National Diet Library

Provides services that enable integrated search of bibliographic data and digital archives of prefectural libraries, archives, museums, institutes of academic research and NDL.

• NDL Search

Image database of the books held by the NDL and published in the Meiji, Taisho and early Showa eras, excluding books in Western languages.

After copyright clearance, the following classes of books are available on the Internet.

1. Books whose copyright has expired
2. Books whose copyright holder permits NDL to show them on the Internet
3. Books licensed by the Commissioner of the Agency for Cultural Affairs

The rest which do not have copyright clearance are available only inside the NDL (Tokyo Main Library and Kansai-kan).

• Digital Library from the Meiji Era(Japanese only)

"Rare Books Image Database" was moved to "Digitized Contents (Rare Books, etc.)<Japanese only>" on April 4, 2011.

You can search and read digital contents such as images previously provided by the "Rare Books Image Database" and publications collected from the Internet.
Contents digitized by the NDL Digitization Project and others are scheduled to be added.

The Historical Recordings Collection provides valuable sound sources such as music and speeches from Japanese records such as 78-rpm records from the early 1900s to around 1950, which have been digitized by the Historical Records Archive Promotion Conference (HiRAC) since FY2009.
The National Diet Library plans to increase the contents and provide them on-site. Contents in the public domain are to be open to the public on the Internet.
