RT Journal A1 Rivara FP, Brosco JP T1 The archives of pediatrics & adolescent medicine at 100: Another turning point in medical publishing JF Archives of Pediatrics & Adolescent Medicine JO Archives of Pediatrics & Adolescent Medicine YR 2011 FD January 1 VO 165 IS 1 SP 6 OP 8 DO 10.1001/archpediatrics.2010.263 UL http://dx.doi.org/10.1001/archpediatrics.2010.263 AB In January 1911, the inaugural issue of the American Journal of Diseases of Children (AJDC) (the original title for the Archives of Pediatrics & Adolescent Medicine) was published. Like many other specialty journals emerging at the time, the founding of AJDC was one part of an extraordinary transformation in American medicine. Periodic medical journals like AJDC, in contrast to textbooks, implied that new knowledge was constantly being produced and should be disseminated; specialty journals in particular reflected the growing complexity of medicine and the emergence of new practice patterns in American cities. In this essay, we review the historical context of the founding of AJDC, note some contrasts to today's journal, and speculate on the future of medical journals as medicine is again undergoing a radical transformation in practice patterns and the availability of medical knowledge.
