[Breza]

I disagree strongly with your broader point. We now have the technology to sort through the minutia of the past and learn deep things. Here's one tiny example. I was able to find out where one of my ancestors lived because someone sent him a letter via General Delivery around 1900 that he didn't pick up. The Post Office listed everyone with letters waiting for them. The smallest detail, but it proved useful for me in tracing my family's origins across the Wild West.
