I have learned a ton from reading non-fiction to my boys (including how much I don't know about electricity and chemistry. And isn't it amazing how many new species of dinosaurs have been discovered since I was young back in the 70s? My favorites are an Australian sauropod named Elliot, and the cloying-ly sweet Bambiraptor). But anyway. Today I discovered that adults all over the world have secretly been using quality children's non fiction, with disguised covers, to keep up with the young folks: http://dswindell.members.beeb.net/aFame.htm (still haven't found out how to do nifty links yet).
