본 논문의 목적은 아동 도서를 취급하는 여러 형태 중 인터넷 서점에서 제공하는 다양한 도서 정보를 좀 더 효과적으로 제공하기 위해 현재 운영되고 있는 6개 인터넷 서점의 도서 분류 체계를 분석하였으며, 특히 여러 주제 영역 가운데 '아동 도서'를 중심으로 효과적인 분류 체계를 제시하고자 하였다. 국내 인터넷 서점 중 온.오프라인 인터넷 서점을 운영하는 교보문고, 영풍문고, 반디북닷컴과 온라인인터넷 서점만을 운영하는 예스24, 알라딘, 모닝365의 특징을 '아동 도서'의 주제 영역별로 분석하였다. 또한 분석한 내용을 중심으로 KDC와 연계하여 KDC의 10개 주제 영역별로 각 인터넷 서점의 주제항목을 비교 분석하였다. 이와 같이 선정된 6개 인터넷 서점의 '아동 도서'분류 기준에서 문제점들이 들어났고, 이를 고려한 효과적인 분류체계 안을 마련하는 것이 무엇보다 중요한 것으로 나타났다. 따라서 6개의 인터넷 서점 아동 도서 분류 체계 분석 결과와 함께 KBC를 아동 전문 도서관에 맞게 변형시킨 '느티나무 어린이 도서관 분류법' 특징을 고려한 효과적인 아동도서 분류 기준을 제시하였다.

The purpose of this study is to design and develop a alternative material recommendation system using automatic classification, based on user preference. Details of usage data by users from DREAM was analysed in order to develop the way of a method on selecting proper alternative material, and then the data by user preference were allocated under each category of 10 KDC categories. The keyword, selected from the title of users' usage data from a certain period of time, were divided into 10 subject categories and ranked by the order of frequency of appearance. Books including high frequency of the keyword in title can be selected as a preferred target for producing alternative materials. Lastly, a dynamic linkage for sharing usage data among National Library for the Disabled and other libraries is proposed to produce more proper alternative materials, based on user preference.

The purpose of this study is to analyze user behaviors of books in detail based on circulation data in an academic library. It analyzes circulation patterns of books for ten years from 2006 to 2015, which are surprisingly similar every year. Each pattern follows 'Loan books 20/50 rule' that 20% core collection occupies 50% of its circulation every year. This clarifies users' circulation patterns are highly consistent and very expectable. Also, using the cumulative distribution of book age, it defines the half-life of books and suggests the mathematical formula to measure it. Circulation patterns of the whole loan book and core collection for ten years are very different in terms of subjects, user groups, and divisions. This indicates that core collection plays a significant role in analyzing circulation statistics and usage patterns for the efficient collection development in the future.

In the development of a university library's collection, the concept of patron-driven acquisition refers to a collection strategy that addresses users' direct information needs. In this study, an analysis of ten years' worth of book requests by user types was conducted to understand the topic preferences for efficient collection devleopment in the university library. In collection development, identifying subject areas of users' requested books is necessary for librarians to identify key areas of collection development and establish balanced collection development policies. To identify the major subject areas for each user group, KDC (Korean Decimal Classification) subject classifications were used, and network analysis techniques were applied to investigate the relationships between book topics in detail. The analysis revealed that "social sciences" emerged as the major topic across all user groups. However, in the analysis of sub-topics, "medicine" and "psychology" were distinctively identified as the major subject areas for graduate students, setting them apart from other user groups. The result of the network analysis further indicated that undergraduate students showed unique topics such as civil service, job placement, and career, which were not observed as major topic clusters in other user groups. On the other hand, graduate students tended to concentrate on a few specialized subjects, forming distinct topic clusters in the analysis.

There has been research to understand users' information behaviors using book circulation data of public libraries. In this study, we examined the subject areas of books simultaneously borrowed by users of public libraries and aimed to identify the relationships among the subject areas. To accomplish this, we utilized the Korean Decimal Classification codes of 984,790 loaned books in 2019 to transform the lists of concurrently borrowed books, totaling 22,443,699 records, by the same users on the same day, into vectors using the ITEM2VEC technique. Next, we extracted ten highly related classification codes for each classification code, utilizing a total of 522 classification codes to create a network. We identified 15 communities within this network and examined the characteristics of each community. Among the 15 communities, those consisting of two or more main classes allowed us to identify meaningful thematic associations. This study, grounded in users' book usage behaviors, has suggested the topics of books that could be borrowed together. The findings offer valuable insights for library collection development and placement, recommending related subject materials, and revising classification systems.

Although university libraries run by the subject-oriented serviec systems are increasing more and more, many problems are emerging as a result of tying out the subject classification of the sources without an enough advance knowledge, consideration of reality, and the study about effective management of subject-oriented sum system. Through the research of 37 university libraries run by the system of subject-oriented service, it was proved that for the effective subject-oriented service system, the reasonable classification of the subjects, considering the form and structure of the building, the number of users on each subject and the organization of the collection, and the subject librarians, who would take charge of subject-oriented service systems are indispensable. Therefore, the subject-oriented service system to be rooted strongly, the role model of the subject-oriented service system adequate to the reality of Korean university libraries should be developed, and the efforts of the people on the spot such as acquiring enough supports and training of the subject librarians should be arranged.
