AB Lotka's Law is a widely observed distribution of authors of
   scholarly papers and patents. Numerous studies over the past
   seventy years have found Lotka's Law describes production in
   fields as diverse as chemistry, economics, history, information
   science, musicology, patents and psychology. But previously the
   parameters for Lotka's Law were not linked to variables that
   could be measured or estimated during an individual's career.
   Here we show that the statistics of exceedances generates
   Lotka's Law. Specifically, the Frequency of production (papers
   or patents per year) and Lifetime (career duration) are
   exponentially distributed random variables. Empirical,
   phenomenological and mathematical development shows that, when
   suitably weighted, the product of Frequency and Lifetime
   produces Lotka's Law. (C) 1998 Elsevier Science Ltd. All rights
