Just one thing to post this week, and that's Picture History. It is certainly cool enough to warrent a post of it's own.
"We have compiled a collection of thousands of the most important photographs of the last 150 years; pictures of our struggles, trials, and triumphs. We can only fully understand our history by gazing into the eyes of the people that made that history. Their eyes will tell a story that no words can. Browse the images by Theme, or use the search tool to find a picture or period of interest."
