The growth of literature produced on Lotka's law from 1922 to 2003, as well as the growth of authors producing that literature, is analyzed. The growth of literature follows an exponential model with an annual average of 7.5% growth and doubling its size every 9.6 years. The number of authors producing this literature grows at a rate of 7.3% per year and duplicating its volume every 10 years. The statistics indicate a good adjustment to the exponential model, with R² of 0.985 for literature and 0.992 for authors, both at a level of 0.01 significance.
