Goryeosa

Goryeosa (), or History of Goryeo, is an extensive historical record of the Goryeo dynasty, compiled by the officials of Goryeo's successor state, Joseon. Its compilation started during the reign of Taejo (the founding monarch of Joseon), was completed under Munjong, and was first printed under Danjong. Goryeosa consists of 139 volumes and stylistically follows Chinese historiography () (cf. chronicle, ) where sections are organized by their purpose. The section compiling the annals of the kings, sega () narrates the history of Goryeo kings. The monograph section, ji (), contains "accounts of the politics, economics, personnel (civil and military), geography, astronomy, and other topics related to Goryeo society." The biographies section, yeoljeon (), describes notable officials. The chronology section, yeonpyo () lists the names of kings and their reigns. The listing section, mongnok (), is the table of contents of the entire compilation.

In 1452, a year after the completion of Goryeosa compilation, Kim Chongsŏ and 27 other historians authored a 35-volume complementary summary of Goryeosa, Goryeosajeolyo (Essentials of Goryeo History). Goryeosajeolyo is written in chronological order, deviating from Chinese historiography that divides sections into important subjects (e.g., kings, traitors, notable officials, chronology, and monographs) and thus is prone to duplicate recording of the same event.
