"If every download replaced a sale, there would be no commercial music industry left. The relationship between the free version and the legitimate version is rather complex, like the relationship between a public library and a book publisher. Sometimes free stuff sells stuff."
"In the digital realm, however, copyright holders may install digital-rights-management schemes that limit the transportation of both the container and the content.

As a result, libraries of the future could be less useful to citizens."
