It's hard to go wrong heading over to Dean Esmay's place, but this post in particular will be memorable.
Nowadays there's no excuse for letting this living history leave us without documentation. I just lost a WWII veteran a week ago, and one of these days I'll have to debrief a woman who was born in pre-Nazi Germany who *wasn't* Jewish (however unsympathetic they may be, if you think the average German citizen had it easy you're mistaken).
For a taste of a still earlier time there's always the Otto Bettmann classic "The Good Old Days - They were Terrible!", or a number of books by that old lefty Studs Terkel.
