Abstract

Im vergangenen Herbst hat die Stadt- und Regionalbibliothek Frankfurt an der Oder ihren dritten Medientag veranstaltet - erstmals in Kooperation mit dem Verein deutscher Bibliothekare Berlin-Brandenburg, um so vor allem Fachkollegen zu erreichen. Im Mittelpunkt standen neue Techniken und web-Angebote für Bibliotheken.

Abstract

Die Webseite The International CIPAC List besteht seit 2001. Sie verzeichnet "card-image public access catalogues" (CIPACs), d.h. Online-Kataloge auf der Basis digitalisierter (gescannter) Zettel- bzw. Bandkataloge. Das erste bekannte Beispiel eines solchen Katalogs war der 1994 realisierte Electronic Card Catalog der Universitätsbibliothek Princeton, NJ (USA). Seit der Mitte der 1990er Jahre begannen sich CIPACs auch in Europa zu etablieren. Das zunächst als Nebenprodukt meiner Master-Arbeit (MSc in Information& Library Management, University of Central England, Birmingham, 2002) erstellte Webverzeichnis aller bekannten Kataloge dieser Art begann mit etwa 20 Links. Anfang 2002 waren es bereits 50 Kataloge aus 11 Ländern, Anfang 2007 gar schon 110 Kataloge aus 19 Ländern. Auf den ersten Blick verzeichnet Deutschland mit 37 Links das stärkste Kontingent, doch bei genauerer Betrachtung hält Italien die Spitze, da eine der acht aus diesem Land angeführten Web-Adressen zu der Seite Cataloghi Storici führt, die ihrerseits 215 Kataloge von 35 italienischen Bibliotheken nachweist. Da die Auflistung von über hundert Links den Rahmen einer simplen Webseite, die nur Scroll- und Ankerfunktionen aufwies, sprengte, wurde das Verzeichnis kürzlich in eine neue Form gebracht, in der pro angezeigter Seite immer nur die Kataloge jeweils eines zuvor selektierten Landes angezeigt werden. Dadurch wird das Scrollen weitgehend vermieden; lediglich die Auflistung für Deutschland ist nun länger als eine Bildschirmseite. Wie man mittels einer Google-Recherche unschwer feststellen kann, ist das Verzeichnis inzwischen auf zahllosen Webseiten verlinkt und somit zu einem Service geworden, das weiterhin gepflegt und gewartet werden will. Hinweise auf neue bzw. noch nicht in dieser internationalen Liste verzeichnete CIPACs sind daher stets willkommen (bitte E-Mail an <oberh@web.de>).

Abstract

Obwohl CIPACs bislang keine weitverbreitete "Spezies" von Katalogen darstellen, hat ihre Zahl in den letzten Jahren deutlich zugenommen. Nach einem etwas zögerlichen Start in der ersten Hälfte der 1990er jahre begann das eigentliche "take-off` erst mit 1999; über 80 Prozent aller CIPACS wurden seit damals installiert. Zur Zeit (Februar 2004) weist meine Web-Seite The International CipAC List Links zu 82 Card-Image Katalogen in 15 Staaten auf; ein weiteres Wachstum kann sicherlich erwartet werden. Obwohl mehr als die Hälfte aller CIPACS in deutschsprachigen Ländern realisiert wurde, nimmt die Verbreitung dieses Katalogtyps in anderen Staaten zu. Besonders häufig sind CIPACs auch in der Tschechischen Republik zu finden.

Abstract

Unter der Bezeichnung "CardImage OnlineKataloge" werden im folgenden jene auf den ersten Blick oft seltsam oder gar anachronistisch anmutenden, aber seit einigen Jahren immer häufiger anzutreffenden OPAC Varianten zusammengefasst, die auf einer meist größeren Menge eingescannter (digitalisierter) Katalogzettel und einem mehr oder weniger komfortablen und leistungsfähigen Blätter oder SuchMechanismus basieren. OPACs dieser Art werden auch als "elektronische Zettelkataloge", "digitalisierte Kartenkataloge" oder oft, wenn auch unpräzise, schlicht als "ImageKataloge" bezeichnet. Im Englischen hat sich bislang kein Standardterminus durchgesetzt; in Analogie zu "OPAC" wurde kürzlich das Akronym "CIPAC" (CardImage Public Access Catalogue) vorgeschlagen CIPACS werden in aller Regel als Alternativen zur Retrokonversion im herkömmlichen Sinn (Retrokatalogisierung) eingesetzt, sowohl als Interims als auch als Dauerlösungen. Wie erst jüngst wieder eindrucksvoll vorgerechnet wurde, können dadurch Zeit und vor allem finanzielle Mittel in beträchtlichem Ausmaß eingespart werden; oft handelt es sich für die betreffenden Bibliotheken um die einzige realisierbare Konversionsmöglichkeit. Obwohl der erste große CardImage OnlineKatalog 1994 in den USA in Betrieb genommen wurde, haben seitdem fast ausschließlich Bibliotheken in Kontinentaleuropa (Deutschland, Österreich, Schweiz, Tschechische Republik) derartige CIPACs realisiert. Bekannte Beispiele, die auch das Leistungsspektrum und die Variationsbreite dieses Katalogtyps widerspiegeln, sind etwa die Anwendungen der Österreichischen Nationalbibliothek (ÖNB), verschiedener großer deutscher Bibliotheken sowie der Zentralbibliothek Zürich. Eine vom Autor erstellte Web-Seite verzeichnet alle bisher bekannt gewordenen Kataloge dieser Art

