The Sporting News Baseball Guide
The Sporting News Baseball Guide was published every year from 1942 to 2006. Published by The Sporting News, it was baseball's official record in its first year, but lost the "official" designation due to a falling-out between Sporting News owner J.G. Taylor Spink and Commissioner Kenesaw Mountain Landis. Spink continued to publish his guide, competing with the Commissioner's Guide (1943 Baseball) and Official Baseball. In 1947, after Landis's death, the Sporting News Guide regained the "official" tag and was the sole and undisputed almanac for professional baseball statistics for four decades.
