Title
Bradford's distribution : from the classical bibliometric 'law' to the more general stochastic models
Source
Journal of the American Society for Information Science. 48(1997) no.9, S.833-842
Year
1997
Abstract
Outlines some of the important tendencies that helped the shift from the conceptual framework within which the Bradford distribution has been usually considered i.e. to bring it to a par with some well-known distributions and laws within and outside bibliometrics. Focuses on those oriented toward more fundamental problems such as the implementation of general models that can explain the process by which the Bradford and the related distributions are generated. Shifting of the focus and scope to these issues represents a strong current tendency, though some of the basic assumptions regarding this had been advanced about 50 years ago. Discusses the reasons for their slow implementation in the research concepts
