Abstract

The bibliographic data on cancer literature of Nigeria was drawn from the Medline of National Library of Medicine (NLM), USA. This research work examines the conformity of Lotka’s Law to authorship distribution during 2008-2012.Totally, 677 articles in cancer produced by 1,854 authors, was compiled for the analysis. Lotka’s inverse power Law was used in testing the hypotheses. That is,  where the values of the exponent n and the constant c were computed; and Kolmogorov-Smimov (K-S) goodness-of-fit test was applied. The results suggested that all categories of author productivity distribution in this research work fit into Lotka’s generalized inverse square law.
