We hear you

Last year, we came to the realization that online supplemental material had gotten out of control. In our conversations with authors and referees, we heard that the time needed to produce it and thoroughly review it was increasing at an unsustainable pace. In response, we changed our policy on supplemental material. Well, we’re still listening. And we’re hearing author frustration with seemingly endless rounds of external review at high-impact journals. We want to let you know that the editors of The Journal of Experimental Medicine have been working hard to avoid contributing to this problem.
