PubMed Central (PMC) is the U.S. National Institutes of Health (NIH) free digital archive of biomedical and life sciences journal literature, developed and managed by NIH's National Center for Biotechnology Information (NCBI) in the National Library of Medicine (NLM). All the articles in PubMed Central are free (sometimes on a delayed basis). Some journals go beyond free, to Open Access.
