Scientometrics, 1984 Two models of the mechanism responsible for the distribution of scientific papers in an area over periodicals are given. Empirical distributions following Bradford's law are shown to agree quite closely with a lognormal distribution. This distribution arises, in one model, by taking the probability of a paper being published in a particular journal as ...

Bradford's law: An index approach
Scientometrics, 1987 A rigorous analysis of Bradford's law is made using an index for the observed values of the variables. Three important properties relating size and frequency are identified. Using this approach, the shape of Bradford-type curves can be described in terms of three distinct regions and two shape parameters.

Evaluation of the models for Bradford's law
Scientometrics, 1998 A goodness of fit test is conducted for two models for Bradford's law given byEgghe andSmolkov. The conclusion is that Smolkov's model is of comparatively higher accuracy. Finally the paper points out the necessity of carrying out statistical tests for comparisons more frequently for the new models of Bradford's law in the development of the law in ...

Journal of the American Society for Information Science, 1986 In this article, we examine the classical law of Bradford. This law yields groups with an equal number of articles, but where the number of journals increases geometrically. Within each group, and starting with the last ones (the least productive journals) we examine the maximal productivity of the journals.

The yield formula and bradford's law
Journal of the American Society for Information Science, 1976 AbstractThe relation between a number of n top producing journals and their cumulative yield R(n)—articles, loans—is expressed by a yield graph (Figs. 1 and 3). Graphically, by linearization of the yield graph (Figs. 2 and 4), the following yield formula is deduced (Fig. 5): \documentclass{article}\pagestyle{empty}\begin{document}$ R\left(n \right) = h\

On the naranan interpretation of Bradford's law
Journal of the American Society for Information Science, 1976 AbstractThe Naranan interpretation of the original form of Bradford's Law does not follow from a stochastic argument based on his assumptions.

Bradford's Law in the Context of Information Provision
Scientometrics, 2000 The aim of the study is to study empirical use of Bradford's law for decisions concerning information systems in problem based fields, were journals from different disciplines cover relevant information. Results of comparison of the cores in different fields can be used as a base for tailoring an information system.

Bradford’s Law and the Nigerian Entomological Literature
International Journal of Tropical Insect Science, 1984 —Journal citations in Bibliography of entomological research in Nigeria: 1900–1973 were subjected to Bradford analysis with the view of evaluating the completeness of the bibliography and determining the core journals and core authors. As to the completeness of the bibliography, it was inferred that the bibliography is 93% complete in terms of journals

“Bradford's law” and the relationship between ecology and biogeography
Scientometrics, 1990 Core journals in ecology and biogeography were identified on the basis of Bradford's Law of Scattering, and their degree of overlap measured as percentage Similarity (PS). Areas of common interest between the two disciplines, as well as of uniqueness, were determined through bibliometric analysis of these core journals.
