I guess I should say that its not bad to refer to the books, I mean, that's why they are made, lol. I look at the books a lot b/c I usually find something meaningful in them that I wouldn't have thought of on my own.

But if you were planning on reading for other ppl, you would probably want to develop your intuition enough so you wouldn't have to tell the person to wait while you go look up something, lol.
