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.

Author inflation leads to a breakdown of Lotka's law

Journal of the American Society for Information Science and Technology, 2001
AbstractIt is empirically shown that, even using the normal or total counting procedure, Lotka's law breaks down when articles with a large, i.e., more than hundred, number of authors are included in the bibliography. The explanation of this phenomenon is that the conditions for an application of the basic success‐breeds‐success model are not fulfilled

Lotka's law: A testing procedure

Information Processing & Management, 1985
Abstract Instead of the commonly accepted inverse square law, Lotka's original formulation was based on a more general inverse power law: x n · y = c . The exponent and the constant must be estimated from the given set of author productivity data. A step-by-step outline is presented for testing the applicability of Lotka's law.

A new model that generates Lotka's law

Journal of the American Society for Information Science and Technology, 2001
AbstractIn this paper, we develop a new model for a process that generates Lotka's Law. We show that four relatively mild assumptions create a process that fits five different informetric distributions: rate of production, career duration, randomness, and Poisson distribution over time, as well as Lotka's Law.
