Any good books with information on Faeries and Faery Folklore?

I've been reading the Iron Queen by Julie Kagawa and it has really sparked my interest in faeries. I want to learn more about them. I want to learn more about the seelie and unseelie courts, Oberon, Titania, Puck, and other faeries like bogeys and brownies. I've heard of Brian Froud's Faeries and his other book Good Faeries and Bad Faeries. But I am still undecided. Maybe you can give me more recommendations and tell me if these books are good for information.
