    Abstract
    This paper surveys card-image public access catalogues (CIPACs) - online library catalogues based an databases of digitised catalogue cards and more or less sophisticated mechanisms for browsing or searching. Solutions of this kind have been implemented by a number of libraries in various countries since the mid-1990s, mainly as inexpensive altematives to a full retrospective conversion of their old catalogues. The article presents a Web page dedicated to CIPACs, identifies and describes four main categories of interface software for such catalogues, and provides a comparative overview of 50 CIPACs in 11 countries, looking at aspects such as geographical distribution, growth and size, software, number of catalogues, processing and index creation, navigation, image formats, and other features.

    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.
    Nun haben Diplomarbeiten einen eigenen Charakter. Ihre Zielsetzung ist nicht unbedingt, Handlungsleitfäden zu geben. Manche FachkollegInnen, die schon selbst mit der Digitalisierung von Katalogen zu tun hatten, fragen sich aber, ob die jeweils gefundene Lösung denn tatsächlich die "beste" erreichbare war, ob es sich lohnt, über Verbesserungen nachzudenken, wie ihre Lösung im Vergleich zu anderen steht, ob die eingesetzte Recherchesoftware gute Ergebnisse liefert, ob die zunächst vielleicht niedrigen Erstellungskosten nicht doch relativ lange Verweildauern, d.h. verdeckte Kosten, bei der Recherche zur Folge haben. Oberhauser gibt dazu lediglich am Rande einige Hinweise. Wünschenswert wäre, wenn derartige Detailuntersuchungen in weiteren Arbeiten vorgenommen würden."

    Abstract
    This article identifies and discusses the issues and problems that need to be considered in the process of planning and implementing card-image public access catalogues (CIPACs). CIPACs are online library catalogues based an databases of digitised catalogue cards with more or less sophisticated mechanisms for browsing or searching. Solutions of this kind have been implemented by a number of libraries in various countries since the mid-1990s, mainly as inexpensive alternatives to full retrospective conversion of their old catalogues. Based upon a questionnaire and relevant literature, the article looks at the following aspects: cost, conversion Speed, universal access, saving of space, preservational aspects, Software selection, preparing the card catalogue for conversion, scanning and quality control, image standards, optical character recognition, manual and intellectual input, technological aspects, administrative tools, organisational aspects, peculiarities of old catalogues, presentation of CIPACs to the users, and life expectancy of card-image catalogues.

    Abstract
    Existing Online Public Access Catalogues (OPACs) demonstrate differences in the range and complexity of their functional features, terminology, and help facilities. Many libraries already have OPACs and many of them have a need for guidelines that help them to design or redesign the displays for their OPACs, taking their users' needs into account. This book provides such guidelines, recommendations and a corpus of good practice to assist libraries in this process. The audience for these guidelines is librarians charged with customising OPAC software and vendors and producers of this software. The guidelines are mainly designed for general libraries with collections of resources in the humanities, the social sciences, and the pure and applied sciences. They are intended to apply to any type of catalogue, independently of the kind of interface and technology used. This is the Final Report of a Task Force an the matter, which was approved by the Standing Committee of the IFLA Cataloguing Section.

    Abstract
    Purpose - The objective of this study is to establish the opinion of users with respect to the awareness and utilisation of, as well as their satisfaction level with, the use of the online public access catalogue (OPAC). Design/methodology/approach - The paper deals with the applicability and utility of OPACs in five libraries in New Delhi, namely the Indian Institute of Technology; Jawaharlal Nehru University Library; Dr Zakir Husain Library, Jamia Millia Islamia; National Information System for Communication and Information Resources (NISCAIR); and the Defence Science Information and Documentation Centre (DESIDOC). A questionnaire was developed and distributed randomly to 128 users including undergraduates and post graduate students as well as MPhil. and PhD scholars. Users returned 115 completed questionnaires of which 100 were selected for analysis. Findings - The paper finds that the OPAC system has changed the traditional concept of access to library resources. It allows simple as well as complex searches. Document access is still one of the most important approaches of users to visit the library, and a study of the effectiveness of an OPAC is useful in this respect. Regarding results, sometimes users face problems of recall and precision. However, in some searches users are not able to find relevant documents on account of various factors. Data show that a high percentage of respondents are utilising the OPAC as a search tool for retrieving documents. Also, most of the users handle the OPAC themselves. Significantly, the satisfaction level of users was high with the OPAC facilities. Nevertheless, not many users are aware of the expert searches provided by OPAC. Originality/value - The paper focuses on many aspects of OPACs, particularly those in India. Librarians, especially those from developing nations, may choose their library automation software packages keeping in view the user's expectation with respect to OPACs.

