This account of the four baseball seasons of 1900 through 1903 seeks to capture the flavor of the period by providing yearly overviews from the standpoint of each team and by focusing more deeply on 30 or more players of the era--not only such legendary stars as Cy Young and Willie Keeler, but also relative unknowns such as Bill Keister and Kip Selbach. Each team section is supplemented by a table providing the significant batting and pitching statistics for each regular team member.

The major theme of the period was the baseball war between the National and American leagues from 1900 to 1903. But the broad multi-season, multi-team view allows varying the focus. The pennant races receive due attention but there are other aspects of the baseball drama, such as: the aging star who finds a way to extend his period of dominance (Cy Young); the young, unpolished phenom whose raw talent enables him to excel (Christy Mathewson); and the fierce competitor who risks injury to help his team (Joe McGinnity or Deacon Phillippe).
