Kōseisha Zasshi Kiji Sakuin Shūsei Database (ざっさくプラス)
This combines content previously available in its other databases, such as MagazinePLUS. It indexes journals published in the Meiji, Taishō and early Shōwa periods, as well as minor journals that were published in local prefectures and cities.
This database is one of several major journal index databases available for Japanese journals. It is the only one that provides an index of journal articles published in the Meiji, Taishō, and early Shōwa periods to the present. It also contains important local journals that were published in prefectures and cities that are not in the NDL journal index. Users can search terms in the modern language for words changed historically. In addition, each search clarifies which Japanese university library holds the specific journal and desired article.
