Librarians are very ingenious people.
This is a pretty good disclaimer, as such disclaimers go. I collect intellectual-property disclaimers, and I've seen dozens of them, and this one is at least pretty straightforward. In this narrow and particular case, however, it isn't quite accurate. Bantam Books puts that disclaimer on every book they publish, but Bantam Books does not, in fact, own the electronic rights to this book. Since Bantam has seen fit to peacably agree to this scheme of mine, Bantam Books is not going to fuss about this.
