Klamath - I went onto that site and it is demented! I had never heard of these books before. Many of them seem to end up with the child dying for a naughty thing they had done. Right up there with the Brothers Grimm. *shiver at the thought*. I also found Alice in Wonderful really scary growing up and I still do.
Even Rat's books will never beat Der Struwwelpeter, the most nightmarish children's book of all. http://en.wikipedia.org/wiki/Struwwelpeter. My German uncle has this book; it's truly something I would NEVER show to kids.
