The Land that Time Forgot

The Land That Time Forgot is an Edgar Rice Burroughs science fiction novel, the first of his Caspak trilogy. His working title for the story was "The Lost U-Boat." The sequence was first published in Blue Book Magazine as a three-part serial in the issues for September, October and November 1918. The complete trilogy was later combined for publication in book form under the title of the first part by A. C. McClurg in June, 1924. Beginning with the Ace Books editions of the 1960s, the three segments have usually been issued as separate short novels. The first of these is treated in this article.
