The author number method has been part of the AngloAmerican
library tradition since the 1870s when this method started
to be widely discussed in professional publications and continued
to be supported by the creation of author number tables. The best
known tables are those created by Cutter: Cutter Two Figure Author
Tables, Cutter - Sanborn Three-figure Author Tables, and Cutter
Three Figure Author Tables. Less known worldwide are author
number schemes created by James D. Stewart, Charles R. Olin,
William S. Merrill, also the Library of Congress Author Number
Table and Special Codes by Bertha Barden.
