ï¼Within minutes after the impact factors for 2009 being released, one could almost hear the sounds of champagne corks popping in San Francisco. Or were they the sounds of competing publishers banging their heads against their office walls in utter amazement? For there seems something very strange about a journal that accepts nearly 70% of all submissions yet achieves such a score, especially with its first assessmentï¼.

ï¼For anyone considering that PLoS ONE engaged in editorial shenanigans to boost self-citations, there is no evidence of such. Self-cites represent just 8% of the citations used to calculate their impact factor, and removing these self-cites drops their score to just 4.00. We must accept that this is a valid and correct measure of the citation impact of PLoS ONE articlesï¼.
