Wallace's Year-Book of Trotting and Pacing in ...

Wallace's Year-Book of Trotting and Pacing was established in the late 19th century by John Hankins Wallace to provide a systematic, authoritative record of horse racing performances. At a time when the sport of harness racing was rapidly growing in popularity across the United States, the publication served as a vital reference for breeders and owners to track bloodlines and official race times, effectively standardizing the industry's disparate record-keeping practices.

The American Trotting Register Association eventually assumed control of the series, continuing the tradition of rigorous documentation that defined the original volumes. Designed as a practical directory rather than a decorative text, the books utilized clean, tabular layouts to manage the immense volume of data required by the racing community. The series is widely regarded by historians of the American equine industry as the primary source for verifying pedigrees and statistical milestones during the foundational era of the sport.
