《鉛書》是江西鉛山縣的一部縣志，刊於明萬曆四十六年(1618)。該志體例殊異，卻保存不少寶貴的古代社會經濟史料。特別是礦冶開發紀錄極為詳實，當中分述了鉛、銅、鐵、銀等各類礦產的開採冶煉技術。而這些礦冶史料，其實多來自宋代吳紹古撰修的《永平志》記載，更是反映目前已亡佚的《浸銅要略》部份內容，至今學界尚無討論研究。因此本文將就《鉛書》中的礦冶開發史料，略加爬梳整理，探究其成書背景與理念。

Yen Shu 鉛書 is a county gazetteer of Yenshan of the Jiangxi Province published in 1618. Compared with other county gazetteers, its composition format is unique. Moreover, it preserves valuable social and economic data of the ancient times. Especially noteworthy are its detailed records of technological advances in the mining and smelting of lead, copper, iron, silver and so on. More importantly, several records are drawn from works of the Song dynasty such as Yongping zhi 永平志 (a Yenshan county gazetteer in the Song times) and Jintong yaoyue 浸銅要略 (The Essentials of Steeping Copper). These data, however, have not been examined in current scholarship. This article aims to analyze both the compilation of Yen Shu and its records about advances in mining and smelting technology.
