apanKnowledge Lib is an online web archive that boasts the largest corpus of encyclopedia, dictionaries, reference compilations, and periodical resources (approximately 50 different sources) in Japan. The basic search system that facilitates cross-referencing throughout all the sources in the collection is quite simple to use, but at the same time includes an original faceted navigation function for users to focus their particular searches in specific reference sources. This allows for greater detailed indexing.
This nine-volume reference contains over 10,000 articles exploring every aspect of Japanese society, history, politics, economy, thought and culture. The 50,000-item index is cross-referenced for easy location of facts.
