As a writer, this really scares me: the possibility that a simple flicker of electricity could wipe out -- forever -- important works that only exist in a digital realm.
Recently, I finished digitizing 30 years of newspaper and magazine articles that I wrote (but not all of them, of course), 10 years of radio documentaries, and miscellaneous other bits and pieces of my writing work.
Every month, I do a data backup of these and other important files so I won't lose them.
It seems, however, that the same issues that are the concern of my little world are being played out by important institutions responsible for important works. Now, that is scary.
