Progress toward Public Access to Science

The National Institutes of Health (NIH) is about to cross an important threshold. Starting April 7th, the authors of research reports that describe work supported by the NIH will be required to deposit accepted manuscripts into PubMed Central (PMC), the NIH's public digital library of full-text articles, with the understanding that the articles will be freely available for all to view no later than 12 months after publication.
