Clark Ashton Smith was one of the earliest writers to produce Sword & Sorcery stories. He set stories in the imaginative lands of Averoigne, Hyperborea, Zothique and Poseidonas. Like many early S&S stories, his were a melange, often containing and combining Lost World, Dying World, SF, Horror and Fantasy elements. Until comparatively recently, I didn't know much about his work and had read none of it. It doesn't seem to be widely available in print anymore. Fortunately, for those who are curious about his writing and for long standing fans, there is an authorized website that contains a large number of his works. The site is The Eldritch Dark. A list of his stories that most resemble S&S (according to the website's author) can be found here. Click on the links and enter the realms of CAS.
