The Onion
Since the first publication of "Our Dumb Century" in 1999, "The Onion" has produced various books that often compile already produced material into collected volumes. The 2007 publication of "Our Dumb World" and the 2012 publication of "The Onion Book Of Known Knowledge" are the only other fully original books content-wise—other than "Our Dumb Century"—that "The Onion" has released.
