The Ultimate Vampire Resource and Directory

Okay, so, I'm trying to write a book that will involve the supernatural, magick, and "fantasy" creatures such as vampires, faeries, werewolves, etc. What I'm asking is if anyone could give me some suggestions of things to look up to involve in the book. Things I've already thought of to include are vampires, werewolves, pixies, faeries, demons, banshees, shape shifters, spelling, scrying, possibly time travel, etc. Please leave a comment or send a message if you have any ideas.
