A. The principal geographical descriptions compiled by the government during Yi dynasty started from the Shinchan-Paldo-Chiriji(新撰八道地理志) which was compiled by the royal decree in the sixth year (1424) of King Sejong(世宗) and it ended in the Jungbo-Munhonbiko(增補文獻備考) which was published in the second year(1908) of Yunghyi(隆熙). The process of their compilations can be divided into four steps according to the compilatory work's contents of the principal geographical descriptions which were compiled through the Yi dynasty. We can say that the first step (1424-1454) of those works began at the date of the compilation of the Shinchan-Paldochiriji and it ended in the date of the compilation of the "Sejongsilok-Chiriji"(世宗實錄地理志), and during that period the Kyonsangdo-Chiriji(慶尙道地理志) was published. In the second step(1455-1531), were published the Paldochiriji,(八道地理志), Kyongsangdosokchanchiriji(慶尙道續撰地理志), DonggukYojisungnam(東國與地勝覽) and the third step (1532-1769) began at the date of the compilation of the Dongguk-Munhonbiko(東國文獻備考) and it ended in the date of the publication of the Jungbo-Munhonbiko(東國文獻備考), and in that period the Jongjung-Munhonbiko(訂增文獻備考) was published. The works of compilation of the Eubjis in the period of King Kojong(高宗) came within the category of the fourth step. B. Generally speaking, the state geographical descriptions were composed of the regional data of the country which were collected and arranged. In other words, firstly, the Eubjis were compiled in each county, secondly, the Dojis(道誌) were compiled based upon the collections of all the Kunjis(郡誌), lastly, the government collected all the Dojis and compiled them into the state geographical descriptions. The Eubjis in the early days of Yi dynasty were compiled as the data for the compilation of the nation-wide geographical descriptions, but the Eubjis in the age of King Kojong were compiled as the administrative data. C. The main contents of the Eubjis were composed of the descriptions on the geography, history, industry, naval and military affairs, traffics, communication, administration, economy and society, and of the matters on the prose and poetry, persons of loyalty, historic remains, social customs and schools. Consequently, the above-mentioned data will be contributed to the study on the structures of the geography, history, economy, administration, education, naval and military affairs and traffics as well as the study on the literature, social customs and bibliography. Especially, they will be important data for the arrangement of cultural assets of our country. Furthermore, because the traditional study of national literature was centered around the study on the central government ignoring the study on the regional matters, the study of the Eubjis will be worthy of being valued.
