New impact factors for PLoS journals

From Mark Patterson, PLoS Director of Publishing, on the PLoS blog:

The 2006 impact factors have just been released by Thompson ISI. The first two PLoS journals continue to perform very well: 14.1 for PLoS Biology (14.7 in 2006); 13.8 for PLoS Medicine (8.4 in 2006). The PLoS community-run journals also received their first impact factors: 4.9 for PLoS Computational Biology; 7.7 for PLoS Genetics; and 6.0 for PLoS Pathogens. (Note that the latter impact factors are based on only around six months worth of publications in 2005, and are likely to increase next year.)
