- Abstract
- The World Wide Web (simplified here to "Web") is well-known for its "point and click" graphical user interface (GUI) and hyperlink search and navigate capabilities. When OPACs are placed in this operational context, users can easily hyperlink from a bibliographic display to related search terms, class marks, or bibliographic records. This hyperlinking capability is not available in most conventional text-based OPACs. As more and more users undertake their searches on Web-based information retrieval systems such as OPACs, it is natural to ask, "Are Web-based OPACs more effective retrieval systems than their conventional predecessors?" This paper presents the findings of an experimental study which compared users' search performance, assessments of ease of use, and satisfaction with search results after use of a Web OPAC or its conventional counterpart. The primary questions addressed by this research center on the influence of two experimental factors, OPAC search interface style and search task level of difficulty, on the dependent variables: actual search performance, perceptions of ease of use, and user assessments of satisfaction with search results. It was hypothesized that Web OPACs would be assessed as easier to use and that they would outperform conventional OPACs when measured by actual search results and users' levels of satisfaction with search results. Web OPAC searchers outperformed Text OPAC searchers, but search task level of difficulty is a major determinant of search success. The study also found little association between searchers' level of satisfaction with results and actual search performance

- Abstract
- Elektronische Bibliothekskataloge und Bibliografien haben ihr Monopol bei der Suche nach Büchern, Aufsätzen, musikalischen Werken u. a. verloren. Globale Suchmaschinen sind starke Konkurrenten, und Bibliotheken müssen heute so planen, dass ihre Dienstleistungen auch morgen noch interessant sind. Die Deutsche Bibliothek (DDB) wird ihre traditionelle Katalogrecherche zu einem globalen, netzbasierten Informationssystem erweitern, das die Vorteile der neutralen, qualitätsbasierten Katalogsuche mit den Vorteilen moderner Suchmaschinen zu verbinden sucht. Dieser Beitrag beschäftigt sich mit der Verbesserung der inhaltlichen Suchmöglichkeiten im Informationssystem Der Deutschen Bibliothek. Weitere Entwicklungsstränge sollen nur kurz im Ausblick angerissen werden.

- Abstract
- In one form or another, from a mental list in the mind of the librarian, to book catalogs, card indexes, and online information retrieval systems, some type of meta access has existed to guide library users through library collections. Over the last 40 years, these constructs of paper and wood evolved into Online Public Access Catalogs (OPACs). When the catalog shifted out of drawers and off of three by five cards to become a networked, universally accessible entity, its role in the library shifted as well. The OPAC competes with the World Wide Web, metadata registries, search engines, and more sophisticated database structures for attention. Amongst this assortment of access mechanisms, the purpose of the OPAC has become muddled. The OPAC has now become one information source among many and one of a number of portals for accessing library collections and beyond.

- Abstract
- Although technology can often correct spelling errors, the complex tasks of information searching and retrieval in an online public access catalog (OPAC) are made more difficult by these errors in users' input and bibliographic records. This study examines the search behaviors of 38 university students, divided into groups with either easy-to-spell or difficult-to-spell search terms, who were asked to find items in the OPAC with these search terms. Search behaviors and strategy use in the OPAC and on the World Wide Web (WWW) were examined. In general, students used familiar Web resources to check their spelling or discover more about the assigned topic. Students with difficult-to-spell search terms checked spelling more often, changed search strategies to look for the general topic and had fewer successful searches. Students unable to find the correct spelling of a search term were unable to complete their search. Students tended to search the OPAC as they would search a search engine, with few search terms or complex search strategies. The results of this study have implications for spell checking, user-focused OPAC design, and cataloging. Students' search behaviors are discussed by expanding Thatcher's (2006) Information-Seeking Process and Tactics for the WWW model to include OPACs.

