I came across this website the other day. Prepforshtf.com Click the link "free books" and it gives you a nice list of e-books that are free for the day on Amazon. They are kindle format but you don't have to have a kindle. I use an iPad and just had to download the kindle app, works fine. Seems to be a pretty good source of free info on a variety of subjects, prepping, homesteading etc. Its also updated daily! I have no affiliation with this site, just stumbled on to it and thought I'd share.
