Our own Library of Alexandria is burning as we speak and we
  can't see it. I hate when information is lost. I've been
  watching the streams of information come and gone on the
  Internet since I entered in 1989.

  Where's that message I wrote in 1990 on Usenet? I can still find
  it. Usenet is a distributed network, with multiple copies on
  multiple servers all over the planet. It was designed properly.

  Where's that AOL forum message I wrote in 2002? Wiped in 2007
  when AOL wiped their "Cloud".
  Where's the messages I posted on a BBS in 1995? Only the ones I
  backed up on floppy disk, copied to zip drive, then to an
  external hard drive through the years.

  Now, i go to the library. I see reference books. Books where the
  final copy was published in 2007, 2009, 2011, some as early as
  2003.

  All now online.

  Where will those books be in 100 years?

  The reference pulp paper books might still exist.

  Will the online equivalents be? It's safe to say they won't be
  anywhere.

  That bothers me for the future.
