While research on Warring States, Qin, and Han manuscripts is flourishing, much less is known about the use of manuscripts during the earlier stages of Chinese history, for which material evidence has not been preserved. Based on the layout features and textual anomalies in the Western Zhou bronze inscriptions, this article explores the traces of use of perishable writing supports in the process of the production of bronze inscriptions in this period and reconstructs their functions and physical qualities. Based on the surveyed evidence, the article posits that two distinct exemplar manuscripts were used in the inscription-making process: an original “master copy” that was kept aside for proofreading purposes and a secondary “blueprint” that was employed directly in the technical process of inscription-making. A single blueprint would be used consecutively by several craftsmen to produce a set of inscriptions on different types of vessels. The word count and layout of many inscriptions were already carefully planned during the process of their composition, and any study of a bronze text should therefore begin with the evaluation of its visual qualities. Moreover, this probe provides unambiguous evidence for the use of tube-lining in the inscription-making process and reconstructs the complete chaîne opératoire of bronze inscription production in the Late Western Zhou period. The article also offers insights into the level of literacy and the division of labor in bronze workshops, and touches upon the display function of bronze epigraphy during the Western Zhou period.

This article examines the attitudes of Warring States textual witnesses to the increase in presence of and reliance on bamboo manuscripts in communicating knowledge. Based on a rereading of transmitted materials and four manuscript texts (*Wuwang Jianzuo A and B, *Baoxun, and the Zhou Wuwang you ji) from the Warring States period, I analyze how contemporaries dealt with questions about the status of (manuscript) texts, their use and transmission, their trustworthiness, and their ability to preserve knowledge. These are texts that talk about themselves. They remark upon the physicality of text and the act of writing, the problem of oral and written transmission, and the differences in the ability of memory and manuscripts to store, hide, and reveal knowledge. I argue that these different reflections reveal a change in the predominant medium of communicating knowledge towards an increased reliance on bamboo manuscripts gradually and partially replacing traditional knowledge practices.
