Public (open) access policy.

The article offers information on the mandatory Public Access Policies introduced by the U.S. National Institutes of Health (NIH) and the British agency Wellcome Trust for all research papers. The NIH policy requires all investigators funded by the National Library of Medicine's PubMed Central (PMC) to submit an electronic version of their final manuscripts. The Wellcome Trust policy mandates electronic copies of any research papers accepted for publication to be made available through PMC.
