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]
