Reddit reviews The Best of David Bowie: 1969/1974- Piano / Vocal / Guitar

I once had a piano book of Bowie songs that looked like the 'Best of Bowie year-year'. It's written as sheet music.

Also useful and well organized for learning Bowie songs, but mostly chords and guitar tabs: lovebolts

This is the best book from the published ones I've checked out. It doesn't have every song from Ziggy but it does have a lot of other songs from that era, including Life on Mars and Aladdin Sane.
