What site can i find the real cinderella, snow white, etc. stories?

I don't remember off hand who wrote the stories but Cinderella's stepsisters did cut off parts of their foot to try on the slipper. But as for the cheating prince the story always ended when they got married and lived happily ever after. Another one is Little Red Riding Hood, many stories and rhymes were changed over the years because children would get scared. Three little pigs.
