The Japanese National Bibliography (JNB)

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 since July 1, 2013, is available from the page "全国書誌(電子書籍・電子雑誌編)TSVファイル一覧 (Japanese National Bibliography records of e-books and e-periodicals in TSV format)" (in Japanese). The National Diet Library acquires domestic Japanese online publications that are available free of charge and without Digital Rights Management (DRM).

Newly arrived (in-process) records become searchable in the NDL Search about four days after acquisition, not including materials in Asian languages and maps.
