Ethics of authorship
When determining the credit for a piece of work, authors should ensure that all those who have made a significant contribution are cited as co-authors. Other individuals who have contributed to the study in a lesser capacity should be acknowledged, but not cited as authors.
Some co-authors will be accountable for the entire article, for example those who provide critical data, write the manuscript, present the findings at conferences or provide leadership for junior colleagues. Other co-authors may be responsible for specific contributions to a paper. Where such specific attributions of credit and responsibility are required, authors must make this clear in the acknowledgements of the article otherwise all co-authors will be taken to share full responsibility for all of the paper. Authors should not use acknowledgements misleadingly to imply a contribution or endorsement by individuals who have not, in fact, been involved with the work or given an endorsement.
Responsibility of the corresponding author
It is the corresponding author’s responsibility to ensure that all named authors have approved the submitted version of the manuscript, agree to its submission and are willing to take appropriate responsibility for it.
All authors should be consulted about any subsequent changes to authorship (e.g. the list of authors) during the publication process, and it should be made clear to the journal that they have given their consent.
