The nicknames for over 3,600 players, umpires, managers, owners, broadcasters, writers, executives, other officials, and fans are included in this comprehensive reference work. Each entry provides the given name of the individual, nickname, position, years played (or associated with the game for nonplayers), and origin of the nickname. A separate section (compiled by Brenda S. Wilson) lists players and nicknames for the All American Girls Baseball League. An extensive name index completes the work.
