A lot of good ideas above. I will just add that Little Free Libraries are an ideal way to get rid of books a little bit at a time, gradually, so that you don't end up having a whole bunch of books that you need to find a home for. Back before the Little Free Libraries came along, I had to have a troop of Boy Scouts tote hundreds of my books to a library booksale; the poor boys were exhausted by the end. But these days, when I go out, I take a book or two with me to drop off at a Little Free Library. And the books always end up disappearing from the Little Free Library box, so I know that somebody appreciated my donations.
