- Abstract
- In the DDC Online Project, subject searching and browsing of DDC schedules and relative index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strenghts and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs.

- Abstract
- Nicht nur das traditionelle bibliothekarische Auskunftsinterview, sondern auch die Befragung bzw. Beratung, die im Zusammenhang mit der bibliothekarischen Dienstleistung des Online Information Retrieval zwischen Rechercheur und Endbenutzer abläuft, ist in der Literatur vielfach praxisbezogener, aber auch theoretischer Abhandlungen. Der gesamte Interviewprozeß läßt sich in 4 Phasen gliedern, deren zweite, das der Recherche vorausgehende 'Presearch-Interview' im engeren Sinn, für das Gelingen der Online-Suche besonders wichtig ist. Die dabei inhaltlich und formal wesentlichen Aspekte können in Form praktischer Gebrauchsanweisungen aufgelistet werden. Weiter sind Interview-Stil und -Verhalten von Bedeutung; auftretende Kommunikationsbarrieren können durch Einsatz nichtverbaler Kommunikationstechniken und einfühlsames Beraterverhalten überwunden werden. Eine neue Variante des Auskunftsinterviews ist das sog. 'Presearch-Counseling', das bei der Beratung von Bibliotheksbenutzern, die endbenutzergerechte Online-Retrievalsysteme verwenden, erforderlich sind

- Abstract
- Auf dem Hintergrund der aktuellen OPAC-Entwicklung in Deutschland werden im ersten Teil einzelne Aspekte des OPAC-Designs kommentiert. Es wird u.a. auch auf Möglichkeiten einer Standardisierung der Schnittstelle Retrieval-Software / Benutzeroberfläche eingegangen. Die derzeit dominierenden Online-Kataloge sind für eine Massenbenutzung nur bedingt geeignet, da sie in hohem Maße fehlerintolerant sind, eine Analyse nach Suchfeldern verlangen und mit grundsätzlichen Mängeln der Boole'schen Suchlogik behaftet sind. Im zweiten Teil werden werden Alternativen diskutiert, zum einen in Form eines alphabetisch sortierten Online-Katalogs, zum anderen in Form intelligenter bibliographischer Auskunftssysteme, die Ähnlichkeitssuchen bzw. sog. 'Closest-Match-Suchen' gestatten. Hierzu werden verschiedene Konzepte und Vorschläge vorgestellt

- Abstract
- Designing research on the retrieval effectiveness of computer searches on PRECIS compared with retrieval effectiveness of searches on other types of subject analysis used in computer-based information sources is a complex process. This paper explores the complexity of measuring comparative retrieval effectiveness through a comparison of the subject analysis provided by the PRECIS system for fifty articles with the subject analysis provided for the same articles by three computer-based information sources: ERIC/CIJE, LLBA/Online and PsycINFO. Objectives are: (1) to discover factors that should be taken into account when designing this type of research; and (2) to identify extraneous variables that work against internal validity in research design .

- Abstract
- A research project in progress at Middlesex Polytechnic is examining the problems of providing adequate subject access from MARC-based cataloguing systems. Various forms of printed index are being evaluated and an experimental OPAC is being designed. The PRECIS RIN file will be tested as a basis for online thesaural control and as a browsing facility

- Abstract
- Optimal retrieval in on-line searching can be achieved through combined use of both natural language and controlled vocabularies. However, there is a large variety of types of controlled vocabulary in data bases and often more than one in a single data base. Optimal use of these vocabularies requires understanding what types of languages are involved, and taking advantage of the particular mix of vocabularies in a given data base. Examples 4 major types of indexing and classification used in data bases and puts these 4 in the context of 3 other approaches to subject access. Discusses how to evaluate a new data base for various forms of subject access.
