I am a bibliophile of the first magnitude. But rather than just reading novels and retrospective history, I love to read ephemera...materials that were of their time.
Anyone with an eye for history these days has an opinion on World War II. But books written DURING World War II to help people do their jobs, know their options and stay safe were amazing. So some of my favourite books from that era were:
Victory Through Air Power - Alexander deSeversky
The Bluejacket's Manual - US Navy
The Punch Below the Belt: Avoid Enemy Suberfuge! - US Army
Education for Death: The Making of a Nazi - Gregor Ziemer
The Boy Scout Handbook - BSA Editorial Staff
You'll notice I did not say "Mein Kampf" by Adolf Hitler. It was maddeningly dense, full of misinformation, and his prose rivaled "It was a dark and stormy night". Same is true about another famous book, "Uncle Tom's Cabin" by Harriet Beecher Stowe.
I also read the Japanese and German surrenders (in full) and various handbooks and instructional films regarding the anti-tank gun, the A-1 Firing Computer and how to operate the flight controls of the B-17 Bomber.
You see, I get a similar feeling inside from reading the exact words and seeing the exact photos and footage that people who fought the war experienced that some pilgrims get when they think they might be standing on the exact spot where Jesus walked on his way to the cross. Nothing that anyone has to say about such things today has the same fresh immediacy of BEING THERE and unlike modern books, ephemera WAS THERE.
One of the most touching moments happened to me when I read in Scientific American about the building of the Brooklyn Bridge. "To people a hundred years from now who read this, our grand technologies will sound quaint and perhaps even humorous." I realized that he was writing TO ME. I was that fellow 100 years from then who read that! Well sir, your grand technologies WERE quaint but I also reached across the centuries as you thought about me and I thought about you, our spirits shook hands and nothing about that was the least bit humorous.
