Incorporated Jxiv preprints from JaLC and adding coverage from NDL Search

CiNii Research data sources: NDL Search now also includes bibliographies from the National Diet Library Periodicals Index Online Collection and article-level bibliographies from the National Diet Library Digital Collection (e-books and e-magazines).

In addition, preprints from JaLC have been newly included. This means that JLC ​​preprints, including those published on Jxiv, can now be searched on CiNii Research.
