Extension of expiry date of user information is not available via NDL Online, etc. during the year-end and New Year's holidays

User registration of the National Diet Library is valid for three years from the date of registration. Each time you use the NDL's services, the validity period will be automatically extended to three years after the date you use them. After three years have passed from either the date of user registration, the last time you entered the NDL (either Tokyo Main Library, Kansai-kan or the Researchers' Reading Room of the International Children's Literature), the last time you logged into NDL web services or the date you used the Remote Photoduplication service (the date when the NDL accepted your request for the service), the user information will expire.

For the following patrons, registered user information may expire between the end of the year 2023 and the beginning of the year 2024.

• Patrons who registered between December 2020 and January 2021 and have not had the opportunity to use the NDL's services since then.
• Patrons who registered prior to December 2020 and between the end of the year 2023 and the beginning of the year 2024, it will have been three years since the last use of NDL services.

The NDL will be closed from December 28 (Thu.), 2023 to January 4 (Thu.), 2024 for the year-end and New Year's holidays. In addition, due to the system switchover, patrons will not be able to log in to NDL Online or NDL Search from 19:00, December 27 (Wed.), 2023, to January 4 (Thu.), 2024.
Since the National Diet Library Digital Collections is generally available during the system switchover, patrons can extend the expiry date by logging in to the National Diet Library Digital Collections. If you are unable to log in because you do not know your User ID or password, please note that neither can be reissued from 19:00, December 27 (Wed.), 2023, to January 4 (Thu.), 2024.

We recommend that patrons extend the expiry date of their user registration by following the instructions below by December 27 (Wed.), 2023.

Patrons can extend the expiry date by logging into the National Diet Library Digital Collections with their User ID and password.

(2) Extension of expiry date by logging into NDL Online or NDL Search

If patrons have lost their registered user card, it is necessary to have the card reissued before entering the NDL. Please remember to bring identification documents such as a driver's license.

If user information expires due to not following methods 1 or 2 above, the user information will be deleted. To use the service as a registered user, it will be necessary to re-register as a user.
