It is more difficult to research women's lives than it is men's. There has always been a tendency - race notwithstanding - to believe that women's contributions have been less important than men's contributions because women are usually less public people.

When we look at women, we have to look at the significance of their work in a different way from the way we look at it with men. Women have more often worked within the home, working equally as hard, I would argue, but not always out there where they're counted, not always up there in the labor unions, certainly not in leadership positions.

For all kinds of reasons, it is more difficult to track women's lives. Women's words have simply been considered less important, so they have been preserved less often.
