Correspondence Chess League of America (although there is a Correspondence Chess League of Australia). It is the oldest and largest postal chess organization in America and second oldest in the world. In 1909, the Correspondence Chess League of Greater New York (CCLGNY) was founded by a group of correspondence players who had been conducting postal chess tournaments since 1897. By 1917, CCLGNY and three other groups merged to create the CCLA. It publishes the largest correspondence chess magazine in the world, The Chess Correspondent, the oldest national magazine in the U.S. The CCLA had the first numerical rating of players in 1940.
