I found this in the newsletter put out by Librarians' Internet Index.
"Collection of horror fiction reading lists for adults and teens. Topics include vampires werewolves, zombies, horror-themed romance, and more. Also includes suggestions for scary books for children, and reviews of horror podcasts"

From the Monster Librarian Website. "The Monster Librarian welcomes you! This site is dedicated to all the books that are creepy, scary, and give us the willies. It is meant to be a resource for readers and librarians. For readers of horror, this is designed to be a site where you can find other books that fall into the horror category that you might be interested in reading. For librarians, this site provides tools to help in collection development, readers advisory, and program planning. While the site will have information on current mainstream horror it will also include in the various lists older books that may be of interest."
This looks to be a fairly new site but has a very enthusiastic staff. There is also a Monster Librarian blog that seems promising.
