Integration of the NDL Online and NDL Search web services

The National Diet Library, Japan, (the NDL) plans to integrate two of its current web services: the National Diet Library Online Search and Request Service (NDL Online) and the NDL Search. These two will be launched as a new NDL Search web service in January 2024.
Information about the new NDL Search can be found on this page.
This is where we will publish information on things to keep in mind about the system switchover as well as up-to-date information on temporary suspension of services.
