quality/condition of the book
The papaer used for the book appears to be very flimsy. The letters are not sharp. I suspect that the book may be the bootlegged version from Taiwan.
However, the subject matter is very good. I actually waited 30 plus years to by both volumes 1 and 2 because they were very expensive then.
Again, I am happy with the content of both books but disappointed about the quality/condition of volume 2.
