This book-collection file includes: A Princess of Mars, 1912 (the book that the movie "John Carter" was based on); The Gods of Mars, 1914; The Warlord of Mars, 1918; Thuvia, Maid of Mars, 1920; and The Chessmen of Mars, all of which are in the "Barsoom" series. According to Wikipedia: "Edgar Rice Burroughs (September 1, 1875 – March 19, 1950) was an American author, best known for his creation of the jungle hero Tarzan and the heroic John Carter, although he produced works in many genres." Also according to Wikipedia: "Barsoom is a fictional version of the planet Mars invented by author Edgar Rice Burroughs for a series of action adventure stories. In 1911, Burroughs, now better known as the creator of the character Tarzan, began his writing career with A Princess of Mars, a rousing tale of pulp adventure set on the planet. Several sequels followed, filling out his vision of Barsoom and developing it in more detail. A Princess of Mars was possibly the first fiction of the 20th century to feature a constructed language; although Barsoomian was not particularly developed, it did add verisimilitude to the narrative."
