The Press of James A. Decker was a poetry publishing house once located in the tiny hamlet of Prairie City, Illinois. The Decker Press received national attention in the 1940s, when it published work by famous authors like Edgar Lee Masters, August Derleth, Hubert Creekmore, William Everson (Brother Antoninus), David Ignatow, Kenneth Patchen, Kenneth Rexroth and Louis Zukofsky.
The Archives and Special Collections Unit at Western Illinois University Libraries is the single-largest holder of materials from the Press of James A. Decker. Archives staff has compiled a complete bibliography of Decker Press books with a listing of which books are currently held there. Other materials include unpublished typescripts about the Decker Press and James Decker, correspondence, newspaper clippings, and historical articles.
