N – PLoS ignores impact factors

The Public Library of Science (PLoS) has decided “to stop promoting journal impact factors on our sites altogether. It’s time to move on, and focus efforts on more sophisticated, flexible and meaningful measures.” The statement, published on the PLoS Blog, follows the release of the 2008 impact factor data, showing significant increases for all PLoS’s journals. But PLoS believes that individual article metrics are a more useful measure of the impact of published science and better reflect the way scientists access published research.
