PMC is the new official name for PubMed Central, the National Library of Medicine's free online repository for scientific articles resulting from NIH-funded research. The name change should reduce confusion with NLM's MEDLINE search service called PubMed. When you do a search in PubMed you will see a link to any results available in PMC indicated by the note "Free PMC Article" in the listing. You can also search directly in PMC.
"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."
Remember if you would like to see PubMed results that show an icon for the materials we have, bookmark our custom PubMed URL.
