Those who recognize that the original Tarzan is a literary creation of Edgar Rice Burroughs understand that the exploits of Tarzan are best explored through the magical medium of the printed word. Readers can experience a journey that lasts through 24 books and wanders not only into the jungle depths but farther down through the Earth's crust into the savage prehistoric land of Pellucidar. Also covered is the long out of print The Tarzan Twins as well as the recent Tarzan, the Lost Adventure and The Eternal Savage.

This book serves as a literary guide to all the Tarzan novels. Section One provides an overview of Tarzan the character, including a list of the many names and titles used by and given to Tarzan; Section Two covers the mythical language used in the novels, including a dictionary of the ape language; Section Three enumerates the lost cities, civilizations, tribes, peoples and religions discovered by Tarzan, detailing their religious rites and locations; Section Four describes the characters (human and otherwise) found in the novels; and Section Five gives summaries of all 24 books that comprise the Burroughs canon. The book also includes over thirty illustrations from the series' various printings.
