That Dewey and His Decimal System
Who knew that the Dewy Decimal system was copyrighted? Not I. Neither did I know that there is a hotel in New York that uses the DDS to organize it's rooms, at least not until I read about it on Neil Gaiman's journal. Of course, they're being sued for copyright violation because, as we all know, if just anybody were to start using the DDS, civilization as we know it would crumble. But the remains would be very well organized.
