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]

Pre-WWW but it communicates over TCP/IP]
