Abstract: An empirical law for the rank-order behavior of journal impact 
factors is found. Using an extensive data base on impact factors including 
journals on education, agrosciences, geosciences, mathematics, chemistry, 
medicine, engineering, physics, biosciences and environmental, computer 
and material sciences, we have found extremely good fittings outperforming 
other rank-order models. Based in our results, we propose a two-exponent 
Lotkaian Informetrics. Some extensions to other areas of knowledge are 
discussed. (c) 2007 Elsevier Ltd. All rights reserved.
