I'm currently working on an urban fantasy story and am having difficulty in finding more obscure monsters and legends to draw from. Most of what I know stems from basic Arthurian, Greek, and Tolkien mythos. I've always been impressed by the diversity of the mythologies that authors, such as Michael Mignola and Jim Butcher, cite in their works. Unfortunately I have no idea where to look to find more about these diverse legends. If anyone knows of any reference books or websites that provide information on other mythologies the help would be greatly appreciated.
