- Abstract
- Describes the construction of improved informetric models of individual scientific and technological areas on the basis of individual co citation clusters. The developed methodology of replenishment of research front with accidently absent papers describes the model more completely. Proposes the simple method of cluster 'dynamization' for the study of evolution of research area. The transition under consideration from co citation clusters to lexical maps of papers and patents enables the monitoring of the relationshuip between R and D in a given technological area. Provides the example from modern chemical engineering of Pressure-Swing Adsorption

- Abstract
- The delimination of a research field in bibliometric studies presents the problem of the diversity of subject classifications used in the sources of input and output data. Classification of documents according the thematic codes or keywords is the most accurate method, mainly used is specialized bibliographic or patent databases. Classification of journals in disciplines presents lower specifity, and some shortcomings as the change over time of both journals and disciplines and the increasing interdisciplinarity of research. Standardization of subject classifications emerges as an important point in bibliometric studies in order to allow international comparisons, although flexibility is needed to meet the needs of local studies

- Abstract
- Reports results of a study, conducted in 8 languages, to examine the reading and library use habits of eminent individuals. All living Nobel Prize Laureates were contacted and asked to provide information about their childhood interests and habits and also those which characterize their adult careers. Respondents indicated that as children they enjoyed reading and many relied on library services to provide them with the material they read. The Laureates who grew up in the USA had more access to library services, tended to make more use of libraries as children, and felt more competent to use libraries at earlier ages than did many of their counterparts outside the USA. The reading habit persisted into adulthood more predictably than did library use or their involvement in other leisure activities

- Reports results of a cocitation analysis study from the international retrieval research field from 1987 to 1997. Data was taken from Social SciSearch, via Dialog, and the top 40 authors were submitted to author cocitation analysis to yield the intellectual structure of information retrieval. The resulting multidimensional scaling map revealed: identifiable author groups for information retrieval; location of these groups with respect to each other; extend of centrality and peripherality of authors within groups, proximities of authors within groups and across group boundaries; and the meaning of the axes of the map. Factor analysis was used to reveal the extent of the authors' research areas and statistical routines included: ALSCAL; clustering analysis and factor analysis

- 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
- WWW and related information technologies are transforming the distribution of scientific and technical information (STI). We examine 11 recent, functioning digital libraries focusing on the distribution of STI publications, including journal articles, conference papers, and technical reports. We introduce 4 main categories of digital library projects: based on the architecture (distributed vs. centralized) and the contributor (traditional publisher vs. authoring individual / organization). Many digital library prototypes merely automate existing publishing practices or focus solely on the digitization of the publishing practices cycle output, not sampling and capturing elements of the input. Still others do not consider for distribution the large body of 'gray literature'. We address these deficiencies in the current model of STI exchange by suggesting methods for expanding the scope and target of digital libraries by focusing on a greater source of technical publications and using 'buckets', an object-oriented construct for grouping logically related information objects, to include holdings other than technical publications

- Abstract
- The relative impact of local research units is obtained by dividing the observed number of citations to their publications by the expected number of citations. It is argued that the expected citation rates used in the standard method cannot lead to relevant bibliometric scores for specific research topics. Extracting information about quality of research with the standard method is, therefore almost impossible. The existence of empirical relations between the number of citations and the number of publications for scientific disciplines and for journals, leads to alternative ways to determine relative impact. Hereby, refernce data are taken from within a given research topic. Only observed citation and publication (activity) patterns for research topics are taken into account for calculating bibliometric scores. The new methods are not restricted to ISI-publications. The rsulting bibliometric scores can contain information about the quality of research, and lead to different rankings than those obtained with the standard methods, although the same citation and publication data are used
