Topic page about publishing | Publishing with open access


Self-archiving involves uploading a full-text version of a research work to make it available in an open access institutional repository. At NTNU, the institutional repository is NTNU Open. 

As an author, you are obliged to upload a full-text version of research publications in Cristin as soon as possible after publication to ensure open access. Self-archiving in NTNU Open has been adopted in NTNU’s Guidelines for Policy for Open Science.

NTNU’s Rights Retention Strategy (in effect from 1 October 2022)

NTNU’s Rights Retention Strategy ensures that researchers at NTNU can always use self-archiving to make the final version of their peer-reviewed, accepted manuscript openly available (Green OA) without an embargo, regardless of any restrictions on the publisher’s part.

As a researcher, you also keep the copyright to your work, while NTNU takes on the legal responsibility for dissemination via the repository. You do not need to inform the publisher.

NTNU’s Rights Retention Strategy applies to research articles published after 1 October 2022.

The strategy is in line with the requirements from research funders such as the Research Council of Norway and the EU (Plan S). Researchers who do not have such requirements from external funders have the right to opt out of open access in the repository. Send an email to and specify the title of the article and the Cristin record code.

With the scheme, NTNU wants to contribute to the national goal of open access to results from publicly funded research by 2024.

Self-archiving step by step

  1. If you have published with open access (Gold OA), you use the final version published by the publisher (the Version of Record).

    If you have published in a closed channel (i.e. without OA), you use the final version of the accepted manuscript. Label the accepted manuscript (for example, on the title page or as a header/footer):

    “Author Accepted Manuscript version of the paper by [Author] in [Journal], Vol (Year), DOI”

    The Author Accepted Manuscript for articles published after 1 October 2022 must also be labelled:

    “Distributed under the terms of the Creative Commons Attribution License (CC BY 4.0)”
  2. Log on to Cristin and search for your articles.
  3. Find the relevant article and click on the number before it in the list - you will then see a screen with details about the article. If it does not appear in the list, you must register the article from scratch.
  4. Click “Submit full-text document” at the bottom of the screen.
  5. Specify the version you are submitting and upload the relevant file as a PDF. 6. The NTNU University Library publishes the full-text documents continuously in NTNU Open to make them available through open access. You can find a more detailed description here: self-archiving in Cristin.

Frequently asked questions

Does the Rights Retention Strategy apply from the date that the article is accepted?

No, the Rights Retention Strategy applies from the date that the article is published in the journal, and only for articles published after 1 October 2022.

What about articles that were published before 1 October 2022 and are under embargo – will this be lifted because of the Rights Retention Strategy? ?

No, the strategy only applies to articles published from 1 October 2022. For articles published before this, any embargoes will still apply.

Do I still have to sign the publisher's licence agreement, which only allows self-archiving after an embargo period?

Sign the agreement and upload the final version of the Author Accepted Manuscript to Cristin/NTNU Open. The embargo does not apply because of NTNU’s Rights Retention Strategy.

What is the difference between the Author Accepted Manuscript and the version of record published by the publisher?

The Author Accepted Manuscript does not have the journal’s layout and logo, but in other respects the content is identical to the published version.

How do I get hold of the Author Accepted Manuscript?

Contact the corresponding author, who should have received the manuscript from the publisher.

Does the Rights Retention Strategy also apply to monographs?

At this stage, it only applies to articles, because these are covered by the requirements of the Research Council of Norway, the EU, and other research funders.

What happens if the journal “complains”? Who should you contact?

Contact the University Library by emailing

Does the Rights Retention Strategy also apply when someone outside NTNU is the corresponding author?

NTNU’s employees have a duty to self-archive all their publications in the NTNU Open repository. You can apply to opt out of open access in the repository if it creates disagreement with the corresponding author and if the research funders of the publication do not require open access.

Can one disseminate the article anywhere? Not only in NTNU Open?

The final version of the Author Accepted Manuscript (for an article published after 1 October 2022) must first be uploaded in NTNU Open under a CC BY licence. The text will then be protected under the Rights Retention Strategy and can be disseminated anywhere.
