There’s a lot of people angsting about piracy and copying of stuff on the Internet, publishers who are very, very worried about the whole idea of ebook piracy. I like to get a little bit of perspective on it by remembering that back before the Internet came along, we had a very special term for the people who buy a single copy of a book and then allow all their friends to read it for free. We called them librarians.
