(31 Jul 2020) As of January 2021, NDL bibliographic data will be available as described below.
Bibliographic data in JAPAN/MARC MARC21 format via NDL Search
The NDL will end its NDL-Bib service on December 28, 2020. In its place, individual bibliographic data in either MARC format or MARC tags format will be available for download from NDL Search results. Only bibliographic data created by the NDL will be available in these formats. As shown in the image below, download links will appear in the lower right-hand column of search results details when available.
Collaboration between Web NDL Authorities and NDL Online
Also in January 2021, patrons will be able to search bibliographic data in the NDL Online by clicking a link provided in the Web NDL Authorities. This replaces the function that is currently available in the NDL Search via the ID of the Authority data.
The original announcement is here.
