This morning I looked through my list of the books in my own “prepping library” to see which ones I have in physical form and which in digital form. I made a note of which ones I want to be sure to have in “hard copy” in case there is no electrical (or battery) power to run my laptop or e-reader. I also wrote down which new books I’d like to get to fill in the gaps in my library. Then I downloaded back-up copies of my digital format prepping-related books onto 2 sets of flash drives (gotta have a back-up to the back-up after all, LOL).
