On October 27, a new web service "Newly Acquired Books Information" was released.

It enables you to get text files (TSV) of the basic bibliographic information of newly published books in Japan (including foreign language books), acquired under the legal deposit system of the National Diet Library. The data will be posted a few days after deposit.

For more information on the content of the data, how to download, etc., please see the guide page of "Newly Acquired Books Information".
