"Popular Science" magazine archive now online for free

It looks like Popular Science and Google have teamed up to provide its entire archive online for free. The link below will direct you to the search page. Just enter something into the search box and a list of potential matches will be displayed. There are some drawbacks: Entire separate issues cannot be viewed and the article or sections of an article cannot be copied. That's not good, but at least they are available to read including any advertising.
