I'm referring mainly to the authors of these works likely having something lying on a hard drive sitting on a shelf or backed up on 'C: Back up 2012-06-21 4 of 7'. These are much like those piles of old letters found in Grandma's attic, mostly unintelligible (I certainly can't read the cursive scrawls) but still ultimately not 'lost' if someone is prepared to spend the time recovering them.
