This volume collects H.P. Lovecraft's three major works on fantasy fiction: "Supernatural Horror in Literature" -- his survey of the weird and supernatural in fiction; and "Notes on Writing Weird Fiction" and "Notes on Writing Interplanetary Fiction" -- his how-to essays on crafting solid, aesthetically pleasing works in those genres. An essential volume for scholars, writers, and those interesting in the history and craftsmanship of the fantasy genre.
