From the National Diet Library:
The East Asia Digital Library (EADL), a portal site for cultural and scientific resources in East Asian languages, was launched on December 17, 2020. Configuration and operation of the EADL is being performed by the National Library of Korea (NLK) with the cooperation of the National Diet Library (NDL).
The EADL is unique in that it allows integrated searches of historical materials in the Chinese, Japanese, and Korean languages held by either the NLK or the NDL. Both libraries have provided metadata for roughly 4,000 historical materials, and at present some 8,000 items are available in digital form. In addition to simple keyword searches, users can perform advanced searches by title, creator, or subject matter. Additional items will be added as they become available.
In addition to viewing digitized images of most materials by clicking a link to the digital platform of the host library, users can also enjoy browsing an online exhibition entitled the East Asia Digital Library Collection, which can be displayed chronologically or by subject matter. Additionally, metadata for EADL content is available via an EADL API service, which allows users convenient access to data for easy use in other systems or applications.
Please enjoy the rich academic and cultural resources of East Asia via the EADL.
