Thanks for the replies. I haven't been having luck with a few sheet music viewing apps I've purchased like ForScore. I go to their darkroom section where I'm supposed to take pics with my new iPad (3). I do but then I can't get the orientation to stop rotating the wrong way. I'm going to try UnReal book (never heard of it before).
I have a new 2012 book called MAKE MUSIC WITH YOUR iPAD.
