Post-publication discussions and corrections

Journals must allow debate post publication either on their site, through letters to the editor, or on an external moderated site, such as PubPeer. They must have mechanisms for correcting, revising or retracting articles after publication

Our core practices

Core practices are the policies and practices journals and publishers need, to reach the highest standards in publication ethics. We include cases with advice, guidance for day-to-day practice, education modules and events on topical issues, to support journals and publishers fulfil their policies.

The tortuous tale of a paper, a letter and an editorial


Dr A submitted an article to journal X that was published in 1996. Dr B wrote to the editor in January 1997, pointing out an error by Dr A. Shortly afterwards, Dr B submitted a longer editorial to the journal discussing the issue raised by this error in a much wider context.


Attempted redundant publication?


Seven authors sent us a paper on hospital infections in children. We sent the paper to two reviewers, one of whom sent back a detailed comparison between the paper submitted to us and a paper published in another journal in 1996. The reviewer’s comments were:


Disagreement between a reviewer and an author


We sent a paper to a reviewer, who suggested that we should reject the paper, principally because he thought it “virtually identical to a paper in press by the same authors”. We rejected the paper with these comments. The author came back to us saying that he did not believe that he had had a fair review of his paper because, he thought, the reviewer had a conflict of interest.
