The Horror in the Museum and Other Revisions is a collection of stories revised or ghostwritten by American author H. P. Lovecraft. It was originally published in 1970 by Arkham House in an edition of 4,058 copies. The dustjacket of the first edition features art by Gahan Wilson. The collection was revised in 1989 by S. T. Joshi adding an introduction by Joshi, correcting the texts and expanding the contents. In 2007, Del Rey published a trade paperback version with a new introduction by Stephen Jones, and a brief biography of Lovecraft at the end. The revised version of Lovecraft's revisions includes Henry S. Whitehead's "The Trap" but not the other two stories by Whitehead in which Lovecraft had a hand ("Cassius" and "Bothon"). The revised version also includes two collaborations by Lovecraft with Robert H. Barlow, but not the other tales on which they worked together, of which there are four or five. Sonia Greene's "Four O'Clock" is omitted from the revised version, S.T. Joshi having determined that this tale is not properly a part of the Lovecraft corpus; the story is entirely Sonia's, Lovecraft having simply made a few suggestions as to its prose style.
