Bradford Distribution
Dr. Atta-ur-Rahman contributed 766 publications during the entire period of
productivity (1966- June 2007). For the ten publications the names of channels of
communication are not mentioned. To test for the remaining 756 publications
whether his contribution follows Bradford distribution or not, the productivity is
divided into three zones each having approximately 252 papers.
The first 4 channels published 253 titles, the next 16 published 250 while in case
of 3 rd zone 64 channels published 253 publications. The below table provides
zone-wise distribution of publications and journals.
Bradford multiplier is 4 in this case. According to this multiplier the number of
publications in the third zone should be 4x4x4 = 64 which is exactly the same as
actual number 64. Thus the data follows the Bradford Law of distribution, Garfield,
E. (1979).
