Two Milestones for PubMed

The current issue of the NLM Technical Bulletin (published 9/10/10) celebrates two major milestones for PubMed and the National Library of Medicine.  First of all, PubMed indexed its 20 millionth citation earlier this summer on July 27.  On that same day, PubMed Central, the NIH free digital archive of biomedical and science literature, added its 2 millionth full text article.

The full article can be found here, as part of the NLM website, and offers a few more interesting details:  usage statistics indicate that over 1 billion PubMed searches are run each year!  Additionally, PubMed Central, which, again, offers access to free full-text articles, now offers articles from over 650 journals, and even includes historic collections from the 1800s (which should remind you of the expert research advice I gave earlier this week!).
