This book is out of print and from reading other threads, I've deduced that John Burke is still around...
The cost of the book is out of control. Would someone be willing to make a PDF of it available? I'm guessing that getting in contact with John Burke would shed some light on the legality.
I want it so bad but cannot pitch $130! Maybe it could go up on a for donation basis with the donations going to John and family?
