New NDL Search

The National Diet Library has integrated two of its web services—the National Diet Library Online Search and Request Service (NDL Online) and the NDL Search—and launched them as the new NDL Search web service on January 5, 2024.
This page provides information about the new NDL Search. (Last updated January 5, 2024)

1. Functions for Searching and Requesting

Patrons can search for NDL library materials and digital content as well as apply for a variety of services. They can also search bibliographic and holding information for books at prefectural and government-designated city libraries or search for library materials and digital content available from public, university, and specialized libraries as well as academic research institutions in Japan, all via a single web service.

2. Providing information in support of the desire for knowledge

Search results in the new NDL Search include information that is useful for research. Using reference information provided by the Research Navi and Collaborative Reference Database, the new NDL Search supports our patrons' desire for efficient access to a wide range of information.

3. A new and improved user interface

A newly redesigned interface makes all our services easier to use for both new and experienced patrons. Improved usability and accessibility make it easier to use digital content, including the National Diet Library Digital Collections, from the new NDL Search.

Use from smartphones or tablet devices

The new NDL Search makes it easier to see search results, browse digital content, and request services from smartphones and tablet devices. Also, when visiting the Tokyo Main Library, the Kansai-kan, or the International Library of Children's Literature, patrons can request to browse materials in the stacks and check the request status from their own smartphone, tablet device, or PC, making it convenient even when the library is crowded.
