There are two PMC International centres: Europe PMC and PMC Canada. PMC International “is a collaborative effort between NIH and NLM, the publishers whose journal content makes up the PMC archive, and organizations in other countries that share NIH's and NLM's interest in archiving life sciences literature” (www.ncbi.nlm.nih.gov/pmc/about/pmci/).
