ABSTRACT Libraries are encountering hostile conditions around journal licensing such as limited budget, the high price of packages, and vendor-led negotiation. They need to collect and analyze usage data of electronic journals to develop electronic journal collection ap- propriate for their own circumstances. The purpose of this stud y is to suggest an practical guideline for librarians’ analysis of electronic journal usage statistics. For this, the study reviewed related previous studies and examined curren t state on usage statistics provided from COUNTER release 3 compliant vendors. Finally this study proposed five core statistics including full-text article request per journal, journal using rate, price per full-text article request, most use group, and low use group, and further discussed how to use them effectively for the electronic journal management.
