- Abstract
- Draws attention to the vast potential of online information databases and to the many new possibilities which advanced search techniques offer those who want to explore databases. Looks at informetrics, an emerging subfield in information science, which is based on the combination of advanced information retrieval and quantitative studies of information flow. Describes 3 studies carried out at the Centre for Information studies at the Royal School of Library and Information Science in Copenhagen, Denmark, to illustrate the scope and nature of informetric analysis

- Abstract
- The paper calls for an integrated approach to information science education where disciplinary interaction is predicated on the forgoing of formal, informal and sustainable links with researchers and pracitioners in other fields. The modern information profession, in order to promote its creativity and to strengthen its development, has to go beyond the traditional roles and functions and should extend the professions' horizons. Thus the LIS education and training programmes must aim to foster professionals who, one day, will create new jobs and not just fill the old ones

- Abstract
- By developing a methodology for on-line citation analysis, the international characteristics of scientific journals have been analysed on the basis of correlations between the geographical distribution patterns of authors, citations and subscriptions. The study covered seven selected LIS journals. Assuming that the numbers of authors and citations in each geographical region follow the Poisson distribution, the hypothesis was tested, that the intensities are proportional to the subscriptions. In most cases the correlation between authors and citations was so positive that the international visibility and impact of the scientific journals can be defined by these two variables. As regards the distribution pattern of subscribers, authors and citations, however, the test showed very weak or no correlations. The analysis of the statistical significance of differences gave some useful data, the importance of which to marketing and publishing strategies is obvious. The paper suggests examining also the knowledge export of journals as an additional criterion for the evaluation of their impact, and the quality of research published in them. The comparison of Journal Impact Factors (JIF) is another contribution of this study, aimed to enhance the use of impact factor analysis with various time intervals. We demonstrate new and flexible ways of using the JIF for diachronous and synchronous analyses. The study brings new dimensions to the discussions of the impact, status and image of scientific journals. It focuses on the utilisation of informetric analysis to go beyond the simplistic use of the JIF and to get a deeper understanding of the "real" impact of international scientific journals and their market.

- Abstract
- The paper examines the developmentss that have taken place during the last decade with respect to the provision of intellectual subject access in information databases storage. The principles of the SAP indexing methodology are outlined and exemplified, leading to a discussion of the consequences for the conception of the physical 'document' versus 'semantic entities' as the basic constructs for storage and multi-dimensional representation of subject matter. Finally, the paper analyzes the impact of very recent technologies which make achievable such access conceptions and mechanisms

- Abstract
- Describes an approach to indexing which seeks to eliminate the shortcoming of the representation of information in existing bibliographic catalogues: Subject Access Project (SAP) indexing which has been used successfully at Lund University and elsewhere. Existing catalogue records have been enriched with terms selected from lists of contents and indexes in books thus facilitating access to specific parts of documents and smaller semantic entites such as chapter titles, subject titles and data in graphic or tabulated form available in a wide range of publications

- SAP indexing for exploring the full thematic context of books and for access to smaller semantic entites