- Abstract
- The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

- Abstract
- Ausgangslage Die Katalog-Recherchen über Internet, also von außerhalb der Bibliothek, nehmen erwartungsgemäß stark zu bzw. sind mittlerweile die Regel. Damit ist natürlich das Bedürfnis und die Notwendigkeit gewachsen, über den Titel hinaus zusätzliche inhaltliche Informationen zu erhalten, die es erlauben, die Zweckmäßigkeit wesentlich besser abschätzen zu können, eine Bestellung vorzunehmen oder vielleicht auch 50 km in die Bibliothek zu fahren, um ein Buch zu entleihen. Dieses Informationsdefizit wird zunehmend als gravierender Mangel erfahren. Inhaltsverzeichnisse referieren den Inhalt kurz und prägnant. Sie sind die erste Stelle, welche zur Relevanz-Beurteilung herangezogen wird. Fast alle relevanten Terme einer Fachbuchpublikation finden sich bereits dort. Andererseits wird immer deutlicher, dass die dem bibliothekarischen Paradigma entsprechende intellektuelle Indexierung der einzelnen dokumentarischen Einheiten mit den engsten umfassenden dokumentationssprachlichen Termen (Schlagwörter, Klassen) zwar eine notwendige, aber keinesfalls hinreichende Methode darstellt, das teuer erworbene Bibliotheksgut Information für den Benutzer in seiner spezifischen Problemstellung zu aktivieren und als Informationsdienstleistung anbieten zu können. Informationen zu sehr speziellen Fragestellungen, die oft nur in kürzeren Abschnitten (Kapitel) erörtert werden, sind derzeit nur indirekt, mit großem Zeitaufwand und oft überhaupt nicht auffindbar. Sie liegen sozusagen brach. Die Tiefe der intellektuellen Indexierung bis in einzelne inhaltliche Details zu erweitern, ist aus personellen und damit auch finanziellen Gesichtspunkten nicht vertretbar. Bibliotheken fallen deshalb in der Wahrnehmung von Informationssuchenden immer mehr zurück. Die enorme Informationsvielfalt liegt hinter dem Informations- bzw. Recherchehorizont der bibliographischen Aufnahmen im Katalog.

- 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
- Recherche in Bibliothekskatalogen war, zumindest in deutschen Bibliotheken, bis zur Mitte des 20. Jahrhunderts in der Regel Sache des Personals, eine wirklich erfolgreiche Recherche meist Spezialisten vorbehalten. Nur diese waren in der Lage, häufig unter Einbeziehung diverser Hilfsmittel, Titelwünsche der Leser nach den jeweiligen Katalog- und Bibliotheksregeln in entsprechende Kataloganfragen umzusetzen. Als dann den Bibliothekskunden selbst nach und nach der Zugang zu diesen Zettelkatalogen in den Bibliotheken eröffnet wurde, war für eine erfolgreiche Suche meist "guter Rat teuer". Hilfestellung und "guter Rat", oft schon bei einer simplen Titelsuche wie "Schuld und Sühne" nötig, konnte vom uneingeweihten Leser direkt vor Ort in der Bibliothek eingeholt werden. Elektronische Formen der Kataloge in Bibliotheken, kurz "OPACs" genannt, eröffneten neue, den alten Zettel- und Mikrofichekatalogen völlig unbekannte Suchmöglichkeiten. Sie zogen aber auch neue Fragestellungen nach sich, besonders zum Handling und zur Suchstrategie. Zumindest dem "fragemutigen" Nutzer konnte und kann dabei vor Ort in den Bibliotheken immer noch direkt geholfen werden. Diese Hilfestellung entfällt jedoch bei allen Bibliotheks- und Verbundkatalogen, die im Internet als so genannte "Web-OPACs" angeboten werden. Sie erreichen einen viel größeren, dafür aber anonym bleibenden Interessentenkreis, vom absoluten Bibliothekslaien bis zum kundigen Bibliotheksnutzer. Diese aktiven und potentiellen Nutzer treten mit den unterschiedlichsten Anforderungen und Fragestellungen an solche Web-OPACs heran. Ein Web-OPAC muss demnach so gestaltet sein, dass er für Laien und Profis gleichermaßen nutzbar ist und dabei möglichst wenige Fragen überhaupt erst aufkommen lässt, im Idealfall also über eine selbsterklärende Oberfläche verfügt. Hilfetexte müssen die nicht vorhandene persönliche Hilfestellung kompensieren helfen. Sie sind also übersichtlich, verständlich und zielgerichtet einsetzbar zu gestalten.

