A chronological history of the Negro Leagues from 1862 to 1948 lists the statistics of every pitcher and batter, team records, significant games and advances for black players, and box scores.
A thorough history of the Negro Leagues, although poorly laid out in my opinion. And ending in 1949, when the Negro League actually limped along into the '60s, makes it really an incomplete history. Correct the layout and extend the scope (and correct a few errors that were obvious to me even just scanning) and you add at least one star to my review.
