This study analyzed Korean university libraries' holdings of Western language books published in 2003 and 2013 using the KERIS union catalog with a view to investigating the changes in collection development of Western language books in the libraries. To do that, new collection indexes - holding h-index, CUI (Collection Uniqueness Index), and CCHR (Common Collection Holding Ratio) - were suggested, and they were used with basic indexes such as the number of titles, the number of books, and the number of books per title. The analysis reveals that compared to those published in 2003, the number of titles was decreased by 16.1% with those published in 2013, and the number of books dropped more sharply, by 42.2%. Also, in 2013, CCHR was decreased while CUI was increased. In terms of subject, among DDC main classes, 0XX (Generalities) showed the greatest decrease rate in both the number of titles and books because of the radical reduction of computer-related books. In terms of each library's holdings, the number of Western language books held by top libraries has been increased with those published in 2013.

Recently, domestic interest in gender equality is increasing, and it is expected that the demand for the collection of children's gender equality in the library will increase due to these social changes. In this study, the top 10 public libraries in Korea were selected from the list of collections of gender equality books and collection / loan data presented by various institutions such as public libraries and 'children's library research groups'. For this purpose, 10 libraries in Korea were selected and analyzed quantitatively and qualitatively through the collection status of the gender equality collections, loan status, turnover, Bonn's use Factor, and Trueswell's 80/20 rule. Based on the results of this analysis, we would like to suggest some issues to be reflected in library development policy of the future.

This study analyzed the library's library development policy at home and abroad, established basic principles and guidelines for the library's library development policy, and proposed details of the library's library development policy. In this study, the vision of the supreme court library was established as an open legal and judicial information center that provides services to the public at the eyes of the general public, as well as a representative law library that focuses The five basic directions for establishing a book development policy to realize this vision are as follows: 1) Book development centered on mission and responsibility as a national representative legal library, 2) Development of books as an open legal/judicial information center for public service, 3) The development of books in line with the changing times and information environment, 4) Development of books by subject and language considering the characteristics of the court library, 5) Development of a collection, preservation, and disposal of data based on consistency and systematicity. It is expected that systematic or strategic book development can be promoted through the development of books in the court library based on policy documents.

This study analyzed the previous studies and utilization cases on library big data, and based on this, analyzed the collection/circulation data of the library big data platform and tried to derive meaningful analysis results. And five analysis indicators were selected: the increase rate of collections by annual, the composition of collections by subject, the composition of unborrowed collections by subject, the rate of borrowed collections, and use factor by subject. The analysis data is 6,722,603 cases of collection/circulation data from 33 public libraries in Busan. The main analysis results are as follows. First, it was found that the gap in the number of circulation was larger than the number of collection in the 33 public libraries. Second, the annual increase rate of collections also showed a clear decline. Third, each library showed a similar pattern in the composition of both the collections and the unborrowed collections by subject. Fourth, it was found that users' circulation were very different by subject and library. Fifth, in most libraries, the rate of circulation of collections and use factor in the natural science field were the highest.

The description of resources at collection-level is being recognised as an important component of information services that seek to provide integrated access to distributed resources. This research investigated the concept, necessities, and standards of collection level description which manages heterogeneous and distributed resources effectively. Also this research reviewed collection level description projects in other countries to show a new direction of subject access in digital libraries.

In this research, a sample was selected from a public library in Paju city, which operates a regional collaborative library system. They collected data on materials, usage, and acquisition. An analysis of book collection data and usage data was also conducted in order to evaluate the correlation between the usage and acquisition by comparing overlap of purchased materials. As a result, circulations and the interlibrary loan (ILL) borrowing requests were differentiated by topics according to targeted materials, and that these characteristics affect the overlap of purchased materials. The study suggested that public libraries in the region collaborative library system need to consider the paradigm of collection and access when purchasing books.

This study investigated the classification performance of a kNN classifier using the feature selection methods based on document frequency(DF) and collection frequency(CF). The results of the experiments, which used HKIB-20000 data, were as follows. First, the feature selection methods that used high-frequency terms and removed low-frequency terms by the CF criterion achieved better classification performance than those using the DF criterion. Second, neither DF nor CF methods performed well when low-frequency terms were selected first in the feature selection process. Last, combining CF and DF criteria did not result in better classification performance than using the single feature selection criterion of DF or CF.

Currently, collections with public libraries are evaluated only on the basis of simple data, such as the use volume of collections with individual libraries, and interlibrary lending (ILL) results. To promote the ILL of regional libraries and raise the use of collections, however, the evaluation of collections should be expanded from individual libraries to regional libraries. This study aims to propose user-oriented methods for evaluating the library collections within a regional library system by using four kinds of data: collection, acquisition, circulation, and ILL application data. The results of this study show that the proposed method can reveal the positions of each library within a regional library system, and also the characteristics of a library's collections and users' needs more precisely.

It is necessary to find a genre classification by reflecting the needs of users since a subject that makes up the highest proportion of books in the school library is fictions in literature and KDC cannot accept user's need to access fiction in school libraries. This study suggested the genre classification for fictions in school libraries through surveying classification of fictions in domestic and foreign libraries, and comparing between classification systems of online/offline bookstores, KDC and DDC. For developing the genre classification system, it is to collect genre terms for fictions, to extract 14 genre headings among them, and to assign the acronym of English genre terms as classification notation. For applying the newly developed genre classification, KDC number of one middle school library was converted as the 3 methods such as combination of KDC, genre term before 800 and only genre terms. This study could contribute to suggest the genre classification of fiction to reflect user needs and to overcome the limitation of hierachical classification in KDC.

This study attempted to analyse the collections of public libraries in terms of their subject distribution and currency. It was expected that the analysis would give public librarians some suggestions as to their collection development policy making. This study team selected 423 Korean public libraries across the country and scrutinized the collections by their classes of Korean Decimal Classification(KDC) and publishing years. The study results indicated that there was some subject disproportion in public library collections. Literature and social sciences were accounting for 54.8% of whole collections. Currency of collections of public libraries could be said relatively excellent. It was found that 64.9% of whole collections had been published after 2000.
