Integrated Retrieval System -NIHU

Six research institutes make up National Institutes for the Humanities: National Museum of Japanese History, National Institute of Japanese Literature, National Institute for Japanese Language and Linguistics, International Research Center for Japanese Studies, Research Institute for Humanity and Nature, and National Museum of Ethnology.
The over 100 databases that they provide can be collectively cross searched. In addition, with the space-time data that the individual databases provide, integrated retrieval and display functions have been achieved.
