Victor Klemperer’s I Will Bear Witness: A Diary of the Nazi Years 1942-45.  He survives.  The diary is gripping reading. He wrote practically every day and gave the pages to a trusted friend.   At the end you get all the daily humiliations, the constant shuffling from hope to despair.  The friends who are shipped away, never to return.  And the constant rumors.  Would it be any different in the Internet age?  A New York Times review is here.   Most complicated.
