Billy Joel/Elton John fans please help! I'm looking for the real piano sheet music. Please please help!?

I did find The Billy Joel Keyboard Book: Note-for-Note Keyboard Transcriptions and the same book for Elton John on amazon.com, but they're missing some of my favorite songs!!!!! Is there another book? If so, where can I find it? Please please help!!! I will be SO greatful! I'll choose a best answer and what not, and as soon as I can all give all your answers huge thumbs up! This is really important to me (way to go captain obvious, right?). Thanks a bunch!!! :) :) :)
