It Ain't Equal Until its Equal is the topic of Elizabeth Moon's blog, following press coverage of ArmadilloCon in Austin, TX last weekend. As writers of SFR, trying to raise the profile of our genre, this blog is of interest, IMHO. And she does a great job of breaking it down.
She also references this article about gender bias. I know Sisters in Crime was formed to combat gender bias in mystery reviews and they track the number of women's books reviewed of the majors, comparing them to ones for men's books. Raising the profile did help some through the years, though I believe in the last few years, as review outlets shrank, so did reviews for women's books.
This is an important topic for us, since it is our gender AND our fiction getting dismissed or diminished.
