When you loan out a book, it's with the idea that the person you are loaning it to will enjoy it. However, there's another unwritten expectation—that they'll also take care of it! it can be pretty devastating when you get a book back that you loaned to someone and have the spine be decimated, or the pages dog-eared. So, before that happens—or because it's happened one too many times—do you have any rules for people who borrow your book? What are they? Do you have a “blacklist” of people who are not allowed to borrow books from you any more?
