解説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)

特集Prior studies have shown that redundant use, such as systematic downloads, repeat payments for the same article, and careless purchasing, is a problem associated with unmediated Pay-Per-View (PPV) models. The present study explored whether an alert message is an effective means of reducing redundant use. Two unmediated PPV services were compared: the Nature Publishing Group PPV: Articles on Demand (AOD) model, and the Elsevier Science Direct PPV (SD-PPV) model. The SD-PPV utilizes an alert function, while the AOD does not. To demonstrate the effects of the alert, the PPV access log and the COUNTER log were examined. The AOD access log contained several cases of continuous downloads, with a maximum of 16 downloads in one minute. In the SD-PPV log, no cases of suspected systematic downloads were found. More than one-third of the total AOD usage consisted of repeat access to the same articles. In the SD-PPV, only one-eighth of the total usage was for the same articles. The COUNTER log showed that abstract access for the AOD titles accounted for only 14 percent of the full-text usage, and this rate was one-fifth of the rate for SD-PPV. An alert before the retrieval of PPV full-text was useful for limiting redundant use. To make this system more efficient, the alert message should be improved so that it is easily understood by any user.
