Just bought this book
but I have 1, 2 and 3 only from Gould
and 1, 2 and 6 from Tureck
so I need to shop for 4 and 5 to complete my collection.
It's so nice walking with piano music in the morning. I hope I could jog later at which time I'll have to give up listening to piano because the earphone will keep dropping off.
