In the field of journalism, it is common for sources to sometimes request a press embargo, meaning that they ask reporters to refrain from publishing information until a certain date or until certain conditions are met. In theory, this is reasonable. However, there are times when journalists perceive embargoes as overly restrictive and unnecessarily entangling. Medical journalist Ivan Oransky has created Embargo Watch to "keep an eye on how scientific information embargoes affect news coverage." Here readers will find the latest details on how famous journals like Nature, Science, the Lancet, PNAS (and many others) release information to journalists with the expectation that news reports will, at least usually, coincide with the publication of the articles in question. Things get interesting, of course, when some news outlets break embargoes, or when journals ask for embargoes that strike journalists as unreasonable. The blog entries on this site, which tend to be published monthly or as problems with embargoes arise, are insightful, incisive, and informative for anyone interested in how journalism works behind the scenes.
