Abstract

How has the use of academic journals changed since the academic library purchase policy changed from selective journals based on core journals to package purchases by big deal? The purpose of this study is to analyze the effect of supply and size of academic journals in university libraries on the use of journals. For this purpose, this study used the actual usage statistics of e-journals of K Academic Libraries during 2013-2015. The analysis shows that there is a so-called long-tail shape in which demand shifts to niche products that are effective in online platforms. Analysis of the use of academic journals by year for three years showed that the use of electronic journals in K Academic Libraries appeared to be a perfect Pareto shape, which is concentrated in the top 20% of journals. In particular, in 2015, the top 5% of journals accounted for nearly 80% of the total usage. Despite the changes in the supply method and size of academic journals, users' use of journals was still concentrated in core journals.

전자학술지의 등장으로 대학도서관의 학술지 구입정책이 핵심저널에 근거한 선택적 수서에서 빅딜에 의한 패키지 구입으로 변화하였다. 이와 관련하여 이용자들의 학술지 이용은 어떻게 변화했을까? 이 연구의 목적은 대학도서관의 학술지 공급방법과 규모의 변화가 이용자들의 학술지 이용에 영향을 미쳤는지를 분석하는데 있다. 특히 온라인의 등장으로 이용자들의 학술지 이용이 확대되는 롱테일현상이 나타나는지에 초점을 뒀다. 이를 위해 K 대학도서관의 2013~2015년 동안의 외국 전자학술지의 실제 이용통계를 사용하여, 학술지 이용에 있어 온라인플랫폼에서 유효한 틈새상품으로 수요 이동이 발생하는지를 살펴보았다. 3년 동안의 연도별 학술지 이용 분석결과 K 대학도서관의 전자학술지 이용은 과거에 비해 학술지의 규모가 비교할 수 없을 만큼 증가하였음에도 불구하고, 여전히 상위 20%의 학술지에 그 이용이 집중되는 파레토현상이 나타났다. 특히 2015년의 경우는 상위 5%의 학술지 이용이 전체 이용의 거의 80%를 차지하는 현상을 보여, 수퍼스타효과를 나타냈다. 이처럼 학술지의 공급방식과 규모의 변화에도 불구하고 이용자들의 학술지 이용은 여전히 핵심저널에 집중되어 있음을 확인할 수 있었다.
