Do you have NIH funding? Then read this.

In the "Policy on enhancing public access to archived publications resulting from NIH-funded research," the NIH requests that all publications resulting from primary research supported by NIH grants be deposited in PubMed Central (PMC), the online repository of the National Library of Medicine. The NIH requests that all manuscripts accepted for publication after May 2, 2005 be deposited in PMC, and that those manuscripts be made freely available to the public within 12 months of publication. The JCI supports this policy: we will continue to make all content freely available in PMC immediately upon publication, and the entire JCI archive is freely available through PMC.
