Depositing your work

How to deposit your work

  Though researchers should essentially control scholarly communication, each publisher has different policies concerning self-archiving. According to a self-archiving research project, most of publishers permit using the final draft post-referring version of their paper in institutional repositories. Start off by sending your article to the Library. After the Library confirms copyright policies, metadata, etc., the submitted article will be deposited to "naistar".

Self-archiving policies of publishers are available on the following sites.


  • The copyright of research material shall remain with the copyright holder, not being transferred to the Library when it is deposited to the repository.

What is the final draft post-referring version?

  • At each step of submission or revision of an article, there are different versions with author and publisher. The final draft post referring version is the final author's version which has been accepted by the publisher. This version will eventually formatted and released as "Publisher version" in online journals.
  • As many publishers permit using the final draft post-referring version of papers in institutional repositories, please keep them for future archiving.
