People worry about that shit too much... nothing wrong with reading & gathering information. These books are all sold legaly in certain bookstores and army surplus stores. Available to purchase online as well.
Guess it all depends on the person and his intended use of said material.
Very interesting reads none the less. And that's obly a fraction Of my EDC books contained in my phone, i pads and computer.
So I take it most people around here don't edc any kind of books in electronic format?
I believe in real money and edc books on coins / metal. I also have knot tying and rigging manuals on my phone. I have the kindle app on my phone and downloaded the Art of War and a few other free titles.
