The NDL has launched an English-language user interface to its Web Archiving Project (WARP) on November 2, 2018. The entire user interface—including the search interface, help page, and FAQ—is now available in English.
WARP has been collecting and preserving websites since 2002. The entire archive of websites is available for viewing on the premises of the NDL. Archived websites for which the webmaster has granted permission are also available via the Internet from the NDL website.
