- Abstract
- Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

- Abstract
- Information retrieval systems such as library OPACs have been largely designed to give the impression of being single user systems, the existence and activity of other users being hidden from each other. However, informal observations indicate significant collaboration between users despite the fact that existing systems fail to support this. Describes the development of an interface, the Ariadne system, that supports collaboration through the storage and re-use of others' search processes promoting better visualization of the information data structures being browsed and more effective means of communicating the browsing process. Discusses issues relating to privacy and ownership resulting from the storage of users' searches. Argues that introducing support for collaboration into information retrieval systems would help users to learn and use the systems more effectively

- Abstract
- Examines the advantages and disadvantages of precoordinated, postcoordinated and automatic indexing with regard to existing information storage systems, such as card catalogues, OPACs, CR-ROM databases, and online databases. Presents a general model of document content representation and concludes that the library profession needs to address the development of databank design models, relevance feedback methods and automatic indexing assessment methods, to make indexing more effective

- Abstract
- To an overwhelming extent, storage and retrieval systems were designed for information intermediaries who were specialists in formal, controlled documentation languages (e.g. classification systems, indexing languages) and who were then trained to utilize the query language of each retrieval system. However, with the advent of the microcomputer, there now exists, in the information retrieval industry, an obvious will to tackle both the professional and the personal information markets, as evidences by their more sophisticated yet more user-friendly systems and by the design and marketing of all sorts of interface software (front-end, gateway, intermediary). In order to make full advantage of these systems, the user must be able to master three different languages: the natural language of the discipline, the indexing language, and the system's query language. The author defines and characterizes each of these languages and identifies their issues and trends in the IR cycle and specifically in public online search services. Finally he proposes a theoretical model for the analysis of IR languages and suggests a few research avenues

- Abstract
- Online catalogues and card catalogues can be compared from different perspectives and according to different criteria. Compares the 2 types of catalogue according to the processes in which bibliographic records are created (input stage), manipulated (storage stage) and retrieval (output stage). The concepts underlying these stages are studied, revealing major differences between online and card catalogues, which are multiplied and widened when moving from input and output stage to such an extent that online catalogues can be considered as a significant departure from manual catalogues. The redesign for use in the online environment of bibliographic standards (cataloguing codes, MARC formats and ISBDs) which have been based on the concept of the card catalogue should instead be based on the conceptual as well as the practical differences between the online and the card catalogue

- Abstract
- This paper describes the Book House system which is designed to support children's information retrieval in libraries as part of their education. It is a shareware program available on CD-ROM and discs, and comprises functionality for database searching as well as for the classification and storage of book information in the database. The system concept is based on an understanding of children's domain structures and their capabilities for categorization of information needs in connection with their activities in public libraries, in school libraries or in schools. These structures are visualized in the interface by using metaphors and multimedia technology. Through the use of text, images and animation, the Book House supports children - even at a very early age - to learn by doing in an enjoyable way which plays on their previous experiences with computer games. Both words and pictures can be used for searching; this makes the system suitable for all age groups. Even children who have not yet learned to read properly can by selecting pictures search for and find books they would like to have read aloud. Thus at the very beginning of their school period, they can learn to search for books on their own. For the library community itself, such a system will provide an extended service which will increase the number of children's own searches and also improve the relevance, quality and utilization of the collections in the libraries. A market research on the need for an annual indexing service for books in the Book House format is in preparation by the Danish Library Center
