Jigulu 稽古錄 "Research into antiquity" is a concise handbook on history written by Sima Guang 司馬光 (1019–1086). The 20-juan long Jigulu is a by-product of his large project, the univeral history Zizhi tongjian 資治通鑑. It can be said that it is a kind of practical overview over the Zizhi tongjian, with additions to the time before the year in which the sets in, 404 BCE, up to the reign of the mythological emperor Fu Xi 伏羲.
From the year 841 BCE on, the text is written in an annalistic form. The Jigulu also gives an overview of the events of the early Song period 宋 (960-1279) down to the end of the Zhiping reign 治平 (1064–1067). The title of the book is derived from a sentence in the Confucian Classic Shangshu 尚書, where information is sought about the mythological emperor Yao 堯.
The Jigulu was submitted to the throne in 1086 CE. There were originally two different versions, the so-called Tan version 潭本, which has survived, and the Yue version 越本.
The Jigulu is included in the collection Zizhi tongjian huike 資治通鑑彙刻. It was printed separately in 1501, during the late Ming period 明 (1368-1644) and in 1872. It is included in the series Tianyige congshu 天一閣叢書, Sibu congkan 四部叢刊, Xuejin taoyuan 學津討原 and Siku quanshu 四庫全書. A modern edition was published in 1986 by the Zhongguo youyi press 中國友誼出版公司.
