Robert E. Howard is the world-renowned author of the Conan series and the stories that were the basis of the recent Kull movie. He frequently corresponded with H. P. Lovecraft, and authored many pivotal Mythos tales. This book collects together all of Howard's Mythos tales, including those which originated Gol-Goroth, the Black Book (Unaussprechlichen Kulten), and Friedrich Von Junzt --- all the stories that are usually considered his Cthulhu Mythos yarns, plus another batch that make use of Arthur Machen's lore of the Little People and help fill out the picture implicit in a couple of the over Mythos tales. A third group are tales which Howard did not intend in a Lovecraftian vein but which feature creations later assimilated into the Mythos, whether by Howard, Lovecraft, or later writers. Four Howard fragments are presented here with additional text by yours truly, C. J. Henderson, Joe Pulver, and August Derleth.
