This subseries dates from 1896 to 1977 and features music about the League's teams and players. It is arranged alphabetically by team name with music about the League as a whole arranged to the front. Music in this subseries primarily dates from the first half of the 20th century and provides extensive documentary and illustrative resources for the history of the American League. Six of the original eight American League franchises are represented by music in this collection. Two pieces were written about the entire American League and include Grace Comiskey's 1905 "American League Two-Step." For expansion teams and franchise shifts, music of note includes "Kansas City A's" written in 1955 after their move from Philadelphia, and "The Blue Jays" written for their first year in the American League (1977).
