Its name comes from the saying of Zengzi, "I examine myself three times a day". Jeongjo began recording his daily routine and studies in 1760, while still crown grandson, and after his accession had the scholars of the Kyujanggak write it up from the king’s point of view. It was kept until 1910; 2,329 volumes survive.
Where the Seungjeongwon Ilgi is a chronological log, the Ilseongnok arranges each matter under a heading (gang) and details (mok), making it easy to consult — a king’s personal diary turned into an official state record. It is a National Treasure held at the Kyujanggak of Seoul National University and became UNESCO Memory of the World in 2011.
