Ilseongnok (Records of Daily Reflections) are the chronicles compiled by the government from the 36th year of the reign of King Yeongjo of the Joseon Dynasty (1760) to the 4th year of the reign of Emperor Yunghee of the Korean Empire (1910). They comprise 2,300 or more volumes. The Classics Publication Society of Seoul National University possesses 46 volumes of photo prints of 580 or more volumes of Ilseongnok, produced from the beginning of King Cheoljong’s reign to the end of King Gojong’s reign (from 1967 to 1974) as a part of the "Seoul National University Classics" publication project. The Kyujanggak Text Committee of the Seoul National University Library restarted the publication of Ilseongnok in 1982 and published 28 volumes up until 1991. After becoming independent in 1992, Kyujanggak accelerated the photo print project, publishing 86 photo print books (36th year of the reign of King Yeongjo-4th year of the reign of Emperor Yunghee) until 1996 to finalize the publication project, which had been an ongoing affair for 15 years.
Kyujanggak has the largest collection of old document series in Korea, comprising approximately 50,000 documents of diverse types, including king’s documents, royal family documents, official documents, private documents, organization documents, and diplomatic documents. Old document series have great value as historical materials as they depict the life of the time through first-hand accounts. However, they are difficult for researchers to use, as most are written in cursive handwriting. Under the circumstances, Kyujanggak has been textualizing and publishing old documents in its collection under the title of "Old Document' since 1986, so that researchers can access them more easily. The old documents written in cursive were textualized so that researchers in general who did not want to learn cursive characters could easily study them. The accuracy of the transcriptions was enhanced through a number of correction processes. Moreover, the descriptive form of the original accounts was maintained through the textualization process, and the bibliographical information of each document was briefly indicated. The convenience of use was enhanced through the development of an index recording the issuer, receiver, production year, and so forth. "Old Document" is published in one or two books each year in the order of king’s documents, royal family documents, official documents, and private documents.
Kyujanggak has a collection of approximately 220 types of old maps with 1,100 books, and 6,000 or more pages in total. They were produced between the 16th century and the 19th century and include maps produced by state agencies and also by civilians. By type, they are divided into 24 world maps, 53 complete maps, 20 provincial maps, 53 county and prefectural maps, 32 foreign maps, 13 defense maps, and 26 other maps. The map collection of Kyujanggak shows various aspects of Joseon society through its diversity and has enormous historical value. Kyujanggak has Korea’s largest collection of old maps and has investigated and organized them by employing researchers who are exclusively in charge of old maps. It has continuously made the materials available since 1995 through publications and digitalization.
In 1994, Kyujanggak began to select and publish photo prints of materials from its collection that were deemed essential for the study of Korean culture and heritage under the title of “Kyujanggak Collection Series.” First, Kyujanggak published Hwaseong Seongyeok Uigwe (two books) in 1994, Boin Busin Chongsu (one book) in 1995, and Mudang Naeryeok (one book) in 1996. Since 1997, Kyujanggak has been publishing its collection by category in order to promote the activation of the publication project, categorize photo print books more effectively, and allow researchers to efficiently use the materials they need. As a result, the collection was published in the form of photo print books in the four categories of law books, literature, royal protocols, and geography books. Additionally, the following were added as new categories in subsequent years: Confucian books in 2000, linguistics in 2003, and science, technology, and art in 2006. Kyujanggak completed the publication of law books in 2001 and has been publishing meteorological records since 2002. Currently, Kyujanggak is promoting publication projects in the six categories of meteorological records, literary works, royal protocols, Confucian books, geography books, linguistic books, science and technology, and art. It publishes and distributes photo prints in various fields, from legislation to political history, literature, linguistics, ideology, geography, culture, and science and technology.
On August 24, 1990, the CEO of the Keumho Group, the late Seong-yong Park, donated 500 million KRW to Kyujanggak to establish the "Keumho Koreanology Research Fund." Kyujanggak decided to use these funds to select and publish the photo prints of materials from its collection that were deemed essential for the study of Korean culture and heritage, and it has been publishing the "Keumho Series of Kyujanggak Collections" since 1991. The title "Keumho Series" was bestowed to signify the contribution made by the late CEO. A total of 100 books were published in the Keumho Series of Kyujanggak Collections from 1991 to 2006. Materials mainly related to external relationships and modern history were selected and published between 1991 and 2004, and important materials among the Uigwe of Kyujanggak were selected and published between 1994 and 1996 (the Uigwe publication project was transferred to the "Kyujanggak Collection Series-Uigwe" from 1997 onward). The publication of materials related to modern history ended in 2004, and the "Kyujanggak Collection Series-Geography" was transferred to the Keumho Series in 2005, and has been published ever since.
