Lovecraft 101

Hey there, I never read Lovecraft before, and I want to know what some of his best/most popular work is. Specifically, I'm more interested in the psychological/driven insane stories rather than the monster stuff.

well, now I feel pretty dumb for not checking out Wikisource

http://en.wikisource.org/wiki/Author:H._P._Lovecraft

Any particular selections from this list I should check into?

also, do the text boards always get this much spam?
