Hi everyone
I have bought this book recently
http://www.abebooks.com/P.A.D-Power-Anc ... 2463337/bd
It's a simple little book, and at first glance, it seems similar to NAP in the approach (I might be wrong as I just browsed it superficially so far)
I searched for "BOTTOMLEY" on the forum and found some comments about other books, but not much about PAD.
If anyone has comments or advises, thanks in advance for sharing,
Cheers !!!
