抄録 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.
