This is one thick book, but very lightweight. The Complete Chronicles of Conan: Centenary Edition is a collection of fantasy short stories written by Robert E. Howard featuring his sword and sorcery hero Conan the Barbarian.
The book was published in 2006 by Gollancz and is an omnibus of their earlier collections The Conan Chronicles, Volume 1: The People of the Black Circle and The Conan Chronicles, Volume 2: The Hour of the Dragon, though the stories are rearranged. The collection is edited by Stephen Jones and was issued to celebrate the centenary of Howard’s birth. Most of the stories originally appeared in the magazines The Phantagraph, Weird Tales, Super-Science Fiction, Magazine of Horror, Fantasy Fiction, Fantasy Magazine and The Howard Collector.
