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 copy is significant in that it was the first book ever to be compiled by a Korean government. Its objective view of history, coupled with its nationalism, make it a highly valuable work. This copy is printed based on the woodblocks supplemented by 1512, and has been preserved well. It is a complete set of nine volumes with no missing pages, whose contents were printed on woodblocks from the Goryeo and Joseon periods, thus giving a clear idea of how block books were made and kept at that time.
