    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 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.

    Rez. in: ABI-Technik 21(2002) H.3, S.292 (E. Pietzsch): "Otto C. Oberhauser hat mit seiner Diplomarbeit eine beeindruckende Analyse digitalisierter Zettelkataloge (CIPACs) vorgelegt. Die Arbeit wartet mit einer Fülle von Daten und Statistiken auf, wie sie bislang nicht vorgelegen haben. BibliothekarInnen, die sich mit der Digitalisierung von Katalogen tragen, finden darin eine einzigartige Vorlage zur Entscheidungsfindung. Nach einem einführenden Kapitel bringt Oberhauser zunächst einen Überblick über eine Auswahl weltweit verfügbarer CIPACs, deren Indexierungsmethode (Binäre Suche, partielle Indexierung, Suche in OCR-Daten) und stellt vergleichende Betrachtungen über geographische Verteilung, Größe, Software, Navigation und andere Eigenschaften an. Anschließend beschreibt und analysiert er Implementierungsprobleme, beginnend bei Gründen, die zur Digitalisierung führen können: Kosten, Umsetzungsdauer, Zugriffsverbesserung, Stellplatzersparnis. Er fährt fort mit technischen Aspekten wie Scannen und Qualitätskontrolle, Image Standards, OCR, manueller Nacharbeit, Servertechnologie. Dabei geht er auch auf die eher hinderlichen Eigenschaften älterer Kataloge ein sowie auf die Präsentation im Web und die Anbindung an vorhandene Opacs. Einem wichtigen Aspekt, nämlich der Beurteilung durch die wichtigste Zielgruppe, die BibliotheksbenutzerInnen, hat Oberhauser eine eigene Feldforschung gewidmet, deren Ergebnisse er im letzten Kapitel eingehend analysiert. Anhänge über die Art der Datenerhebung und Einzelbeschreibung vieler Kataloge runden die Arbeit ab. Insgesamt kann ich die Arbeit nur als die eindrucksvollste Sammlung von Daten, Statistiken und Analysen zum Thema CIPACs bezeichnen, die mir bislang begegnet ist. Auf einen schön herausgearbeiteten Einzelaspekt, nämlich die weitgehende Zersplitterung bei den eingesetzten Softwaresystemen, will ich besonders eingehen: Derzeit können wir grob zwischen Komplettlösungen (eine beauftragte Firma führt als Generalunternehmung sämtliche Aufgaben von der Digitalisierung bis zur Ablieferung der fertigen Anwendung aus) und geteilten Lösungen (die Digitalisierung wird getrennt von der Indexierung und der Softwareerstellung vergeben bzw. im eigenen Hause vorgenommen) unterscheiden. Letztere setzen ein Projektmanagement im Hause voraus. Gerade die Softwareerstellung im eigenen Haus aber kann zu Lösungen führen, die kommerziellen Angeboten keineswegs nachstehen. Schade ist nur, daß die vielfältigen Eigenentwicklungen bislang noch nicht zu Initiativen geführt haben, die, ähnlich wie bei Public Domain Software, eine "optimale", kostengünstige und weithin akzeptierte Softwarelösung zum Ziel haben. Einige kritische Anmerkungen sollen dennoch nicht unerwähnt bleiben. Beispielsweise fehlt eine Differenzierung zwischen "Reiterkarten"-Systemen, d.h. solchen mit Indexierung jeder 20. oder 50. Karte, und Systemen mit vollständiger Indexierung sämtlicher Kartenköpfe, führt doch diese weitreichende Designentscheidung zu erheblichen Kostenverschiebungen zwischen Katalogerstellung und späterer Benutzung. Auch bei den statistischen Auswertungen der Feldforschung hätte ich mir eine feinere Differenzierung nach Typ des CIPAC oder nach Bibliothek gewünscht. So haben beispielsweise mehr als die Hälfte der befragten BenutzerInnen angegeben, die Bedienung des CIPAC sei zunächst schwer verständlich oder seine Benutzung sei zeitaufwendig gewesen. Offen beibt jedoch, ob es Unterschiede zwischen den verschiedenen Realisierungstypen gibt.
