The First Book of Baseball
The first comprehensive baseball book ever published, Haney's (1868) is especially significant not only because it contains "official" rules of the game,but also because it is filled with illustrations covering all aspects of pitching, fielding and baserunning.
The book's author, Henry Chadwick, often called the first serious baseball journalist, is credited with inventing the box score, among other innovations. His guide also contains rules for umpires and scorekeepers, the men tasked with keeping order and statistics during the game.
In addition, the book features the first advertisements for bats, belts, shoes, uniforms and other baseball apparel. There is even a section on how to play baseball on ice!
