From the vaults of The SF Gateway, the most comprehensive digital library of classic SFF titles ever assembled, comes an ideal introduction to the fantastic worlds of one of the greatest adventure writers of all time, Edgar Rice Burroughs.

The son of a Civil War veteran, Edgar Rice Burroughs was a prolific writer for the early pulp magazines. Famous the world over as the creator of Tarzan - and in SF circles for his Martian tales featuring John Carter - Burroughs is a household name. But there was more to him than apemen and four-armed Martians! This omnibus collects his tales of the world within a hollow Earth: At the Earth's Core, Pellucidar and Tanar of Pellucidar.
