Here are a couple books I can recommend:
From the Beast to the Blonde: On Fairy Tales and Their Tellers by Marina Warner
No Go, the Bogeyman: Scaring, Lulling, and Making Mock by Marina Warner
Breaking the Magic Spell: Radical Theories of Folk and Fairy Tales by Jack Zipes
There are a lot of good articles on the archive for The Journal of Mythic Arts.
The articles usually cite a number of books for further reading.
