Whenever I put books on a bookshelf, if the don't fill up the entire shelf, they fall over. I don't have a bookend, and I am lazy and like easy methods. How can I prevent the books from falling over?
I've tried leaning them towards the end of the bookshelf, but somehow the books on the edge still manage to fall over. Perhaps that happens when I take books in and out but don't notice. Anyways, I dislike the look of books when they are tilted; straight vertical looks best IMO.
I've tried putting objects next to the books. This helps, slightly, but the objects I don't mind leaving up there aren't heavy enough, so they slide, then the books fall over.
