Books of Blood are a series of horror fiction collections written by the British author Clive Barker. There are six books in total, each simply subtitled Volume 1 through to Volume 6, and were subsequently re-published in two omnibus editions containing three volumes each. Each volume contains four or five stories. The volume 1–3 omnibus was published with a foreword by Barker's fellow Liverpudlian horror writer Ramsey Campbell. For some editions, each book's cover was illustrated by Clive Barker himself.
