If you are going to be moving around a lot, you could pick up books at the local booksale, rummage sale, Goodwill, etc, and leave them behind as you go. If you are going to be staying in one place, you probably can't get a library card, but find the local Goodwill and buy books that you can, again, leave behind or re-donate. If you are flying, and going through Milwaukee, there is a used book store in the airport terminal! Stellar idea!
