Samguk sagi (Historical Record of the Three Kingdoms; National Treasure No. 322-1) is a major work about the Three Kingdoms Period written in the biographic-thematic style and compiled by Kim Busik (1075-1151) in 1145 (the 23rd year of the reign of King Injong of Goryeo). Together with the Samgukyusa, the Samguksagi is regarded as the basic historical material for students of the Three Kingdoms Period. This particular copy was printed by the city of Gyeongju and sent to the Oksan Seowon School in 1573 (the 6th year of the reign of King Seonjo of Joseon). It includes copies printed with the original woodblocks engraved during the Goryeo dynasty, the woodblocks that were re-engraved during the reign of King Taejo of Joseon, and those that were re-engraved during the reign of King Jungjong of Joseon.
This well-preserved copy consisting of nine volumes constitutes a complete set of the work. As such, it sheds light on how it was distributed at that time (1573), the types of paper and binding used in its production, the trend of academic research, and the status of woodblock printing during the mid-Joseon period.
