This is the best book in my equine library. It it the only book I have found which contains good information about little known breeds, such as the Asturian, Lewitzer, Pinzgauer, and Moyle Horse. Each desciption is well-researched and contains a great deal of information about that breed's origin, conformation, population, and common usage. If you show model horses, it is an invaluable guide for breed assignment; how else would you know that your San Domingo makes a perfect Wielkopolski, or that your standing Thoroughbred Mare is an ideal Cirit horse? The only thing that would make this book better would be color photos, but that would most likely make it prohibitively expensive.
