The bibliography sections (
yiwenzhi ) of the
Twenty-Four Histories provide valuable diachronic data. The (111 CE)
Book of Han imperial
Bibliography records the
Zhoushu, or
Zhoushiji , in 71 chapters. The (636)
Book of Sui lists a
Zhoushu in ten fascicles (
juan), and notes it derived from the
Jizhong discovery of Jin dynasty period.
Yan Shigu (581–645), annotating
Yiwenzhi, states that of the 71
Yizhoushu chapters only 45 are extant. However,
Liu Zhiji (661–721) claims that all 71 original chapters were extant. The
Old Book of Tang (945) bibliography lists an 8-fascicle
Zhoushu with annotations by
Kong Zhao (, mid-3rd century). The
New Book of Tang (1060) lists both a
Jizhong Zhoushu in ten fascicles and Kong Zhao's annotated
Zhoushu in eight. The (1345)
History of Song and subsequent dynastic histories only list the
Jizhong Zhoushu in ten fascicles. Shaughnessy concludes that two separate versions existed up until the Tang period, the eight-fascicle
Kong Zhao zhu Zhoushu () and the ten-fascicle
Jizhong Zhoushu (). These two textual versions were assimilated during the
Northern Song period (960–1279), and the loss of eleven chapters occurred before the middle
Southern Song (1127–1279). Both these traditions, associating the extant
Yizhoushu to Jizhong texts or Kong's edition, have dubious historicity. First, contemporary research on the
Yizhoushu has conclusively demonstrated that the received text could not have been recovered from King Xiang's tomb along with the
Bamboo Annals. Shaughnessy explains that "the
Yi Zhou shu was extant as an integral text, known as the
Zhou shu , throughout the nearly six centuries from
King Xiang's burial in 296 B.C. through the opening of the tomb in 280 A.D." Some chapters (e.g., 62
Shifang ) have internal evidence of being written after the 221 BCE
Qin dynasty unification. Second, it is unlikely that Kong Zhao, author of the earliest commentary, consulted the Jizhong documents. The dates of Kong's life are uncertain, but he was a close contemporary of
Wang Su (195–256), and the last historical reference to him was in an imperial invitation of 266. Shaughnessy says Kong's commentary was added to the text "sometime in the middle of the third century A.D., but certainly before the 280 opening of King Xiang's tomb." Histories listed many scholars – but not Kong Zhao – who worked on deciphering the bamboo strips.
Yizhoushu commentaries began with Kong Zhao in the 3rd century and continue in the present day. Kong's commentary is extant for 42 of the 59 chapters, and has been included in most editions.
Qing dynasty (1644–1912) scholarship produced valuable
Yizhoushu commentaries and editions. The
text-critical edition of
Lu Wenchao (
盧文弨, 1717–1796) was based on eight
Yuan dynasty and
Ming dynasty versions, and includes twelve earlier Qing commentaries. The (1936)
Sibu beiyao series reprinted Lu's edition, which is called the "Baojing Study version". The (1919)
Sibu congkan collection reproduced the earliest edition, a (1543) version by Zhang Bo () printed at the
Jiaxing provincial academy. Compared with most other
Chinese classics, the
Yizhoushu has been neglected by scholars, both Chinese and Western. McNeal suggests, "A bias against the work, perhaps originating in part from the misconception that it comprised those Zhou documents that Confucius deemed unfit for inclusion in his canonical edition of the
Shang shu , or
Venerated Documents (which includes a section called "Zhou Documents" itself), has contributed to the relative neglect of this text." ==Parallel texts and epigraphics==
