CiNii (/ˈsaɪniː/)[1] is a bibliographic database service for material in Japanese academic libraries, especially focusing on Japanese works and English works published in Japan. An early trial version of the database was a component of its predecessor called GeNii, [2] available online at least since June 2002.[3]
A complete version of CiNii has been available since April 2005.
As of March 2020, the database contains more than 22 million articles from more than 3,600 publications.[5] A typical month (in 2012) saw more than 30 million accesses from 2.2 million unique visitors,[6] and is the largest and most comprehensive database of its kind in Japan. Although the database is multidisciplinary, the largest portion of the queries it receives is in the humanities and social sciences field, perhaps because CiNii is the only database that covers Japanese scholarly works in this field (as opposed to the natural, formal, and medical sciences which benefit from other databases).[7]
Database identifiers
The database assigns a unique identifier, NII Article ID (NAID), to each of its journal article entries.[6] A different identifier, NII Citation ID (NCID or 書誌ID) aka NACSIS-CAT Record ID, is used for books.
NCID examples
- NCID BA04004867 for the 1951 Little, Brown edition and of The Catcher in the Rye
- NCID BB17611495for the 2010 Penguin edition of The Catcher in the Rye
- NCID BA61718322for a 2003 edition of Kyatchā in za rai (キャッチャー・イン・ザ・ライ), all three being Japanese translations of The Catcher in the Rye
- NCID BB13715590for a 1997 edition of Mai tian li de shou wang zhe (麦田里的守望者), a Chinese translation of The Catcher in the Rye.
Identifiers are also assigned to authors of books, and of journal articles, in two separate series (so an author may have a different identifier value in each). For example, Shinsaku Kimoto is DA00432173 for books and 9000002393144 for journal articles.
