This is the 25-year official history (1469-1494) of Joseon’s 9th King Seongjong. In April 1495, 4 months after Seongjong’s death, the book started to be written down, and in March 1499, it was published and placed in a royal archive. Due to the Japanese invasion, all the annals but the one in Jeonju were lost, so from July 1603(year 36 of Seonjo) to March 1606, the book was published again. Jangseogak holds the copy from Jeoksangsan archive, but they were taken by the North Korean army during the civil war. Only a combined volume3-5 book of 『Annals of King Seongjong』 is remaining.
