Women as academic authors.

This interactive infographic shows what percentage of authors across disciplines are female. The data span from 1665 to 2010. The data can be viewed as All Authors, First Authors/Solo Authors Only, or Last Authors only.  It's interesting to see the disparities across disciplines, as well as how the size indicators change when you move from the All Authors to First Author Only metric. As the main determinant of success in academia, this chart suggests we still have a long way to go.
