Universities and NII jointly work for various scholarly contents to realize the next generation scholarly content infrastructure. Institutional repositories are to serve for acquiring, organizing, preserving, and disseminating such scholarly information. They are a set of services by academic institutions for their academic communities to manage and publish digital contents they create.
To amplify the current content services and develop the next generation scholarly content infrastructure, NII supports for universities in Japan to introduce and operate institutional repositories.
NII conducted a pilot project with 19 universities in 2005 ; in 2006, NII entrusted a full-fledged project of IR promotion to 57 universities selected among 77 applicants; and in 2007, the project was extended with additional 13 universities.
