I have an extensive library of survival and prepping type books, I don't file anything on my computer as I wont be able to charge it post SHTF, I prefer actual books anyway and these will be usable long after any ebook has gone the way of the dinosaurs.That's where I'm going too, if we are off grid, can't charge the laptops and read all of the e-books I have downloaded, then only paper is real. I have enough for me and the wife, the kids don't prep yet. If I gotta support them, it might get tight after about a 3-4 month period. Been prepping long, but don't have the money for sooo much yet either. Won't be bartering too soon except for knowledge, maybe I could get a few things in payment for a survival class. Need to think about this...GP
