Beginning in the Northern and Southern dynasties (420589) and the Tang dynasty (618907), a number of scholars wrote and edited commentaries to the "Records". Most 2nd-millennium editions of the "Records" include the commentaries of Pei Yin (, 5th century), Sima Zhen (early 8th century), and Zhang Shoujie (, early 8th century). The combined commentaries of these three scholars is known as the "Sanjiazhu" (, "commentaries of the three experts"). The primary modern edition of the "Records" is the ten-volume Zhonghua Book Company edition of 1959 (revised in 1982), and is based on an edition prepared by the Chinese historian Gu Jiegang in the early 1930s and includes the "Sanjiazhu".
