In support of open access to the journal literature, the U.S. NLM established an online library of digital journal articles, PubMed Central (PMC), which will soon be supplemented by a UK version. NLM works with the National Network of Libraries of Medicine (NN/LM) to provide regional medical library support in the United States, while its consumer health information service MEDLINEplus offers free access to health information, images, and interactive tutorials. Many countries like Australia, Canada, and the United Kingdom have well-developed medical libraries, though nothing quite as evolved as the U.S. NLM.
