From the bottom up:
* Stephen Jones (ed.), HP Lovecraft's Book of the Supernatural - Stories Lovecraft mentioned in his essay "Supernatural Horror in Literature". I've read most of these but it's a nice collection.
* Charles Stross, The Jennifer Morgue - Had in paperback, but a read-once Golden Gryphon hardcover with dust jacket for $4 used is hard to ignore.
* Samuel R. Delany, Atlantis: Three Tales - Wesleyan University Press hardcover, and one of his few works of fiction I didn't have.
