The book "John Carter of Mars" comprises two novelettes originally published in Amazing Stories pulp magazine: "John Carter and the Giant of Mars" was published in the January 1941 issue with the byline "Edgar Rice Burroughs". However, ERB had nothing to do with the writing of the story! It was written by his younger son, John Coleman Burroughs. In the February 1943 issue of Amazing Stories, "Skeleton Men of Jupiter" appeared, the first part of a 4-part novel. Unfortunately, due to World War II and the failing health of ERB, the remaining 3 stories were not written.
