Delirium Books, launched in the Summer of 1999 by Shane Ryan Staley, is recognized as one of the premiere horror publishers in the collector's market, producing low print run limited editions intended for both collectors and readers alike. Delirium Books first published The Rising, the first book in a series of zombie-themed horror novels written by author Brian Keene, winning the Bram Stoker Award for Best First Novel in 2003 and helping ushering in the new era of zombie popularity in mid-2000s.
In 2005, Delirium Books won the prestigious Bram Stoker Award for Excellence in Specialty Press Publishing, presented by the HWA (Horror Writer's Association). The same year, Delirium took home the first annual Shocker Award for Small Press of the Year, presented by Shocklines.com, one of the biggest independent horror booksellers in the U.S.
Some of the first offerings from Delirium Books were magazines, all digest-sized with color covers. The print runs for these magazines is unknown.
Delirium's Hardcover Line features first edition titles produced in limited editions with full-color dust jackets. Delirium produces true limited edition hardcovers, as the runs in this line are signed and numbered from less than 50 to 500 copies. The first five Hardcover Line books were released without dust jackets. Beginning September 2008 the Hardcover Line is published as a subscription at 150-copies and is sold-out pre-publication.
Genuine leather books housed in an equally attractive genuine leather hinged box, the Ultra Series offers the collector's community extremely rare editions by some of the biggest authors in the genre. Buyers have the option to personalize their copies by getting their names on a special "thanks" page from the author, as well as having their book personally inscribed. Produced in an extremely limited nature, only 26-36 copies produced of each title.
This special series focuses on titles that have never before seen print as a hardcover. Delirium Books reprints these Horror Essentials for collectors who prefer hardcovers in their personal libraries. In each limited edition hardcover, Delirium includes special original bonus material not found in the original paperbacks. Each book is signed by the author and limited to no more than 200 copies.
At the end of each year, Delirium will offer custom-made slipcases to house the entire volume of books. This special slipcase features the Dark Essentials logo as well as the volume lineup.
