This is the original manuscript of the journals written from January 1760 (36th year of King Yeongjo of Joseon) to August 1910 (the 4th year of Yunghi, or King Sunjong, the last king of Joseon). These journals were presumably initiated from Jonhyeongakilgi written throughout the years of King Jeongjo while he was a crown prince and after he was enthroned. The whole set of volumes amounting to 2,329 pages survived, though the records for a period 21 months are missing. These journals are invaluable because they supplement Joseon Wangjo Sillok (Annals of the Joseon Dynasty) and offer even more interesting details to study the late Joseon Dynasty.
