There are two ways to approach this topic: to study Satanism as one aspect of various permutations of the occult (which came to prominence during the occult revival in the 1960s) and to study Satanism as a particular path that has adherents and practitioners.
Contrary to popular belief, true Satanism is not specifically the worship of the devil, but rather a set of beliefs related to secular humanism with a dash of hedonism. The beliefs have been set out and detailed in several books by Anton Zsandor LaVey, a self-styled impresario who founded the Church of Satan in 1966 in California. His book 'The Satanic Witch' (Previously titled 'The Compleat Witch') is one book that details the principles of Satanism. He also written a book called 'The Satanic Bible.'
Another fascinating bookon the subject is Dennis Wheatley's 'The Devil and All His Works', which is a study of Satan in literature and history, and also explores the various ways in which Satanism has become a cultural phenomenon.
