Changes in authorship: Addition of extra author – after publication

COPE's guidance, as a flowchart, on Changes in authorship, Part (c) A request is received for the addition of an extra author after publication.

To prevent future problems:

1. Before publication, get authors to sign statement that all listed authors meet authorship criteria and that no others meeting the criteria have been omitted.
2. Publish details of each person’s contribution to their search and publication.
