What a wonderful gift to anyone in the world interested in science and technology! Popular Science Magazine has teamed up with Google to provide a freely available archive of all 137 years of its publication. Each issue will include its original vintage advertising which will offer even more enjoyment.
I see they also offer a free iPhone app. This is a publication that has obviously embraced the new distribution model offered by online access rather than fritter away valuable time trying to figure out ways to wring the last nickel out of the online public. Kudos to you Popular Science!
