Over at The Vault of Horror, they have a series on the folklore behind Halloween's scariest goblins, traditions, and trappings. And Jeanette Laredo of the blog Monsterland contributed an essay on some of the folktales around that world that feature the Headless Horseman. It's a great, enlightening read for those of you who believe that a decapitated spirit of vengeance began with the famous tale by Washington Irving.
You can find the remaining posts here. One of them, about the Jack O'Lantern, is my own humble offering. Brian Solomon, or "B-Sol," is the tireless curator of The Vault, and it is one of my favorite places on the internet. Of course, if you've seen the sick sh-t I like, you'd reconsider taking advice from me. But don't let my Brady Bunch-themed hentai fetish sour you on B-Sol! He's a decent egg. Whatever twisted obsessions haunt him, clearly he's using them for good.
