PubMed Central® (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). In keeping with NLM’s legislative mandate to collect and preserve the biomedical literature, PMC serves as a digital counterpart to NLM’s extensive print journal collection.

PMC was developed and is managed by NLM’s National Center for Biotechnology Information (NCBI).

Since its inception in 2000, PMC has grown from comprising only two journals, PNAS: Proceedings of the National Academy of Sciences and Molecular Biology of the Cell, to an archive of articles from thousands of journals.

Today, PMC contains more than 6 million full-text records, spanning several centuries of biomedical and life science research (late 1700s to present). Content is added to the archive through.
