[D]on't ever apologize to an author for buying something in paperback, or taking it out from a library (that's what they're there for. Use your library). Don't apologize to this author for buying books second hand, or getting them from bookcrossing or borrowing a friend's copy. What's important to me is that people read the books and enjoy them, and that, at some point in there, the book was bought by someone. And that people who like things, tell other people. The most important thing is that people read.