Abstract

Stanford University's Socrates II and University of California at Berkeley's Pathfinder are 2 USA World Wide Web based online publication access catalogues under development. They differ in their design language (how an interface functionally and visually communicates to the users). Evaluates each system's interface design and their ability to communicate functionality to users: analyzes design in terms of: colour, buttons, metaphors, layout, and basic and advanced search modes. Concludes that the design languages of both systems have the right directive and have the potential to evolve

Abstract

Aus Benutzersicht verkörpern Online-Kataloge "the most visible form of library automation." Entweder über das lokale Netzwerk innerhalb der Bibliothek oder eingebunden in das Web-Portal von außerhalb zugänglich, bildet der Online-Katalog den zentralen Ausgangspunkt für die Recherche in Bibliotheksbeständen. Er ist zugleich Kernbestandteil eines integrierten Bibliothekssystems, dessen Entwicklung "has been one of movement from centralized systems, designed and controlled by system designers and programmers, to more and more distributed and customizable systems." Letztgenannte Eigenschaft kennzeichnet auch das Bibliothekssystem ALEPH 500, das vor zehn Jahren mit der Einführung durch die Vorarlberger Landesbibliothek in Bregenz/ Österreich seinen Einzug in den deutschsprachigen Raum startete. Bereits ein Jahr später wurde die Anwendung von den vier Berliner Universitätsbibliotheken in Betrieb genommen und ist seit 2002 auch in der Senatsbibliothek Berlin im Einsatz. Der wiederholte Kontakt mit dem ALEPH-System - sei es im Rahmen von Literaturrecherche, Praktikum oder universitärem Veranstaltungsangebot - gab Anlass für eine nähere Beschäftigung mit diesem Thema. Ziel der vorliegenden Arbeit ist die Auseinandersetzung mit der Funktionalität von ALEPH-Katalogen und das Herausstellen ihrer Unterschiede im Umfang und in der Ausgestaltung des Angebots hinsichtlich der Ausrichtung auf die Bedürfnisse der Benutzer. Angesichts der gestiegenen Erwartungshaltung in Bezug auf eine schnelle und zuverlässige Informationsbeschaffung soll der Frage nachgegangen werden, in welchem Ausmaß die verfügbaren Möglichkeiten des Softwaresystems ausgeschöpft bzw. zusätzlich ergänzt werden. Die Untersuchung beschränkt sich ausschließlich auf deutschsprachige Kataloge, um aufgrund der ähnlichen Randbedingungen eine bessere Vergleichbarkeit zu gewährleisten. Auf Aspekte der Gestaltung und der Barrierefreiheit wird dabei nicht näher eingegangen, da diese wiederum selbst eigenständige Themengebiete darstellen. Auch der Bereich der Online-Hilfen ist von der Untersuchung ausgenommen, da diese bereits an anderer Stelle ausführlich behandelt wurden. Die Aufbereitung der Ergebnisse betrachtet die untersuchten Online-Kataloge überwiegend in ihrer Gesamtheit, einige beispielhafte Fälle werden zur Demonstration hervorgehoben. Die genauen Resultate sind im Einzelnen erfasst und können der Tabelle im Anhang entnommen werden.

Abstract

Over the past year, innumerable discussions on the relationship between traditional library OPACs and the newly burgeoning World WideWeb have occured in many libraries and in virtually every library related discussion list. Rumors and speculation abound, some insisting that SGML will replace USMARC "soon," others maintaining that OPACs that haven't migrated to the Web will go the way of the dinosaurs.

