Ferguson C, Marcus A, Oransky I. Publishing: the peer-review scam. Nature 2014;515:480-482

Some observers argue for changes to the way that editors assign papers to reviewers, particularly to end the use of reviewers suggested by a manuscript's authors. Journal editors are trying to plug the holes.
