"Tarzan of the Apes" first appeared, complete, in the October 1912 issue of The All-Story pulp magazine. In June 1914, the first hardcover edition was published by A. C. McClurg and Company. Between these two appearances of the story, the author, Edgar Rice Burroughs, modified the original magazine text because of an error in it (he included tigers in Africa!). While fixing this error, he polished/rewrote portions of the story, finishing with an additional 2,000 words of text.
In July 1963, Ballantine Books published the story in paperback. In their fourth printing in August 1966, they began editing and abridging the text. In the fifth printing in April 1969, they censored the text. In August 1993, Gutenberg.org uploaded an electronic text based on this fifth printing--the censored, edited, and abridged version.
This book compares the two texts, First Edition and Gutenberg, side-by-side, for scholars and laymen to see the alterations the editors at Ballantine Books performed on the text.
