Ok, in hard back, there is an Icewind Dale Trilogy, A Dark Elf Trilogy, and a Legacy of the Drow Collectors Edition. There is a Cleric Quintet thing Salvatore did, but it doesn't focus on Drizz't. He wrote them in the above order, but I would recommend reading them in Chronological order, ie The Dark Elf Trilogy, Icewind Dale, then the Legacy of the Drow. All in Hardback, mind you. Each Hardback has three or four paperbacks in it. Makes it almost worth the $25 for each. Which reminds me. I need to go by the Legacy one. It is newish.
