No, I'm not talking about The Onion; I'm talking about Weekly World News. The Onion is "America's Finest News Source." WWN is "the World's Only Reliable Newspaper." Get it straight.
Anyway, the good news is, you can now read back issues of WWN's print edition (and several other magazines) on Google Books. The bad news is, the WWN archives only span from January, 1981, to August, 2007. You could go to their web site, but it's just not the same. Call me old-fashioned, but there is a certain charm to the badly Photoshopped black-and-white tabloid layout.
