Why do we publish? As the editor-in-chief of a medical journal, I struggle a lot with this question. After more than 200 years, peer-reviewed journals have clearly established themselves as medicine’s best arbitrator of truth. They are, or at least ideally should be, at the center of everything we practice in our clinics. Yet somehow we physicians, even those of us in academia, are blind to many of the important roles that journals serve in medicine today.
