Just a quick link today because I'm about to sit down to work.
Folktext - a library of folktales, folk lore, fairy tales, and mythology.
It's alphabetical, so easy enough to search through. It's also fun to just browse down the links and read what sparks you. Story ideas aplenty in there, and if you've already got an idea in mind along those lines, it can provide some good information.
I haven't clicked very many places in there, so as always, surf at your own risk.
