The Belgariad
Steve Pemberton's "The Times &amp; Life of Lucifer Jones" describes the distinction thus: "The difference between a wizard and a sorcerer is comparable to that between, say, a lion and a tiger, but wizards are acutely status-conscious, and to them, it's more like the difference between a lion and a dead kitten." In David Eddings's "The Belgariad" and "The Malloreon" series, several protagonists refer to their abilities powered by sheer will as "sorcery" and look down on the term "magician", which specifically refers to summoners of demonic agents.
