What is Open Access?

Open access is where research literature is published free to read online, with a clearly identifiable reuse license. Open Access is a key tool aimed against the rapidly rising costs of journal subscription prices, and at the same time accelarates interdisciplinary research and innovation, resulting in more research output taken up by society.

Authors also merit from making his/her research output open access. Open access articles have a greater potential readership, meaning they recieve more access, resulting in higher numbers of citations. Authors are also able to read their articles anytime, anywhere via the internet.

Open Access is now a global movement. In the United States, the National Institute of Health(NIH) issued a Pulic Access Policy in 2008 which mandates research papers describing research funded by the National Institutes of Health to be available to the public free through PubMed Central within 12 months of publication. In the UK, the RCUK also issued an Open Access Policy in 2012 stating all research which acknowledge Research Council funding allow “immediate, unrestricted, on‐line access to peer‐reviewed and published research papers, free of any access charge and with maximum opportunities for re‐use." In Japan, funders have also requested that publicly funded research should be made available to the public free of charge.

How to acheive Open Access

There are 2 routes to making research output openly accessible:

Gold Open Access

Gold open access is when either the author or their institutions and funders pay an APC(Article Processing Charge) to publish an article in a fully open access journal or hybrid journal.

Green Open Access

Green open access is the practice of making a research output available by placing a version of an author’s manuscript into a repository. Researchers affiliated with Hitotsubashi University can make their research open by submitting to Hitotsubashi University Repository HERMES-IR.

What is an Institutional Repository?

An Institutional Repository is an archive for collecting and preserving digital copies of the research output of a research institution. Hitotsubashi University’s repository, HERMES-IR, collects and disseminates research materials published by its members once permission can be obtained. Our collections include Doctoral Dissertations submitted after 2013, departmental bulletin papers, working papers, University Archives, the Libraries special collections and more.
