The Winter Meetings have been Organized Baseball's annual offseason ritual since the early days of the game. This is SABR's second volume on their history, covering 1958 - 2016, plus a special section on the Negro Leagues winter meetings. The latter years of the 20th century included many monumental changes in the business of baseball. This volume covers multiple rounds of expansion, the advent of free agency, several work stoppages, collusion among the owners, and the elimination of the American and National League presidents' offices and consolidation of the two leagues as a single business entity.
