Self-archiving in DUO via Cristin

UiO supports the government's goal that all Norwegian scientific articles financed by public funds should be open access to the public. To follow up the national guidelines for open access to research articles, and demands from EU and the Research Council, all articles should be archived in DUO.

How to submit your article:

  1. Keep an accepted version of your article. Contact the corresponding author if you do not have it yourself. See examples of accepted versions of articles.
  2. After you have published your article, search for it in Cristin and upload the accepted version, see instructions. Remember to be logged in to Cristin when doing this.
  3. The DUO-group at the University Library will check if the article can be published to DUO.
  4. If an embargo applies, the DUO-group will register that.
  5. If the final version can be made public, the DUO-group will make arrangements.

Remember: Does your article have a CC license? Then you can upload the final published version in Cristin. If not, upload the accepted version (AAM/postprint).

  • Published version, Version of record (VoR): the final published version with the publishers layout.
  • Pre-print, original manuscript, submitted paper: manuscript before it has been peer reviewed. This version can be ammended after the peer reviews.
  • Embargo: a time limit defined by the publisher on how long it must take before making the article available in a open archive. The embargo can apply for 6 to 36 months before the article can be made available in DUO.
  • Institutional archive / repository: An open electronic archive for collecting, preserving and distributing copies of the academic production in an institution.
  • Sherpa/Romeo is a database of publishers' guidelines for self-archiving. The database does not include all Norwegian journals and publishers. For information on book chapters, go to the publisher's website.

  • CC-license, CC BY, Creative Commons: open licenses describing an agreement between the author (the copyright holder) and the reader (the user). An article with a "CC BY Attribution"-license shows that the reader is granted a number of forms of use of the work, while the author retains the right to be named as the work's author (copyright holder).

More information about self-archiving

Self-archiving and sharing accepted version (AAM/post-print):

When the article has been accepted, save a post-print version of the article based on peer reviews.

According to the requirements from UiO and  the Research Council of Norway, this version must be uploaded via Cristin to DUO Research Archive. You can wait with uploading your article to Cristin until after the it has been published. Often the article will already be registered in Cristin, and you will not have to register information manually. Uploading the file can then be done quickly. The DUO-group at the University Library will check all uploads to DUO to make sure that only allowed versions are available.

May published version be shared and self-archived?

When the article has been published, you will normally receive a file containing the journal’s final, formatted version. It is not always allowed to self-archive this version in DUO, in subject archives or share on other websites. Check the journal’s website, your publishing contract or in the SHERPA/RoMEO database.

Why you can't archive published version

According to the Copyright Act, you as a writer have the rights to distribute and use texts and other material you have produced. However, when you publish scientific texts in books or journals published by commercial publishers, many publishers require you to sign an agreement that entails transferring the right of exclusive publishing to the publisher.

Rights that are often signed to the publisher include, for example, the right to reproduce, distribute and publicly display the article in any medium, and the right to authorize others to use your publication.

Other archives

In some subjects it is common to share the pre-print version in a subject archive such as arxiv or RePEc. Some publishers allow this and others do not. You can find out on the journal’s website. It might also be registered in the SHERPA/RoMEO database.

A lot of people also choose to share their research on social platforms such as ResearchGate or You should check the journal’s website to determine if this is allowed or not.
