Abstract
This paper examines the obsolescence of literature produced on Lotka’s law up to 2010, over which time no definitive pattern of obsolescence is discernible. Cumulative data since then, however, shows a pattern of obsolescence at an annual rate of decrease of 9%, with a duplication rate of 17.4 years. These statistics indicate a good fit with the exponential model, with an R2 of 0.985 at asignificance level of 0.01.
