Facebook's chief operating officer, Sheryl Sandberg, has a book coming out. And no, it's not a tell-all about the company's botched IPO.
It may actually be more interesting than that. The book, titled "Lean In," examines why there is a dearth of women in leadership positions throughout the world, and what steps we as a society and individuals can take to balance out the numbers a bit.
Sandberg has spoken about the topic many times -- most notably in the 2010 TED Talk "Why We Have Too Few Women Leaders," which has been viewed 1.7 million times.
The numbers she laid out in the talk are disheartening: Out of 190 heads of state in the world, only 9 are women. In the corporate world only 15% to 16% of the top jobs are held by women, and even in the nonprofit world, women have only 20% of the top jobs.
