Co-authors, corresponding authors, and affiliations
A co-author is any person who has made a significant contribution to a journal article. They also share responsibility and accountability for the results. If more than one author writes an article, you’ll choose one person to be the corresponding author. This person will handle all correspondence about the article and sign the publishing agreement on behalf of all the authors. The corresponding author is responsible for ensuring that all the authors’ contact details are correct. You should all agree on the order in which your names will appear in the article. Please also ensure that your affiliations are correct, as explained below.
If you are a named co-author, this means that you:
- Made a significant contribution to the work reported, whether that’s in the research conception or design, acquisition of data, analysis and interpretation, or in all these areas.
- Have drafted, written, or revised the article.
- Reviewed and agreed the final version of the article before submission.
- Have agreed on the journal to which your article will be submitted.
- Are aware that you are taking responsibility and accountability for the content of the article.
- Are aware that the corresponding author will be acting on your behalf in any communication about the article, through submission, peer review, production, and after publication.
- Share responsibility with all named co-authors if your article is found to be unsafe, in error, in some way fraudulent, or in breach of the publishing agreement.
Affiliations: get it right
Your affiliation in the manuscript should be the institution where you conducted the research. You should also include details of any funding received from that institution. If you have changed affiliation since completing the research, your new affiliation can be acknowledged in a note. We can’t normally make changes to affiliation after the journal accepts your article.
- After the journal has accepted your article , if you need to change the co-authors for any reason you should write to the editor of the journal, with a clear reason for the change. This letter must come from all the authors, including the person you are adding or removing. The editor will need to agree to the change.
- If the corresponding author changes before the article is published (i.e., if a co-author becomes the corresponding author), please write to the editor of the journal and the production editor, confirming that both authors have agreed the change.
- Requested changes to the co-authors or corresponding authors after publication of the article will also be considered, following the authorship guidelines issued by COPE, the Committee on Publication Ethics. Please see our corrections policy for more details.
Agree your corresponding author and the order of co-authors, and check all affiliations and contact details before submitting.
