encyclopedia

In 1408, an encyclopedia containing nearly one million pages was finished. Called the “永樂大典”, which translates to “The Great Canon of the Yongle Era”; today it’s just, in English, the “Yongle Encyclopedia.” It was commissioned by Emperor Yongle (surprise!) of the Ming Dynasty.  It held the record for the largest overall encyclopedia in the history of the world until September 9, 2007 when Wikipedia surpassed it.
