Stanley Wiater's "Modern Horror Fiction: 113 Best Books"
From Stanley Wiater’s book Dark Thoughts on Writing (http://www.allconsuming.net/item/view/1227949 ). In the reference section at the back is this list of books by horror, dark fantasy, or dark suspense authors who have "received critical success or awards in his or her career." Wiater’s list includes "styles ranging from the most repulsively explicit to the most maddeningly subtle."
"Modern" here means published after 1960 (but before 1997, when the book was published.)
The list is alphabetical by author.
