I’ve been thinking that it might be useful to have some books stored on my kindle in case of being in a situation where we’d need to be more self sufficient. Wouldn’t necessarily read them all now, more just have them stored in case they are needed. Thought it would be a good way to store info and could use a small solar charger in case of power outages. Does anyone’s have any recommendations? I’m thinking along the lines of growing food and self sufficiency, maybe something medical, other useful skills? What do you reckon?
