PubMed Central Journals
PMC is a free full-text archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM).
Most professional journals automatically deposit NIH funded manuscripts into the PMC system. Check the PMC System to determine if your journal participates in this service. If your journal does not participate in this service or you did not include NIH funding information before publication, the NIH Manuscript Submission system has information on manually depositing a publication in PMC.
