よくある質問 - 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.

Initially, there was a bug that prevented the retrieval of "Full Issue" among the items in the Japanese Periodicals Index, resulting in data with no issue. The bug has now been resolved by displaying "Full Issue" as "Issue" in accordance with the specifications of CiNii Articles.