Abstract

The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

Abstract

The Venice University Institute of Architecture has developed Easyweb, a software package to integrate its heterogeneous non-compatible bibliographic and multimedia databases, standardise access and create internal links, by transferring all existing OPAC applications to the Web. Features include importation of UNIMARC data, multiple window searching, multibase searching and special applications, e.g. circulation management. Easyweb is notable user friendly and has become the point of reference for OPACs in Italy

Abstract

Die verschiedenen unter dem Schlagwort "Bibliothek 2.0" zusammengefassten neuen Dienste und Komponenten wie etwa Wikis, Tagging-Systeme und Blogs sind seit einiger Zeit in aller Munde und dringen über Fortbildungsveranstaltungen, Konferenzen und Publikationsorgane immer mehr in das deutschsprachige Bibliothekswesen ein. Darüber hinaus gibt es öffentlich geförderte Projekte zu bibliothekarischen 2.0-Themen und sogar ein Projekt, welches sich explizit einen 2.0-Katalog zum Ziel gesetzt hat. In diesem Beitrag soll es nun nicht um die Vorstellung eines weiteren Projekts im Dienste des Themas "Bibliothek 2.0" gehen, ebenso hat dieser Beitrag nicht den Anspruch, die Diskussion über die möglichen Vor- oder Nachteile dieser Thematik auf theoretischer Ebene voranzubringen. Vielmehr wird hier ganz praktisch aus Sicht einer kleinen Universitätsbibliothek, der Bibliothek der Helmut-SchmidtUniversität (HSU) - Universität der Bundeswehr Hamburg, aufgezeigt, wie das Thema "Web/Bibliothek 2.0" durchaus neben und in Unterstützung von weiteren nutzerorientierten Servicedienstleistungen auch in kleinen Schritten positive Auswirkungen für die Nutzerinnen und Nutzer haben kann. Der Focus wird dabei auf dem zentralen Arbeits- und Rechercheinstrument der Bibliotheksnutzer liegen, dem Bibliothekskatalog. Speziell wird es darum gehen, wie auf relativ einfache Art und Weise durch Anwendung verschiedener Elemente anderer Dienste und Anbieter sowie das Aufgreifen von Schnittstellen und wenig aufwendigen Verbesserungen, Mehrwert für die Nutzerinnen und Nutzer zu erzielen ist. Ein zentraler Begriff bei fast allen Überlegungen, die im Zusammenhang mit der Verbesserung und Anreicherung des Kataloges stehen, war und ist das Thema "Mash-up". Unter Mashups - ein Begriff, der gerade im Zusammenhang mit dem Thema "Web 2.0" im deutschsprachigen Raum eingeführt und adaptiert wurde - wird das Verfahren bezeichnet, Web-Inhalte neu zu kombinieren. Dabei nutzt man bei und für Mashups offene "APIs" (Application Programming Interfaces, also offene Programmierschnittstellen), die von anderen Web-Anwendungen zur Verfügung gestellt werden.

"Most Web search engines accept natural language queries, perform some kind of fuzzy matching and produce ranked output, displaying first the documents that are most likely to be relevant. On the other hand, most library online public access catalogs (OPACs) an the Web are still Boolean retrieval systems that perform exact matching, and require users to express their search requests precisely in a Boolean search language and to refine their search statements to improve the search results. It is well-documented that users have difficulty searching Boolean OPACs effectively (e.g. Borgman, 1996; Ensor, 1992; Wallace, 1993). One approach to making OPACs easier to use is to develop a natural language search interface that acts as a middleware between the user's Web browser and the OPAC system. The search interface can accept a natural language query from the user and reformulate it as a series of Boolean search statements that are then submitted to the OPAC. The records retrieved by the OPAC are ranked by the search interface before forwarding them to the user's Web browser. The user, then, does not need to interact directly with the Boolean OPAC but with the natural language search interface or search intermediary. The search interface interacts with the OPAC system an the user's behalf. The advantage of this approach is that no modification to the OPAC or library system is required. Furthermore, the search interface can access multiple OPACs, acting as a meta search engine, and integrate search results from various OPACs before sending them to the user. The search interface needs to incorporate a method for converting the user's natural language query into a series of Boolean search statements, and for ranking the OPAC records retrieved. The purpose of this study was to develop a relevancyranking algorithm for a search interface to Boolean OPAC systems. This is part of an on-going effort to develop a knowledge-based search interface to OPACs called the E-Referencer (Khoo et al., 1998, 1999; Poo et al., 2000). E-Referencer v. 2 that has been implemented applies a repertoire of initial search strategies and reformulation strategies to retrieve records from OPACs using the Z39.50 protocol, and also assists users in mapping query keywords to the Library of Congress subject headings."

Abstract

One finding of the 2006 OCLC study of College Students' Perceptions of Libraries and Information Resources was that students expressed equal levels of trust in libraries and search engines when it came to meeting their information needs in a way that they felt was authoritative. Seeking to incorporate this insight into our own instructional methodology, Schaffer Library at Union College has attempted to engineer a shift from Google to Google Scholar among our student users by representing Scholar as a viable adjunct to the catalog and to snore traditional electronic resources. By attempting to engage student researchers on their own terms, we have discovered that most of them react enthusiastically to the revelation that the Google they think they know so well is, it turns out, a multifaceted resource that is capable of delivering the sort of scholarly information that will meet with their professors' approval. Specifically, this article focuses on the fact that many Google Scholar searches link hack to our own Web catalog where they identify useful book titles that direct OPAC keyword searches have missed.
