  • Over 1.9 million articles are available in PMC. (Expected to hit 2 million by end of June '10);
  • Participating journals: 640 full participants; 220 that participate through the NIH Portfolio; 880 titles who provide "selective deposit" to PMC (i.e. through author-pays model);
  • In a single month (March 2010) over 20 million articles were downloaded;
  • Over a period of 12 months (2009) 98% of content in PMC was accessed at least once; 69% of the articles were accessed 10 times or more (see image above).
