PLoS Biology has top impact factor of general biology journals

PLoS Biology is now old enough to have an impact factor. Quoting from today's press release: 'The open-access journal PLoS Biology has been assessed by Thomson ISI to have an impact factor of 13.9, which places PLoS Biology among the most highly cited journals in the life sciences. This is an outstanding statistic for a journal less than two years old, from a new publisher promoting a new business model to support open access to the scientific and medical literature. An impact factor of 13.9 places PLoS Biology above such established journals as EMBO Journal, Current Biology, and the Proceedings of the National Academy of Sciences. In fact, in ISI's category of general biology journals, PLoS Biology is ranked number 1....By any measure, the impact of this launch was impressive. The on-line publication of the first issue was accompanied by strong and favorable media coverage, and subsequent issues continue to receive regular attention. Content from PLoS Biology has been read, copied, redistributed, and reused, without restriction (aside from proper citation of the authors), and now we know that the journal has also been cited time and time again.'
