IRDB is a database for materials stored in institutional repositories in Japan. Those that can be searched include articles published in departmental memoires and journals, dissertations and theses, and digitised rare books stored by individual institutions. This database is useful to search for materials other than articles: i.e., collections that are not provided through their own interface.
