Legends, Volume 4 carries on the tradition of its predecessors, profiling great horses who have significantly influenced the Quarter Horse breed. Four mares and 13 stallions comprise this volume, which includes both tales that predate the 1940 formation of the American Quarter Horse Association, and contemporary stories whose ultimate conclusions may not be known for years to come.

Each chapter is devoted to a specific stallion or mare, and includes a four-generation pedigree, a summary of the horse's performance accomplishments, a sire or production record, and several photographs. Yet what sets the Legends books apart from pure pedigree research is the personal information and commentary from the people involved with each horse--the people stories behind the horse tales.
