Define Bradford‟s Law. Discuss how it can be applied in library and information services with examples

Bradford's law states that a small core of, for example, journals haveas many papers on a given subject as a much larger number of journals, n, whichagain has as many papers on the subject as n

journals.Bradford himself provided both a graphical and a verbal formulation of his law thathave later been found not to be mathematical equivalent. The exact mathematicalfunction has been subject to much subsequent research, and the very question what aBradford distribution is has been debated. As the distribution is very sensitive to dif-ferent subjects and conventions, Heine  found that it is unclear under which cir-cumstances a distribution should be regarded as a Bradford distribution.Bradford's law has been used as an argument about how to build collections, howto select journals to be indexed in bibliographies, how to measure the coverage of bibliographies, how to solve practical problems related to information seeking andretrieval, and by Bradford himself as an argument for a new way to organize biblio-graphical work and scientific documentation.Bradford's law is explicitly about the scattering of documents on specific subjects.The meaning of the term "subject" ___ _________ ________ ______ ________ ________ ______ ___ _________ _____ _____.
