A peek into the future -- uh, past

A new partnership between Google and Popular Science Magazine has made available the entire 137 year archives of the magazine. Though I'm only a little familiar with the mag, I would imagine there are a number of ways this could be used by instructors. For example: history projects, evolution of technology discussions, changes in writing style over 137 years...and the list could go on. Check it out and relive your great-great-grandfather's youth.
