All journals should have a policy defining authorship - here's what to include

Scientific research papers with large numbers of authors have become more commonplace, increasing the likelihood of authorship disputes. Danielle Padula, Theresa Somerville and Ben Mudrak emphasise the importance of journals clearly defining and communicating authorship criteria to researchers. As well as having a policy for inclusion, journals should also indicate unethical authorship practices, clarify the order of authors at an early stage, consider recognising “contributorship”, and refer any disputes that do arise to the authors’ institutions.