- Abstract
- The development of networked access to academic library catalogue records has been conspicuously slow compared with that of campus wide information systems in general. In cooperation with its systems suppliers BLCMO, the Pilkington Library, Loughborough, UK, is seeking to remedy this situation by developing an interface that allows users to access its OPAC via the W3. The benefits of such a facility are reflected in BLCMP's decision to incorporate a revised version in the forthcoming release of the commercial Talis system; but problems relating to the 'statelessness' of hypertext tranfer protocol (HTTP) and to the inadequacy of traditional catalogue records as access points for electronic information resources are still causes for consideration

- Abstract
- Das Projekt "KOBV-Informationsportal" In den vergangenen Jahren hat der Kooperative Bibliotheksverbund BerlinBrandenburg (KOBV) mit der KOBV-Suchmaschine eine Internet-Plattform mit einer offenen Architektur geschaffen. Auf dieser technischen Basis erweitert er kontinuierlich sein Dienstleistungsangebot, wobei die Prinzipien des KOBV - insbesondere Offenheit, Heterogenität und Dezentralität auf technischer und organisatorischer Ebene - gewahrt bleiben. Mitte 2001 hat die KOBV-Zentrale gemeinsam mit den regionalen Bibliotheken das zweite große Entwicklungsprojekt "KOBV-Informationsportal" gestartet. Zielsetzung war der Aufbau eines kooperativen regionalen Portals mit Einsatz von Linking-Mechanismen zur "nahtlosen" Navigation in freien und lizenzierten Dokumenten und mit Einsatz von Instrumenten zur dezentralen Authentifizierung und Autorisierung über das Internet. Im Dezember 2003 hat das "KOBV-Portal - Digitale Bibliothek Berlin-Brandenburg" planmäßig in einer ersten Ausbaustufe den Routinebetrieb aufgenommen. Das KOBV-Portal bietet in dieser Stufe den Nachweis über die in den großen Bibliotheken lizenzierten Ressourcen und elektronischen Zeitschriften, zudem die nahtlose Navigation mittels des Reference-LinkingWerkzeuges SFX zu verschiedenen Diensten wie Fernleihe, Subito und freien Volltexten im Internet sowie zu frei zugänglichen elektronischen Zeitschriften. Die mit der verteilten Authentifizierung und Autorisierung verbundene Zielsetzung konnte im Rahmen des Projektes erst zum Teil umgesetzt werden. Realisiert wurde die Remote-Authentifizierung, mit der sich ein Nutzer, der online eine Fernleih-Bestellung aufgeben möchte, über das Internet in seiner Heimatbibliothek authentifizieren kann. Des weiteren ist der Zugriff auf lizenzierte Bestände im Campus einer Hochschule mittels IP-Checking möglich. Als weiteren wesentlichen Bestandteil des KOBV-Portals hat die KOBVZentrale mit den Bibliotheken einen Workflow für ein Metadata-Sharing abgestimmt und für die Adaption und Normalisierung lokaler Metadaten aus lokalen Bibliothekssystemen und -Portalen den KOBV-Metadaten-AustauschParser (KMA-Parser) entwickelt. Darüber hinaus sollen Bibliotheken, deren Metadaten bislang lediglich in unstrukturierter Form vorliegen, in die Lage versetzt werden, strukturierte Metadaten anzulegen, zu liefern und nachzunutzen. Dazu hat die KOBV-Zentrale das mit einer Web-Katalogisierungsschnittstelle ausgestattete "Metadata-Tool" entwickelt, das im Herbst 2004 in Betrieb genommen wird. Die für das Metadata-Sharing entwickelten Komponenten und Module sollen den Bibliotheken die Mehrfacherfassung ersparen und ihnen die Möglichkeit der wechselseitigen Nachnutzung der Metadaten eröffnen.

- Abstract
- The rapid pace of OPAC implementation in this country is providing a fruitful environment for research, with a wide range of projects currently being undertaken, including a number concerned with the application of advanced information retrieval techniques to OPAC systems. This article reviews the current situation and describes some of the more important research projects being undertaken, particularly those funded by the British Library Research and Development Department. A brief description of the British Library's own OPAC project is also provided. The article concludes with an examination of the value of OPAC research and a look at where further research effort might best be concentrated
