Starting in less than a month, on April 7, 2008, scientists receiving grant money from the NIH must submit copies of their articles that are accepted for publication to PubMed Central. The papers in PubMed Central will be freely available to the public no later than 12 months after publication.
Also, starting May 25, 2008, all NIH applications, proposals, and progress reports must include the PubMed Central reference number when citing an article that falls under the policy.
Check out the NIH Public Access Policy page, which details how to comply.
