You sould read IT by stephen king. Its one of his best books.

Or you could read The Exorcist, it's pretty kool

Peacable Kingdom by Jack Ketchum is one of the best collections of psychological horror that I've ever read, and I'm not really a fan of short stories. The Books Of Blood by Clive Barker is priority.

I think some of the Best New Horror series has some awesome stories in it.Edited by Stephen Jones,they contain some of the best stories ive ever read.Also "Dark Forces" edited by Kirby McCauley,which includes the Stephen King masterpiece"The Mist".also..as far as collections by individual author.'s I'd reccomend the Books of Blood series.Lovecraft collections,and Stephen Kings Night Shift,Skeleton Crew ,and Nightmares and Dreamscapes ..as well as Bently Littles "The Collection"..Robert R McCammon's Blue World,and Dean Koontz,"Strange Highways".

try to locate some Harlen Ellison.
most of his work is short story.

I have some free shit on my site at www.joeknetter.com
I have 2 books coming out soon. Twisted Loneliness and Zombie Bukkake. It's nasty but fun.

I don't often read short stories for the simple reason that you have hardly began reading when you in the midst of mayhem...
i like a story to take it's time, so novels are superior...do you guys agree?
Anway...
The collection of short stories by Stephen king (aka Richard Bachman) are cool.

Some of my favorites:

999
October Dreams: A Celebration of Halloween
The Dark Descent: I haven't read this yet, but it contains TONS of classic horror stories from all of the masters of the genre, including Poe, Lovecraft, M. R. James, King, Barker, Shirley Jackson, Algernon Blackwood, Nathaniel Hawthorne, Ambrose Bierce, and many, many more. I can't recommend this one highly enough!
The Mammoth Book of Best New Horror Series, now in its 15th year
Tales of the Cthulhu Mythos
Gathering The Bones

As far as short story collections, nothing beats Everything's Eventual by Stephen King. King's the MAN, I don't care what anyone says.

i recomend wheres walddo? its horrifying.
