Citations

Research and non-research articles must cite relevant, timely, and verified literature (peer-reviewed, where appropriate) to support any claims made in the article.

You must avoid excessive and inappropriate self-citation or prearrangements among author groups to inappropriately cite each other’s work, as this can be considered a form of misconduct called citation manipulation. Read the COPE guidance on citation manipulation.

If you’re the author of a non-research article (e.g. a Review or Opinion) you should ensure the references you cite are relevant and provide a fair and balanced overview of the current state of research or scholarly work on the topic. Your references should not be unfairly biased towards a particular research group, organization or journal.

If you are unsure about whether to cite a source you should contact the journal editorial office for advice.
