Bradford's Law in bibliometrics is viewed as consisting of two aspects. First one is the distribution aspect which is purely a mathematical pattern. The other aspect is the relevance of such a distribution to bibliometrics. This paper deals with the methodology for estimating Bradford groups within a given set of bibliometric data. The paper also proposes a simple and easily adaptable statistical search method (SSM) and illustrates the application of the method.

Bradford's Law in bibliometrics is viewed as consisting of two aspects. First one is the distribution aspect which is purely a mathematical pattern. The other aspect is the relevance of such a distribution to bibliometrics. This paper deals with the methodology for estimating Bradford groups within a given set of bibliometric data. The paper also proposes a simple and easily adaptable statistical search method (SSM) and illustrates the application of the method.
