UK PubMed Central (UKPMC) is now live and freely available at http://ukpmc.ac.uk Based on PubMed Central (PMC) <http://www.pubmedcentral.nih.gov/> , the U.S. National Institutes of Health free digital archive of biomedical and life sciences journal literature, UKPMC provides a stable, permanent, and free-to-access online digital archive of full-text, peer-reviewed research publications. UKPMC is part of a network of PMC International (PMCI) <http://www.pubmedcentral.nih.gov/about/pmci.html> repositories. PMCI is a collaborative effort between the US National Library of Medicine <http://www.nlm.nih.gov/> (NLM), the publishers whose journal content makes up the PMC archive, and organizations in other countries that share NLM's interest in archiving life sciences literature. The set-up, maintenance and ongoing development of UKPMC is being funded by Arthritis Research Campaign, The Biotechnology and Biological Sciences Research Council, The British Heart Foundation, Cancer Research UK, The Chief Scientist Office of the Scottish Executive Health Department, the Department of Health, The Joint Information Systems Committee, the Medical Research Council and the Wellcome Trust. UKPMC is a service of the UKPMC Funders Group working in partnership with the British Library, University of Manchester & the European Bioinformatics Institute. As of today the UKPMC database holds over 620,000 full-text articles - mirrored from PMC in the US, whilst the UK Manuscript Submission System [UKMSS] - which grantees can use when they need to self-archive their research papers - contains details of 15000 grants awarded to over 8000 grantees.
