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 ...

ON THE UNITY OF BRADFORD'S LAW
Journal of Documentation, 1984It is shown that there is no ambiguity in Bradford's theory of distribution. Starting with the two basic postulates laid down by Bradford, a mathematical expression is derived such that its curve agrees with the experimentally plotted data.

Evaluation of the models for Bradford's law
Scientometrics, 1998A 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 ...

Dynamic behavior of Bradford's law
Journal of the American Society for Information Science, 1995This paper examines two problems associated with Bradford's law: (1) Since empirical data deviate from the law in many applications, what are the significant factors influencing the Bradford graphs? (2) What will be the evolution over time of the Bradford graphs?

Bradford's law: An index approach
Scientometrics, 1987A 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.

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.
