Open or Closed?

Public access to scientific research is still being debated by the US House of Representatives, reports ScienceInsider's Jocelyn Kaiser. At a House Science Committee panel hearing, witnesses discussed whether the government should require federally funded research be made available to the public. "The most-discussed such mandate is that of the National Institutes of Health," Kaiser says. "Since 2008, NIH has required its grantees to post their peer-reviewed manuscripts in a free online archive after an embargo of up to 12 months following a paper's publication in a journal." At the hearing, the American Society of Plant Biologists' Crispin Taylor and the American Institute of Physics' Frederick Dylla said an NIH-style mandate would lead to widespread journal subscription cancellations, even with a 12-month embargo. On the other side, proponents argued that the NIH policy was a good model, and that other agencies should start with it and remodel the details to fit their needs, Kaiser adds.
