Barry Graubart writes about Nature‘s peer-review trial at his Content Matters blog. Mr Graubart refers to the Wall St Journal’s erroneous comment that Nature has “cancelled” the trial. As explained in the Nature report , the trial was originally intended to be a three-month experiment starting in June. In the event, we extended it by a month, closing it to new submissions in October. Since then, the remaining manuscripts in the trial have completed the peer-review process and we have been analysing the results (which necessarily meant waiting until the final manuscripts had received referees’ reports and could be removed from the trial).
