The hardcopy is printed on tear-resistant, water-resistant, synthetic paper. A 5.25 inch by 8.5 inch quick-reference guide with a three hole punched ring binding for $59.00 from the U.S. Government Publishing Office .
Beware of the very early versions (pre 2000) as they truly outdated.
I also keep a copy around of Ditch Medicine, it’s a good reference. It’s actually the only one that I have in my med bag right now. I need to get another copy of SF Med handbook and Where there is no doc.
