Weird West Reading List

This is a fairly new subcategory of fantasy and so doesn't have a large number of books yet, but I figured for those of you looking for more, a list might be useful.  This list is made up from books in stock at the bookstore where I work, plus any I heard about from internet sources.  If you know others that should be on this list, please mention them in the comment section and I'll add them in.

This particular list is a mix of horror and SF/fantasy books.  I tried to keep it to books with cowboy like figures or with a western feel to the story, so no civil war or depression era stuff.
