Just got a free Nook from a neighbor, thinking about what I should put on it. I don't feel like spending a ton of money on digital books, so I'll be uploading PDF's. Planning on having a whole survival/prep library of different things, plus all my favorite novels. Lord of the Rings Trilogy will keep me busy if I'm ever stuck somewhere and bored. Easier to carry the Nook in my bag, even though I love paper books. Any suggestions or tips for a new Nook user?
