Niigata University Academic Repository

What is an academic repository?


One of the aims of Niigata University is "to contribute to the further development of the region by co-operating with local communities and applying the results of its research to them". In order to meet accountability requirements demanded to universities in recent years, and as a part of industrial-academic co-operation and contribution to local communities, NUAR (Niigata University Academic Repository) was introduced.

"Repository" means "storehouse" or "treasure house". Research institutions like universities perform various kinds of educational and research activities, producing vast amount of valuable academic articles and materials. The system where these research outputs are preserved in digital forms on a server and freely accessed through the Internet is called an "Academic (Institutional) repository". Construction of the system is going on mainly in Europe and North America. In Japan, major universities have launched institutional repositories.


Because of the increase of the price of academic publications in recent years, most universities have no choice but to stop the subscription of some journals, which results in the decrease of the number of subscribers, which in turn leads to the further increase of subscription price. In this circumstance, it is becoming more and more difficult to access academic papers, and even if a scholar puts his or her articles in academic journals, they are not used effectively.

In order to break this situation, Open Access Movement for academic information began in 1990's. In 2002, as a new strategy against high subscription prices for scholarly journals of commercial publishers, Association of Research Libraries (ARL) of North America introduced the concept of an "institutional repository". It called for the construction of repositories, and they have gradually spread.

In Japan, "The 3rd Science and Technology Basic Plan" refers to the necessity of the open-access of research outputs after a certain period. "The future of Science Information Infrastructure (report)" by the Science and Technology Council of Ministry of Education, Culture, Sports, Science and Technology clearly mentioned that it is necessary to take positive action to construct institutional repositories. National Institute of Informatics launched a collaborative program for institutional repositories with universities to construct the "Next-generation scientific information resources infrastructure".


Academic repository is a new base for information dissemination.
By contributing research outputs to it, you can get many merits.

Following OAI-PMH, an international standard protocol for metadata harvesting, the information to be used for retrieving articles (metadata) is attached to each record of the repository. As a result, the records can be retrieved by many search engines like Google, and also by nation-wide or world-wide databases like JAIRO of National Institute of Informatics and OAIster of the University of Michigan. Thus, institutional repositories can disseminate information much more effectively than personal web sites.
