These scorebooks cover home and away games of the Chicago White Sox and the Chicago Cubs. Also included are Spring Training, World Series, and Chicago City Series games. There are a few amateur games between the Glen Ellyn Post and various teams, such as the South Shore BBC, West Chicago BBC, and Shamrock's BBC. There's a game between the Sheriff's Office and the Assessors' Office. In 1907, there's a forfeited game between the Cubs and Cardinals, with the umpire claiming the Cubs did not have nine men on the field, but Gilruth notes that this is not the case.
