The Library Catalog is the best place to start. You can find fairy tales, their adaptations and retellings, biographical information about the authors (when known), and scholarship about the fairy tales, themes, and creators. Note: Fairy Tales are located in various library locations, such as the CMC (Curriculum Materials Center). Each record notes the location and has a Map It link to show you where to find the book.
