A unique feature of this book is the accuracy of the Type descriptions. The data for these descriptions was collected over a period of more than fifteen years, and came from people describing their own Type in detail. The information was all new information and is presented in this book as it was expressed by the contributors. The result is accurate descriptions that immediately resonate with the reader when they read their own Type description. Since publication in 2004 this book has sold more than 120,000 copies
