Open Access gives researchers the possibility of making their publications freely available on the internet. The philosophy behind Open Access is to make research freely available to the public and promote collaboration between universities and the business community.
If, as a researcher, you choose to publish via Open Access, your copyright on the work is not affected.
Aarhus University also encourages researchers to publish their work as Open Access.
The existence of multiple authors should not present an obstacle when uploading a post-print of an article from a journal. But it does require that the journal makes it possible AND that consent is obtained from all authors.
Uploading a post-print, and publishing an article, require the consent of all authors of the article in question, see section 2 of the Danish Copyright Act. When there are several authors of an academic article, there is a presumption that all authors are copyright holders of the article, see section 7(1): “If not otherwise stated the person whose name or generally known pseudonym or signature is indicated in the usual manner on copies of the work, or where the work is made available to the public, shall be deemed to be the author.”
There are no formal requirements for this consent, and the authors may give a single author the right to represent them in this regard. This is what usually happens when a journal requires a single author to be designated as “corresponding author” (although good practice among many journals prescribes that, even though there may be one corresponding author, all co-authors should still give their consent for publication directly to the journal).
The Vancouver Recommendations (ICMJE) The Vancouver Recommendations for authorship, "The Uniform Requirements", have been developed by The International Committee of Medical Journal Editors (ICMJE) and is recognized by 600 medical journals. Authorship is defined in the recommendations, and clear criteria for co-authorship are given, which the individual researchers should follow. Read the most recent recommendations regarding authorship. The Vancouver Recommendations also include other guidelines, such as the declaration of a conflict of interest.
If one of the writers gives consent to OA publication - consent is given on behalf of all authors, and the author should be aware that they are acting on behalf of the author group. It must be clearly stated that the author giving consent, has done so on behalf of the entire group. As Any person who acts as an agent on behalf of another person warrants that he has the necessary authority. [Translation of section 25 of aftaleloven, the Danish Contracts Act], when an author gives consent, it is on behalf of the entire author group. If there should be any problems in relation to a co-author, it is recommended that the article be removed from OA publication.
All authors should be named, in accordance with good practice.
