01-16-2013 The American Journal of Epidemiology is the premier journal for epidemiologists, but it is also aimed at public health professionals and clinicians. Each biweekly issue contains original research articles and epidemiology practice contributions. The journal is published on behalf of The Johns Hopkins Bloomberg School of Public Health and sponsored by the Society for Epidemiologic Research. The "Advance Access" feature on the publisher's web site allows for early access to papers that have been accepted but not yet paginated. This journal is essential for all academic medical and hospital library collections. URL: http://aje.oxfordjournals.org (Bobal, Alison)
