King Conan is the fourth published and contains several Howard stories (see notes and contents).
The Gnome Press edition of Conan was the first hardcover collection of Howard’s Conan stories, including all the original Howard material known to exist at the time, some left unpublished in his lifetime. Not published in order of previous publication, Gnome’s volumes were organized to present the stories in order of their internal chronology, the sole exception being Tales of Conan, which skipped around to present random episodes from various points in the protagonist’s career. Some stories in two of the later volumes (The Coming of Conan and King Conan) were completed or revised by L. Sprague de Camp; another (Tales of Conan) consisted of non-Conan Howard stories that de Camp rewrote as Conan yarns. The last published volume of the Gnome edition was the first Conan story by an author other than Howard, namely Björn Nyberg, and was revised by de Camp.
