This is a link to the Sur La Lune fairy tale site. I haven't been in there in a while, and it has grown tremendously. There's a great deal of full text, classic traditional folk tales of a lot of traditions, not just Irish and Celtic, but also Nordic (which is related), eastern European, Canadian, Japanese, you name it. Stuff that is out of print and that you'd have to look all over the net to find. There's also some classic texts of scholarship and essays about fairy and folk tales too. It's just a great resource.
