Shanghai Library
Several versions of the expanded "Sanguozhi" are extant today. Luo Guanzhong's version in 24 volumes, known as the "Sanguozhi Tongsu Yanyi", is now held in the Shanghai Library in China, Tenri Central Library in Japan, and several other major libraries. Various 10-volume, 12-volume and 20-volume recensions of Luo's text, made between 1522 and 1690, are also held at libraries around the world. However, the standard text familiar to general readers is a recension by Mao Lun and his son Mao Zonggang.
