Yiwenzhi


The "Yiwenzhi", or "Treatise on Literature", is the bibliographical section of the Book of Han authored by the Chinese historian Ban Gu, who completed the work begun by his father Ban Biao. The bibliographical catalog is the last of its ten treatises, and scroll 30 of the 100 scrolls comprising the Hanshu.
The basis for the catalog came from the "Qilüe" by Liu Xin, which gives detailed bibliographical information about holdings in the Imperial Library, which itself was an extension on Bielu by Liu Xin's father Liu Xiang, on which the two had collaborated. The catalog provides important insights into the literature of the various Chinese intellectual currents of the pre-Qin period, of which only some 20% are presently known.

Origin

The "Yiwenzhi" closely adheres to the bibliographical system devised by Liu Xiang and Liu Xin with minor exceptions. The introductory paragraph of the treatise, most likely taken verbatim from Qilue, is quite informative:
"Many books were in great disarray in the time of Chengdi, upon which Chen Nong was ordered to collect all the books in the world, and high officials to collate books in the Imperial Library; Luminous Grand Master, Liu Xiang, was put in charge of works by the Confucians, the philosophers, and the shi and fu poets; Lieutenant General of the Shanglin Imperial Garden Garrison, Ren Hong, of works by militarists, Grand Astronomer-Historian, Yin Xian, of works by astrologers and diviners, and Surgeon to the Emperor, Li Zhuguo, of works by herbalists and alchemists. Liu Xiang wrote an abstract for each completed work, catalogued, and memorialized it to the emperor. Liu Xin expanded the system to cover a great many books, and memorialized the Seven Abstracts, or the Qilue."
Liu Xin created a seventh domain Jilue to separate books he himself wrote, but Ban Gu, while using Liu Xin's Qilue material, reverted to the six-domain system of Liu Xiang, and reclassified Liu Xin's works into the other six domains. Furthermore, Ban Gu added titles that appeared after Qilue and before his time of writing the Hanshu, including some of his own.

Material and morphology

Scrolls in bamboo strips, mostly for text, were referred to as pian, while those in woven silk, mostly for large pictorial representations, as juan ; both are called scrolls because they were rolled up, bound, and tagged for identification. The practice of using scroll pouches called ji to hold five to ten scrolls had been in existence, but paper had not been invented by Cai Lun until 13 years after Ban Gu's death. The earliest form of back-bone binding of books, the butterfly binding, was not invented until around 1000.

Research

Commentaries on "Yiwenzhi" were done by Yan Shigu and Wang Yinglin. Modern researchers on the topic include Gu Shi, Chen Guoqing and others.

Comparison to the ''Pinake'' of Alexandria

The Hanshu Yiwenzhi catalogued the Former Han Imperial Library holdings under "6 domains, 38 classes, 596 families; 13,269 scrolls in all" concludes the treatise. An estimated 20% of the titles are extant today. This compares favourably with the estimated 10% survival of the Pinakes titles that consisted of works in Greek, Egyptian, Aramaic, Hebrew, Persian, and other languages, in the Great Library of Alexandria of the 3rd century BCE, which according to one tradition, at one time held some 120,000 parchment scrolls and papyri.
