- 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
- This paper examines the need for increased subject catalog access to imaginative literature, focusing on the environment of the academic/research library. New trends in scholarship have created more need for such subject access. We can develop a basis for subject access to imaginative literature by examining the historical treatment of imaginative literature and by drawing upon the past and present work of librarians, other information professionals such as indexers, and literary scholars. While many information professionals have recognized a need for increased subject access to individual works of imagination, there has been no clear consensus on how to do this. This paper represents a step forward in that direction, showing how we might use LCSH to express the themes or topics of an imaginative work. It is important that such subject access be multi-dimensional, identifying both concrete and abstract levels of meaning. Using The Scarlet Letter by Nathaniel Hawthorne as an example, it is demonstrated how LC-type subject headings using LC subject terms with genre/form subdivisions can be developed.

- Abstract
- Purpose - The purpose of this paper is to explore the information needs of one user group, public library fiction readers, in order to reveal a design of an online community at the local level. Examination of user-generated metadata can reveal new approaches to information architecture. Design/methodology/approach - A literature review into behaviors of virtual communities; surveying public library readers regarding search behavior characteristics - the survey included a sample "tagging" exercise to determine whether public library communities could create meaningful metadata for retrieval purposes. Findings - The use of relevance as an indicator of tag quality is flawed: in a survey, public library readers "tagged" the novel The Da Vinci Code. The resulting collection of tags provided a richer description of the book than did the social book-related web site www.librarything.com. Tag collections can be broken down into different categories, each reflecting a different "facet" of the novel: character, plot, subject/topic, setting, and genre. Faceted structure to tags enables users to choose the context of the tag to the novel. Research limitations/implications - This research is relevant in the world of social networking sites, online communities, or any other such system where users generate descriptive metadata. Examination of such metadata can reveal facets, which can guide the architect/librarian in the design of a versatile architecture. Originality/value - This research resulted in a manifold design for a public-library-based online community that allowed for the full expression of users' information needs. This research introduces a faceted structure to current approaches for user-generated metadata, adding versatility to search terms.

- Abstract
- In der globalen Online-Umgebung stellen viele bibliographische Dienstleistungen integrierten Zugang zu unterschiedlichen internetbasierten OPACs zur Verfügung. In solch einer Umgebung erwarten Benutzer mehr Übereinstimmungen innerhalb und zwischen den Systemen zu sehen. Zweck dieser Studie ist, die Indexierungskonsistenz zwischen Systemen zu untersuchen. Währenddessen werden einige Faktoren, die die Indexierungskonsistenz beeinflussen können, untersucht. Wichtigstes Ziel dieser Studie ist, die Gründe für die Inkonsistenzen herauszufinden, damit sinnvolle Vorschläge gemacht werden können, um die Indexierungskonsistenz zu verbessern. Eine Auswahl von 3307 Monographien wurde aus zwei chinesischen bibliographischen Katalogen gewählt. Nach Hooper's Formel war die durchschnittliche Indexierungskonsistenz für Indexterme 64,2% und für Klassennummern 61,6%. Nach Rolling's Formel war sie für Indexterme 70,7% und für Klassennummern 63,4%. Mehrere Faktoren, die die Indexierungskonsistenz beeinflussen, wurden untersucht: (1) Indexierungsbereite; (2) Indexierungsspezifizität; (3) Länge der Monographien; (4) Kategorie der Indexierungssprache; (5) Sachgebiet der Monographien; (6) Entwicklung von Disziplinen; (7) Struktur des Thesaurus oder der Klassifikation; (8) Erscheinungsjahr. Gründe für die Inkonsistenzen wurden ebenfalls analysiert. Die Analyse ergab: (1) den Indexieren mangelt es an Fachwissen, Vertrautheit mit den Indexierungssprachen und den Indexierungsregeln, so dass viele Inkonsistenzen verursacht wurden; (2) der Mangel an vereinheitlichten oder präzisen Regeln brachte ebenfalls Inkonsistenzen hervor; (3) verzögerte Überarbeitungen der Indexierungssprachen, Mangel an terminologischer Kontrolle, zu wenige Erläuterungen und "siehe auch" Referenzen, sowie die hohe semantische Freiheit bei der Auswahl von Deskriptoren oder Klassen, verursachten Inkonsistenzen.

- Abstract
- Rare book cataloguers have on various occasions expressed frustration that their carefully constructed rare book records 'disappear' into 'vanilla' catalogues designed and maintained by system vendors or by local system staff with only the most general knowledge of cataloguing. Reports the results of a 1993 survey of online systems used for rare book cataloguing and takes a first step toward making a set of recommendations regarding the display and indexing of rare book records in such systems

- Abstract
- For the purposes of library and information science research, transaction lof analysis can be narrowly defined as the study of electronically recorded interactions between online information retrieval systems and the persons who search for the information found in those systems. Researchers most often use transaction log data with the intention of improving an information retrieval system, human utilization of the system, and human (and perhaps also system) understanding of how the system is used by information seekers. Transaction log analysis can provide system designers and managers with valuable information about how the system is being employed by actual users. It also can be used to study prototype systems or potential system improvements

- Abstract
- In Northern Germany, the State of Lower Saxony has developed an online library network, the center of which is the Library Computer Center at the State and University Library in Goettingen. This center offers the following data bases online: the union catalogue of serials in Lower Saxony libraries; the union catalogue of books since 1977 in these libraries; the IBZ and IBR; the last two years of the Deutsche Bibliographie, the British National Bibliography and, within the next few months, the titles offered by the Library of Congress (all in full service); then all new titles in this data base will be compatible to MARC II.

- Abstract
- The article is a researcher's eye view of the value of the library catalog not only as a database to be searched for surrogates of objects of study, but as a corpus of text that can be analyzed in its own right, or incorporated within the researcher's own research database. Barriers are identified in the ways in which catalog data can be output and the technical skills researchers currently need to download, ingest, and manipulate data. Research tools and datasets created by, or in collaboration with, the library community are identified.

- 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
- 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."