    Abstract
    »Sacherschließung - können wir uns die noch leisten?« Angesichts des zunehmend geringeren Gesamtetats, der den Bibliotheken zur Verfügung steht, drängt sich diese Frage nahezu auf. Sacherschließung ist teuer und für das moderne Bibliothekswesen nur dann noch tragbar, wenn der Mitteleinsatz in einem angemessenen Verhältnis zum Ergebnis steht, das sich in der Leistungsfähigkeit des Produkts widerspiegelt. Im deutschsprachigen Raum trägt die SWD wesentlich zu einer effektiveren Sacherschließungsarbeit bei. Ihre Pflege und Weiterentwicklung ist jedoch mit einem enormen Aufwand gekoppelt, der nur mit einer entsprechenden Nutzung der Daten für das thematische Retrieval in den OPACs gerechtfertigt werden kann.

    Abstract
    Für die Retrokonversion des nach allgemeiner Einschätzung wichtigsten Katalogbestandes in Bayern, der noch nicht online verfügbar ist - des Quartkatalogs der Bayerischen Staatsbibliothek (BSB) -, sollte die Zeit des Systemwechsels vom noch großrechnerbasierten BVB-KAT auf ein neues Bibliothekssystem genutzt werden.
    Content
    "Angesichts des Alters (18401952), der Menge (2,3 Millionen Katalogblätter im Quartformat, daher der Name Quartkatalog) und der Schwierigkeit der Vorlagen (über neunzig Prozent handschriftlich) bot es sich für die BSB an, längere Zeit zu prüfen, welches Retrokonversionsverfahren für das geplante Vorhaben am besten geeignet ist unter besonderer Berücksichtigung von Projektdauer, Kosten und unverzichtbarer hoher Qualität der bei der Retrokonversion erstellten Titeldaten. Sorgfältige Vorarbeiten hatten ein Verhältnis von 65 Prozent Zutragungen zu vorhandenen BVB Titeldatensätzen und 35 Prozent Neuaufnahmen prognostiziert. Als entscheidend für den Konversionserfolg wurde daher eine sehr hohe Genauigkeit bei der Entscheidung Neuaufnahme/ Zutragung angesehen, eine hohe Nachvollziehbarkeit der Rechercheentscheidungen sowie die Vermeidung von Dubletten in der Verbunddatenbank. Vor diesem Hintergrund fiel die Entscheidung zu einem Retrokonversionsverfahren unter Ausspeicherung der vorhandenen BVB-Daten, darunter die von der Deutschen Bücherei Leipzig und der Staatsbibliothek Preußischer Kulturbesitz übernommenen Altdaten, mit besonderem Fokus auf die Qualitätssicherung durch den auszuwählenden Dienstleister. In einer europaweiten Ausschreibung wurde im Oktober 2002 der Anbieter Satz-Rechen-Zentrum (SRZ Berlin) ausgewählt, der in den Jahren 1996-1997 bereits die Retrokonversion des IFK der BSB (2,2 Millionen Karten im internationalen Format) erfolgreich bewältigt hatte. Von Dezember 2002 bis Juli 2003 wurden die Katalogschränke sukzessive nach Berlin transportiert, um an zwei für diesen Zweck speziell gebauten Durchzugsscannern 2,3 Millionen Quartblätter mit Vorder- und Rückseite in 256 Graustufen zu digitalisieren. Die insgesamt 4,6 Millionen Bilder (images) umfassen ein Datenvolumen von 221 GByte."
