Old Book of Tang

The Old Book of Tang, or simply the Book of Tang, is the first classic historical work about the Tang dynasty, comprising 200 chapters, and is one of the Twenty-Four Histories. Originally compiled during the Five Dynasties and Ten Kingdoms period (10th century AD), it was superseded by the New Book of Tang, which was compiled in the Song dynasty, but later regained acceptance. The credited editor was chief minister Liu Xu, but the bulk (if not all) of the editing work was actually completed by his predecessor Zhao Ying. The authors include Zhang Zhao, Jia Wei (賈緯), and Zhao Xi (趙熙).
