For decades, the cost of academic journals has been increasing, and academic libraries have had to cope with this situation. The “Big Deal” subscription model is no longer available for many libraries. In this study, the Nature Publishing Group Pay-Per-View (PPV) service: Articles on Demand (AOD) is examined from the perspective of costbenefit.This study also examined whether the AOD model fits the needs of researchers. To demonstrate the cost evaluation and usage features, the AOD access log was examined. Globally, the AOD cost is lower than that of any other type of subscription contract. AOD cannot be archived, but the AOD log indicates that recent material is accessed more frequently than older material. Old papers are not used. After the introduction of AOD, the number of used titles increase by more than two times the previous number. AOD fits the potential needs of researchers. Major usage concentrates on specific journals, while minor usage extends to a wide range of titles. The combination of a title-based contract with PPV would be an effective means of coping with the increasing costs of academic journals.(著者抄録)
