国立国会図書館典拠データ検索・提供サービス
Web NDL Authorities is a service by the National Diet Library (NDL), Japan, to access authority data created and maintained by the NDL. Name headings or Subject headings are assigned to the bibliographic data to distinguish different people with the same name or to identify people who use pseudonyms, nonstandard spellings, transliterated names, or other variants. To control these headings, authority data is organized to indicate alternative headings, synonyms, and the basis of choice for the headings.
