I am currently reading a book titled "A Witch's Guide to Faery Folk" by Edain McCoy. I have read the first 3 chapters and like it quite a bit. It has an introduction to Faeries and 3 main sections: (1) All About the Little People; (2) Working with Faery Beings; and (3) A dictionary of Faery Folk of the World (230 Faeries!). If you own the Fairy Ring Oracle you will definetly want this book.
