Chances are you don’t know everything there is to know to thrive in an emergency or SHTF scenario. There is also not enough time in the day to read and practice the things that we would need to know if things went awry. Having the right books on hand, paper and digital to supplement your existing knowledge and skills will be crucial, and I fear often over missed. I use Amazon and buy only Used books. This way I get them cheap AND if the book wasn’t what I was expecting I can simply return it in most cases.
