Apparently he expanded one, "The Phoenix on the Sword", into a novel, because the story has part of the same introduction the novel had, and a few of the details in the story are the same as the novel was, though in the book length they are highly rearranged, with many substitutions of events. The collection's introduction says the story went through some revisions even as a story, and at the end of the collection the original unpublished story is printed. The introduction is the one that begins, "Know, oh Prince.." I think De Camp's complaint when he said the works of Howard were not available was that they had not been published in book form, but since that time his writings have been getting published. His stories were in Weird Tales more than anywhere else.
