In “The Kentucky Derby, Preakness and Belmont Stakes: A Comprehensive History,” author Richard Sowers made good on both the length of the title and the promise it conveyed. From the birth of the Belmont in 1867 to the series of 2013, when Orb, Oxbow, and Palace Malice cut the Triple Crown three ways, Sowers goes granular on just about every piece of historical data imaginable. There are pictures, too.
