The Annals of the Joseon dynasty stored at the Odae-san Archives have two types of versions. From the Annals of king Taejo’s reign through the Annals of king Myeongjong’s reign are in fact ‘proofread versions’ which were only awaiting the final evaluation session, while the Annals from king Seonjo’s reign and then the annals of later kings were completed versions that were officially published, same as the Annals stored in other regions’ archives. Reason for preserving proofread versions instead of the final versions was because the task of creating new copies of the entire Annals of the Joseon dynasty during the reign of king Sonjo heavily costed for the government and it also required a large volumnes of paper. The entire process of storing the printed Annals at Odae-san mountain, including the copying process, renovation of the storage facility, and condition of the materials at the time of storage were all recorded in the “Shillok Hyeongji-an” record. We can see in exactly what kind of manner they were stored and preserved. The Annals of the Joseon dynasty Kept in the Odae-san storage facility were stolen and illegally shipped out of the country, and landed in the Tokyo University in Japan during the Japanese occupation of Korea. They were almost obliterated during the Gwandong Earthquake (that 생략) occurred in 1923. Surviving documents in the catastrophe were only 74 volumes, of which 9 volumes were from the Annals of king Seonjong’s region, 50 volumes were from the Annals of king Jungjong’s reign, and 15 volumes were from the Annals of king Seonjo’s reign. The first two groups of surviving volumes were the aforementioned ‘proofread version.’ Wrong letters were replaced with right ones, while some new ones were added. Portions needing corrections were highlighted in red, or checked with x or O, which show us how proofreading procedures were at the time. The most usual types of mistake made by the people of the time are evident, and in some cases the era-title for a specific Chinese emperor is mis-recorded, suggesting that the copying task was mostly undertaken by technicians. In the future, they should be further compared with Annals stored at other facilities.
