Journal of the American Society for Information Science and Technology, 2010
AbstractNaranan's important theorem, published in Nature in 1970, states that if the number of journals grows exponentially and if the number of articles in each journal grows exponentially (at the same rate for each journal), then the system satisfies Lotka's law and a formula for the Lotka's exponent is given in function of the growth rates of the ...

A relationship between Lotka's Law, Bradford's Law, and Zipf's Law

Journal of the American Society for Information Science, 1986
A common functional relationship among Lotka's law, Bradford's law, and Zipf's law is derived. The proof takes explicit account of the sequences of observed values of the variables by means of an index. This approach results in a more realistic and precise formulation of each law. © 1986 John Wiley & Sons, Inc.

An empirical examination of Lotka's law

Journal of the American Society for Information Science, 1986
There were 48 sets of author productivity data tested against Lotka's Law of xnmiddot;y = c. Overwhelming conformity to the law was found. However, only seven data sets fitted the inverse square law. For future tests, representative coverage and good sampling techniques should be adhered to in data compilation.
