Abstract

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.

이 연구는 대학도서관 대출데이터를 활용하여 이용자들의 대출행태를 장서의 대출수명과 주제영역, 특정 이용자층과의 연관성 등의 다양한 관점에서 분석하였다. K대학도서관의 2006년부터 2015년까지 10년간 이용자들의 연도별 대출행태는 매해 20%의 대출도서가 전체 대출의 50%를 차지한다는 '대출도서 20/50 법칙'을 따르는 것으로 확인하였다. 또한 각 대출도서의 도서연령과 대출횟수의 연령별 누적분포를 구하여 도서 반감기를 정의하고 이를 수식화하였다. 종단적 관점에서의 핵심장서를 산출하여 그 특성을 주제별, 구성원별, 계열별, 연도별 등의 측면에서 분석하였다. 종단적 관점의 전체 대출도서와 핵심장서의 대출패턴은 모든 측면에서 매우 상이하게 분석되어 10년 동안 꾸준히 핵심장서로 분류되는 도서들의 역할이 있는 것으로 나타났다. 이는 10년간 꾸준히 대출되는 도서, 즉 핵심장서의 특성이 명확하다는 의미이며, 이러한 특성을 반영한 효율적인 장서구성정책을 개발할 필요성이 있다는 근거가 된다.
