This study analyzed the structure and utilization of subject headings in the National Library of Korea Subject Headings List (NLSH) based on an analysis of subject headings assigned to 1,218,867 national bibliographies from 2003 to 2022. The findings of the study are as follows: Firstly, among all subject headings in the NLSH, there were 257,103 preferred terms, accounting for 50.2% of the total terms. Foreign language terms constituted 33% (169,466), while non-preferred terms comprised 12% (61,442). Among the preferred terms, 57,312 subject headings were used, accounting for 22.3%. However, it was observed that 54.7% (31,351) of these subject headings were assigned less than 5 times, indicating that only a small number of subject headings were frequently utilized. Secondly, the frequency of relationship indicators appeared in the order of RT, BT, and NT. The NLSH consisted of 12,602 top-level subject headings and 143,704 lowest-level subject headings, with a maximum depth of 17 levels. Thirdly, on average, 1.72 subject headings were assigned per bibliographic record. The number of subject headings assigned and the depth of the hierarchy increased for materials with more specific contents. Recent bibliographic records have been assigned more subject headings and deeper into the hierarchy of the NLSH. It was also found that the number of subject headings assigned per bibliography varied depending on the main class of KDC. Based on the findings, it is recommended to evaluate the coverage of terms in the NLSH, reorganize hierarchical relationships and depth of subject headings, and enhance the development of subdivisions within the NLSH.

The study confirmed that the methods for expanding headings and combined structures among the headings, subdivisions, qualifiers and inverted terms were diverse, and that the headings used for similar purposes do not have identical structural forms. It is also found that the standard symbols representing generic relationship in theasurus, which are introduced in the list of subject headings, do not show precisely the hiearchical relationship of phrase headings. MeSH in pre-coordinated system will be available for retrieval in the computer environment because it can make a link between headings and subdivisions in searching stage. The changes in retrieval circumstances and the seeking behaviors of the users demand that a new structure of subject headings be developed. It was proposed that the modification of the structure in the Hangul subject headings be essential.

This is the survey on the actual condition about the managing of headings in library cataloging. KCR4, the standard rules for the library cataloging in Korea, has no rules for the main entry headings and uniform headings. But the cataloging records are not standardized because a lot of libraries in Korea use the main entry headings and uniform headings yet. A structural revision of KORMARC is required in order that all library follow the rules on the KCR's main entry headings. And the rules for uniform heading used until KCR4's policy about the heading is decided according to international trends are needed.

The purpose of this study is to analyze the historical process and characteristics of subject headings related to Korea, China, Japan in the LCSH, from the first edition to 31th ed. The analytic results show that the headings in the 31th edition include in Korea 713, China 1,742, Japan 2,647, compared to Korea headings 4, China headings 49, Japan headings 24 in the first edition. Some subject headings considered important and essential are left out. We can also recognize the some headings are relatively too subdivided. The omitted and insufficient Korean, Chinese, Japanese subject headings are considered to be tied up with library policies of LC. Therefore our active support such as donation are being called for collecting more detailed analysis of Korea, China, Japan-related publications in LC.

This study selected Korea and China-related subject headings among all names contained in Japan 2008 Version of NDLSH, and compared and analyzed the number of headings and the features according to each theme. As the result of analysis, the total number of Korea-related subject headings is 222 including its headings and referent words. At comparing with China-related subject headings, the number of Korea-related subject headings was very small size, and shows many limits in terms of the variety or the specificity of themes. Especially, the facts that 'Joseon', which is not existed any longer, is used as Korea's nation name, or that Balhae's history is assigned into Chinese history are required to be corrected quickly. Meanwhile, in the China-related subject headings field, multi-racial nation's features are reflected. and are contained many theme names like ancient racial names, each minority's residental area name and its native language which are rarely appeared in Korean theme names field.

The purpose of this study was to propose the improvements for high quality of National Library of Korea (NLK) Subject Headings List which was developed as a subject access tool in 2002. For this study, literature review, case study for subject headings lists of national libraries, and data analysis of headings and relationships were performed. Several problems were found as follows: inconsistency of subject headings descriptions, unclear and unnecessary relationships among headings, inconsistency of hierarchical relationships, lack of currency, incorrectness of classification numbers, duplication of newly requested terms, and assignment of non-preferred and unregistered terms in bibliographic records. Focusing on these problems, modifications of subject headings and bibliographic records, installation and operation of an review committee on subject headings, and supplementation of a manual were suggested to improve NLK Subject Headings List.

Subject headings support the effective access of children's picture books. However, it is difficult to select subject terms from titles or table of contents in children's picture books because of their relatively little textual information. Therefore, it is necessary to assign subject terms to each picture book. However, it is not adequate to use general subject headings because the types and levels of general subject headings are different from special subject headings for the children's materials. For this reason, this study aims to develop subject headings for children's picture books. The subject terms in A to Zoo were selected, and the selected terms were translated into Korean and modified for the Korean culture and language. Other reference books, such as Elementary Korean Dictionary, were also used to determine adequate terms for children. The resulting subject headings were assigned to the recommended picture books for children and used to search by subject, browse, and recommend books.

LCSH is now used as a major subject access tool in library catalogs and national bibliographies. Internationally, LCSH has also gained wide acceptance. Over the years, many libraries in other countries have adopted or adapted LCSH. The purpose of this study is to analyze the historical process and characteristics of subject headings related to Korea in the LCSH, from the first edition to 30th ed. The analytic results show that the section of Korean history and related subject headings are different from the terms used in Korean academic world : Some subject headings considered important and essential are left out. We can also recognize the some headings are relatively too subdivided. The omitted and insufficient Korean subject headings are considered to be tied up with library policies of LC. Therefore our active support such as donation are being called for collecting more detailed analysis of Korea-related publications in LC.

The purposes of this study are to review the historical development of food and culture in the KDC (Korean Decimal Classification) and to propose improvements of the KDC to classify materials of food and culture by using the KDC effectively. First of all, changes of classification numbers and headings related to food and culture from the 1st edition to the 5th edition of the KDC were examined. Recent books about food and culture were examined and were classified according to the latest edition of the KDC. Several problems were found including a lack of headings, including notes in food and culture, a lack of headings about Korean foods in particular and reflections about various foods from other countries, a lack of detailed relative headings, and the remaining western oriented headings. Other classification systems about food and culture were analyzed and it was found that there was a need to have new headings for classifying Korean traditional foods and table services, new formats for a relative index, detailed notes, and changes in western oriented headings.

This paper suggests a way to improve Korean diaspora-related subject headings based on the analysis of terminology about Koreans in Korean diaspora-related manuscripts and investigation of related terms in the National Library of Korea subject headings. After selecting three KCI journals with high ratios of diaspora-related papers, the study extracted Korean-related terminology from the journal papers and examined their term frequencies. Additional Korean-related terms were investigated by manually reviewing the articles in which extracted terms appear. Based on these analyses, the study proposes several supplemental enhancements to Korean-related topic names in the National Library of Korea's subject headings, such as changing the English notation, adding non-preferred words, and changing the hierarchical relationship of the existing topic names.
