Abstract  

This is to assess the applicability of the Bradford distribution to an international science-technology indicators problem. The Bradford distribution which has been empirically known to be valid for the number of scientific articles on a given research topic across journals is applied to the number of scientific articles in a given research field across nations. The Bradford distribution is herein found to provide information of the degree of scientific-technological inequitability between advanced and latecomer nations and, more characteristically, a method for classification of nations into core, middle and peripheral classes with respect to their S&T selfreliance. This may suggest the usefulness of the Bradford distribution for anylsis of international science-technology indicators. Some theoretical discussions on mathematical properties of the Bradford distribution are given.
