There's a whole WORLD that's _everything_ to librarians but is
   hardly known outside of their world. I know about them because
   I... um... yeah I err.. hacked it a little. I got my name in a
   handful of their databases with fake books year year during a
   bored night utilizing ancient protocols that few even know
   about. I hoped it would spread virally, making me an author
   showing up in libraries everywhere, but it only seemed to affect
   a few libraries and then vanished after a week. Meh. [ps - it's
   this protocol: [1]https://en.wikipedia.org/wiki/Z39.50 - it's
   Pre-WWW but it communicates over TCP/IP]
