Delirium Books, launched in the summer of 1999 by Shane Ryan Staley, was a horror publisher in the collector's market, producing low print-run limited editions intended for collectors and readers alike. Limited-edition books published by Delirium were reputed to sell out quickly, making their publications highly collectable. Delirium Books published The Rising, the first book in a series of zombie-themed horror novels written by Brian Keene, which won the Bram Stoker Award for Best First Novel in 2003. In 2005, Delirium Books won the Bram Stoker Award for Excellence in Specialty Press Publishing, presented by the Horror Writers Association (HWA). The same year, Delirium took home the first annual Shocker Award for Small Press of the Year, presented by Shocklines.com. Per Staley, Delirium Books ceased activities in January 2013.
