The Japanese National Bibliography (JNB)

• 国立国会図書館の書誌データ (Bibliographic data of the National Diet Library) (PDF: 1.95MB) (pamphlet in Japanese)

The Japanese National Bibliography (JNB) comprises standard bibliographic data for Japanese publications acquired via the legal deposit system as well as Japanese publications and foreign publications in Japanese acquired through donation, purchase, or other means.

The JNB includes print publications and packaged digital publications such as CDs and DVDs published in Japan as well as foreign publications in Japanese. Cataloging is usually completed within one month of acquisition. More than 95% of the printed monographs available commercially in Japan are recorded.

Also included are numerous publications with limited public circulation from national and municipal governments.

Bibliographic data for online publications acquired by the National Diet Library (NDL) since July 1, 2013, is available from the page "全国書誌（電子書籍・電子雑誌編） (Japanese National Bibliography Records of e-Books and e-Periodicals)" (in Japanese). The NDL acquires domestic Japanese online publications.

Newly arrived (in-process) records become searchable in Web Japanese National Bibliography about four days after acquisition, not including materials in Asian languages and maps.

* Downloading from the bibliography details screen, the search results list screen and the favorites screen is also available (including data other than national bibliographic data).
** The favorites screen is shared with NDL Search.
