Japanese National Diet Library: Home

The National Diet Library (NDL) (国立国会図書館, Kokuritsu Kokkai Toshokan) is the national library of Japan and among the largest libraries in the world.

What is the National Diet Library?

The National Diet Library Digital Collections are a treasure trove of rare and hard-to-find materials at the National Diet Library, Japan. Patrons at partner libraries subscribing to the Digitized Contents Transmission Service (such as UCC Library) are able to search and browse more than 2 million books, periodicals, rare books and old materials in the NDL’s Digital Collections, including about half a million materials which can be viewed online.

The Digitized Contents Transmission Service for Libraries is provided by the National Diet Library, Japan (NDL) as a means of making digitized versions of out-of-print, or otherwise difficult to-obtain, materials available to the general public at public or university libraries that subscribe to the Service.

The service enables UCC staff and students to:

  • Browse more than 1.5 million digitized materials from the NDL free of charge 
  • Access many periodicals and old books that are not available via the ILL service
  • Access services without time restrictions due to mailing or loan period
