PubMed Central® (PMC) is a free archive of biomedical and life sciences journal literature at the
U.S. National Institutes of Health's National Library of Medicine (NIH/NLM).
Free Access Archives
As an archive, PMC is designed to provide permanent access to all of its content, even as technology evolves and current digital literature formats potentially become obsolete. NLM believes that the best way to ensure the accessibility and viability of digital material over time is through consistent and active use of the archive. For this reason, free access to all of its journal literature is a core principle of PMC.
Please note, however, that free access does not mean that there is no copyright protection. As described on their copyright page publishers and individual authors continue to hold copyright on the material in PMC and users must abide by the terms defined by the copyright holder.
What is it?
PubMed Central® (PMC) supplies many full-text articles for citations found in a PubMed search.
PMC serves as a digital counterpart to NLM’s extensive print journal collection.
