JAIRO (Japanese Institutional Repositories Online; http://jairo.nii.ac.jp/) is a union database for Japanese Institutional repositories which serves as an electronic archive system for research institutions. Through the database scholars can access some full-text journal articles, theses, dissertations, departmental bulletins, research papers, etc. from academic institutions such as universities and research institutes. The National Institute of Informatics (NII) provides this service and most of the full-text articles are free to the public. Please note, however, this database does not encompass commercial journals. For these kinds of materials we still have to use citation databases like Magazine Plus, and then check to see if the library owns a particular publication.
