Below is an alphabetical list of Lovecraft’s fiction, revisions, collaborations, and miscellaneous minor works, as well as some tales that are not extant. The dates for each of the tales are based primarily on S.T. Joshi’s “Chronology of the Fiction of H. P. Lovecraft” included in Arkham House’s Dagon and Other Macabre Tales, but includes some changes based on Mr. Joshi’s ongoing research. This list is also available in both chronological order and publication order.
