.g., books) to cataloging the unique primary sources (e.g., archives, special collections, teaching objects, research by-products). She sums up her rationale for such a directive, "The existing local catalog's market position has eroded to the point where there is real concern for its ability to weather the competition for information seekers' attention" (p. 10). At the University of California Libraries (2005), a task force's recommendations parallel those in Calhoun report especially regarding the elimination of subject headings in favor of automatically generated metadata. Contemplating these events prompted me to revisit the glorious past of the online library catalog. For a decade and a half beginning in the early 1980s, the online library catalog was the jewel in the crown when people eagerly queued at its terminals to find information written by the world's experts. I despair how eagerly people now embrace Google because of the suspect provenance of the information Google retrieves. Long ago, we could have added more value to the online library catalog but the only thing we changed was the catalog's medium. Our failure to act back then cost the online catalog the crown. Now that the era of mass digitization has begun, we have a second chance at redesigning the online library catalog, getting it right, coaxing back old users, and attracting new ones. Let's revisit the past, reconsidering missed opportunities, reassessing their merits, combining them with new directions, making bold decisions and acting decisively on them.

- Abstract
- Auf dem Hintergrund der aktuellen OPAC-Entwicklung in Deutschland werden im ersten Teil einzelne Aspekte des OPAC-Designs kommentiert. Es wird u.a. auch auf Möglichkeiten einer Standardisierung der Schnittstelle Retrieval-Software / Benutzeroberfläche eingegangen. Die derzeit dominierenden Online-Kataloge sind für eine Massenbenutzung nur bedingt geeignet, da sie in hohem Maße fehlerintolerant sind, eine Analyse nach Suchfeldern verlangen und mit grundsätzlichen Mängeln der Boole'schen Suchlogik behaftet sind. Im zweiten Teil werden werden Alternativen diskutiert, zum einen in Form eines alphabetisch sortierten Online-Katalogs, zum anderen in Form intelligenter bibliographischer Auskunftssysteme, die Ähnlichkeitssuchen bzw. sog. 'Closest-Match-Suchen' gestatten. Hierzu werden verschiedene Konzepte und Vorschläge vorgestellt

- 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 quality of large catalogs is uneven and often low, but this issue is underrated and understudied. Library catalogs often fail to communicate correct and clear information to users and their low quality is not simply due to faults, duplications, and so on but also to unwise cataloging standards and policies. While there is plenty of uncontrolled information about books and other publications, the need for good-quality bibliographic information is apparent and library catalogs may provide a trustworthy map of the publishing output, with full control of editions, works, authors, and so on and effective navigation functions, which are lacking in today's information-rich environment.
