I'm getting copies of this for all the girls and women in my family. I knew about many of the women, but I didn't know some of the details of their contributions and sacrifices. Each biography is a 1-page essay with a timeline and photo on the opposite page. Many of the women in American history. They did a good job of mixing fields of study and race, though it was heavily weighted with suffragists. They only featured women who are dead, so contemporary women are not included.
There were some important women missing as well: Sacajawea, Wilma Mankiller, Betsy Ross, Dolly Madison, etc., but that is just opportunity for a second volume.
