/ With the demise of the Spalding-Reach guides after the 1942 edition, the Commissioner’s office put out the official 1943 guide for one season before handing off the "official" guide to A.S. Barnes for the 1945 and 1946 editions. This was colloquially known as the "Barnes Baseball Guide". Since there was no official 1944 guide, the 1945 Barnes guide covers both seasons. The Sporting News took over as the official guide starting with their 1947 edition.
