Ron,
I have a copy already, I bought it a few years ago, but I still downloaded a copy
from the archive. I can read it better as an e-book. The materials and flies can
be blown up for better viewing. I have copied all of them.
The modern editions are a bit pricey. Your best option is to to do what someone did with the Pritt book, take a CD and get it printed and ring-bound.
