Big Planet is a science fiction novel by American writer Jack Vance. It is the first novel (the other being Showboat World) sharing the same setting, an immense, but metal-poor and backward world called Big Planet. Big Planet was first published in Startling Stories (vol. 27 no. 2, September 1952), then cut and reissued in 1957 by Avalon Books. It was later issued as part of Ace double novel D-295, paired with Vance's Slaves of the Klau. It was further cut in 1958. The text was restored in 1978. Source: Wikipedia (en)
