Society For American Baseball Research – The Society for American Baseball Research had its beginnings in Cooperstown, New York. It was the brainchild of L. Robert Davids, who on August 10, 1971, gathered 15 other baseball researchers at the National Baseball Hall of Fame to form the organization. From this modest start, SABR membership has broadened steadily. A decade later, it had reached 1,500; today, it totals more than 6,000 worldwide. Who belongs to SABR? Many major and minor league baseball officials, broadcasters and writers, as well as numerous former players. Primarily, the membership consists of “just plain fans” — anyone interested in baseball can join. While the original purpose of SABR was to band together baseball historians, statisticians and researchers, it is not necessary to engage in research to become a member.
