Bibliometric methods in general undervalue technological research. This study examines the relation in literature between technological/industrial journals and scientific journals in the case of the plastics industry and polymer science. Trade-journals cannot be used in a straightforward bibliometric manner, but can be an aid in mapping the different groups and reveal the hidden communication between technological and scientific communities.
Knowledge and literature of neuroscience started growing steadily during the last few centuries. This paper aims to study the growth of knowledge in neuroscience as well as its literature. The first part of the paper, enumerates a historical survey of the growth of knowledge based on published data. This is done in view of the fact that a consolidated information at one place will be of great value to the students of scientometrics and also to the research scholars who are desirous to undertake research in this discipline. The second part of the paper is entirely based on experimental data which were collected to analyse the growth of literature of the subject.Neuroscience is notable for its wide range of approaches and techniques. In no other branch of research such a manysided approach is so essential. As a consequence last few decades have witnessed an accelerated research tempo and unprecedented growth of the literature on the subject covering its different sub-fields with gradual and systematic transgression of the conventional boundaries between them. To cope with the growth of literature, a new bibliometric technique has been applied to rank periodicals in the field based on 5785 citation data collected from the bibliographic data base published in the source journal namely,Annual Review of Neuroscience. It is expected that this list will reflect the impact of literature on the advancement of knowledge in the field of neuroscience. A striking feature of this study is the comparatively small contribution (8.8%) coming from the application of biochemical techniques and concepts to neuroscience research which differs from what we had noted earlier in the case of other biomedical disciplines. High position occupied by multidisciplinary science journals brings out the significance of new neuroscience research to science as a whole and confirms the importance of this category of journals in the dissemination of knowledge for the overall growth of science. Relatively low proportion, of citations of journals of medicine, both general as well as specialities, in spite of direct relevance of much work in this field to neurological and mental illness reflects the preponderance of interest in the funcamental aspects of neuroscience research. Like other biomedical disciplines neuroscience literature also exhibits English as the most-preferred lingua franca of the subject; dominance of journals published from USA, UK, Germany and the Netherland; a wide scatter of cited literature showing the multidisciplinary approach characteristic of present-day neuroscience research. The results of this study support Bradford's Law of Scattering and also Sengupta's Law of Bibliometrics. It is expected that the present ranking list will be of great help to the working neuroscientists to select a handful of core periodicals in the field for regular browsing from the viewpoint of their importance and significance as these core journals identify maximum segment of contemporary literature on the topics of direct relevance to their day to day research in the field.
Computerized bibliographic databases have become sufficiently well developed and widely available to researchers that they have become potentially an important source of time series estimates of the growth of scientific literature. This paper uses the GEOREF3 database in such an application to estimation of the growth of geoscience. It is found by comparison with studies previously done from the hardcopy equivalents of GEOREF3 that the computer-derived time series can achieve results similar to their equivalents and do this more efficiently, more inexpensively and more comprehensively. Examples are given for geoscience as a whole, and for the literature related to several mineral commodities: iron ore, lead ore, nickel ore, petroleum and natural gas, radioactive minerals and ores, and zinc ore.
A cross-sectional examination of the fisheries literature for 1978 was made to see how language use patterns were related to communicating research information. An analysis of 884 articles indicated that despite the dominance of English as an international communicative medium, there was a strong national language usage pattern. National language usage was not confined to local fisheries problems, but cut across issues of international importance. For most of the articles the language of publication was directly predictable from the first author's country of residence. However the mismatch between these variables for about six percent of the sample suggested the need for a detailed study of individual cases.
By applying of Bradford's law to analysis of the source documents and their references by classification systems researchers in the world, this paper presents core authors of the field during the period 1981–1990. The findings show that 1) core authors of the international classification systems literature are the Library of Congress, M. Dewey, S. Ranganathan, J. Comaromi, A. Neelameghan, L. Chan and K. Markey; 2) the highly cited authors are linked either to the developers of the classification systems or to a research center, or else they authored the most frequently cited books; and 3) the data confirms to Bradford's law and the unusual rising tail of Bradford distribution is appeared and explained.
An examination was conducted of the distributions produced by historical treatments of three scientific specialties: quantum mechanics, plate tectonics, and endocrinology. A citation analysis approach was employed to generate a frequency distribution for year of publication of literature referenced by historians. The observed values were normalized and tested for goodness of fit to each other using a Pearson goodness of fit test. The results indicated that the three distributions were not equivalent. Other parameters of the three distributions did show similarities using aDunn planned comparison approach. The skewness of the three distributions was very similar and plate tectonics and endocrinology were similar in terms of kurtosis. The major conclusion reached was that there were major differences in the three distributions but some similarities in particular parameters were evident. Additional work is necessary to determine causal factors for the differences as well as similarities.
A non-homogeneous birth process is used to describe the statistical properties of bibliometric citation processes. The model is analysed under special assumptions. Thelife-time distribution, special probabilities and mean value functions are used to characterize differences in the ageing structure of scientific literature, the change of citation impact in time and to analyse predictive aspects of reception processes. The results are applied to selected journals representing one field in science and social science each. The empirical part of the study is based on a 14-year citation history (papers published in 1978 and cited 1978–1991). An intimate, connection between impact and ageing cannot be observed. However, the ageing behaviour seems to be clearly influenced by field characteristics and by special document/journal types, such as letters and short communications.

Scientific meetings have become increasingly important channels for scholarly communi-cation. In several fields of applied
and engineering sciences they are - according to the statements of scientists active in those fields - even more important
than publishing in periodicals. One objective of this study is to analyse the weight of proceedings literature in all fields
of the sciences, social sciences and humanities as well as the use of the ISI Proceedings database as additional data source
for bibliometric studies. The second objective is exploring the use of a further important feature of this database, namely,
of information about conference location for the analysis of bibliometrically relevant aspects of information flow such as
the relative attractivity, the extent of mobility and unidirectional or mutual affinity of countries.
Citation patterns of 400 very highly cited scientific papers are identified and the relationship of citation patterns to literature aging rates is investigated. Standardized citation counts for 1972 through 1980 are used as variables in a cluster analysis which groups papers with similar citation patterns and a discriminant analysis is used to refine the descriptions of clusters and to confirm the results. Among highly cited papers published in 1972, two basic citation patterns are identified: one group is highly cited in the first years following publication and declines in citedness thereafter; the second group reaches its citation peak in the sixth year following publication and declines in citedness in the seventh, eighth, and ninth years of the series. Both groups show general evidence of aging.Price's suggestion that less highly cited papers age more rapidly than more highly cited papers is confirmed.

The purpose of this paper is to present the preliminary results of a bibliometric analysis of AIDS documents as produced on
Sub-Saharan Africa. AIDSLINE 1980-2000 was used to conduct the literature search. In this paper, an analysis was made only
of the records retrieved under "Central Africa". Bibexcel (version 2001) and Microsoft Excel (2000) were used as software
tools to conduct the analysis of the records. Seven countries and 1052 records were identified. Main participating countries
were Democratic Republic of the Congo (527 documents), and Cameroon (271). Results indicated a high pattern of collaboration
through multiple authorship. Most documents were published in English (84.50%) and French (14.73%). Over 57% corresponded
to journal articles. The subject content of the documents was mainly focused on epidemiological, complications, and prevention
& control issues on ‘HIV Infections’ and ‘Acquired Immunodeficiency Syndrome’. Countries behind this productivity were Cameroon,
USA, Democratic Republic of the Congo, France, and Belgium. Comparison of results among Central African countries and among
other developing countries is made by the authors.
