As for the Weird Tales collection, it's Weird Tales: 32 Unearthed Terrors. It sets out to present the best tale from each year of the magazine's original run. Published in 1988 and edited by Stefan R. Dziemianowicz (as if the eldritch gods didn't inject enough unpronounceable names into the mix) you've got everyone from Isaac Asimov to Seabury Quinn to good ol' HPL himself with "The Case of Charles Dexter Ward"

Not quite the $1 deal I got from the library sale, but not as outrageous as some of the out of print prices on Amazon.

Came here to mention Clive Barker, Books of Blood is the way to go

I enjoy Clive Barker's books. The Hellbound Heart is the basis for the Hellraiser films. There are so many to list but off the top of my head The Great and Secret Show, The Books of Blood, The Damnation Game, and Weaveworld are all great stories. The Thief of Always, while a childrens book, is also a good read. Enjoy and good luck

Barker's [Books of Blood.] (http://www.amazon.com/gp/product/0425165582/) I think it's volume three that has a story called "Son of Celluloid." First Barker I ever read and it's pretty awesome. If you can find it they once made a comic of it, too. Kind of cool.

Looking Good baby!!
Here is one of my all-time favorite books! Pretty interesting if you like books made out of human skin!

Does your friend like specific types of horror or does he just love every aspect of the genre?

Without knowing any specifics, here are a couple of things I would recommend anyway:
http://www.amazon.com/Books-Blood-Vols-Clive-Barker/dp/0425165582 Some of the best horror short stories writen.
