Korean Studies Advancement Center houses a total of 364,550 materials that encompass 111,076 old books, 183,175 archive materials, 63,909 woodblocks, 949 signboards, and 3,028 paintings and calligraphic works as of December, 2012. The collection of literary works is a total of 25,155 works. It is identified that the literary works includes 3,940 printed works and 868 manuscripts, after checking and excluding the same works. Importantly, the type number of literary works is influenced by inclusion of a man``s history(實紀) and writings of several generation(世稿). This paper examined the works including both a mam``s history and writings of several generation. It may be impossible to analyze the whole collection of literary works in a limited time. Therefore, this paper focused on ``Ga`` section of the collection that Korean Studies Advancement Center houses. The works of which titles belong to the ``Ga`` section are a total of 522 editions. The main findings of analyzing 522 literary works are as follows: ① In terms of the published year of the works, the period from 1600 to 1910 are about 28% as of 146 works. The literary works published after Chosun Dynasty had been annexed by Japan are 23.9% as of 125, which is a similar rate to the late Chosen Dynasty. The works published after liberating from Japanese colonial rule are 36.6% as of 191 works. Additionally, as adding works of unknown published year presumed to be published in the 20th century, the total works published after liberating from Japanese colonial rule are 48.1% of 251 works. ② The literary works that periods of birth and death of authors were known are 383. The majority of authors, about 50% of them, worked after 19th century. As the results show that old intellectuals worked extensively in the 20th century, which suggests further study on those authors. ③ In terms of published types, the most types are lithographic printed works and amount to 39.5%. Also, the entire numbers of copied photoprinted editions(7.8%) and typeprinting editions(4.4%) are 51.7%. This finding shows that most of them were published after Japanese colonial period. Generally, there are some differences between manuscriptal original editions and published editions. Currently, Korean Studies Advancement Center houses 868 manuscriptal editions. Unpublished manuscriptal editions have high value of utility as original materials. However, there are considerable differences between published and original editions because of the compilation system of literary works. As original manuscripts include some poetry and letters that are not identified on published editions, they can be very helpful to further study. Although ``Wolchonjip`` of Chomok(趙穆)`s works has both original and woodblocked editions, many contents of woodblocked editions were deleted from original manuscripts. This case shows that the contents of original edition were eliminated for publishing process due to the political change of Injo``s Enthronement(仁祖反正) and severe conflicts of Seoae-Wolchon. This paper suggests four issues for future study on literary works: ① It should consider the range and network for practical use of literary works. ② It requires to analyze participants related to publishing original editions. ③ It should take notice of differences between originals and published editions. Literary works are primarily authors`` writings but editors` perspectives play significant roles on completing published editions. ④ It needs to have interest in literary works published in the 20th century. As this paper stated above, 50% of literary works were published and most authors worked actively in the 20th century. This paper analyzing literary works can contribute to reconstruct the history of intellectuals, ideas, and literature in the period of Chosun Dynasty as examining the publishing process and related publishers and editors.
