FAQ - データについて

Initially, CiNii Research imported only the data of academic journals (academic society journals, university bulletins) and Nikkei BP related journals from the data of the Japanese Periodicals Index, but, after April 8, 2022, all data will be imported. .

In order to improve the efficiency of the data acquisition method, the data acquisition method of the Japanese Periodicals Index has been changed from the acquisition method of CiNii Articles. As a result, we have not been able to obtain publisher information. We are working to get it.

There is a problem that "serial issue" cannot be obtained from the items of the Japanese Periodicals Index, so there is data without the issue. We are working to get the item of "serial issue".
