Women don't cite themselves as frequently as men

The Chronicle of Higher Education has an interesting report showing that "even as citation rates become a key measure of productivity, 
women don’t refer to their own research nearly as often as men do." An analysis of 60 years of JSTOR articles shows that men are 56% more likely to cite their own scholarly work - and over the past decade, the figure is considerably higher, with men citing themselves 64$ more.
