I just discovered that Popular Science has partnered with Google Books to provide access to all the old issues of Popular Science and made them available for FREE right here:

You can search for specific phrases like "Tesla" or "high voltage", but I find it's actually much more interesting to just pick an old issue and scroll through it page by page.  The pictures are fascinating and some of the classic language is awesome.  Case in point, "The rowboat bath is the newest contribution to the physical enjoyment of living" (Popular Science Monthly, April 1916, Vol. 88, No. 4, pg. 486)
