During Wright's editorship of "Weird Tales", which lasted until 1940, the magazine regularly published the notable authors H. P. Lovecraft, Robert E. Howard and Clark Ashton Smith. Yet Wright had a strained relationship with all three writers, rejecting major works by them — such as Lovecraft's "At the Mountains of Madness" and "The Shadow Over Innsmouth", Howard's "The Frost Giant's Daughter," and Smith's "The Seven Geases" (which Wright dismissed as just "one geas after another"). He could be both discouraging and encouraging with equal lack of logic. His preference for shorter fiction particularly led him to discourage Lovecraft's, whose best works emerged at longer lengths during the early 1930s. Nevertheless, as Mike Ashley has put it, "Wright developed "WT" from a relatively routine horror pulp magazine to create what has become a legend."
