What have I gleaned? Le Guin, Butler, Russ and Tiptree Jnr were often cited. I've been utterly adoring the Tiptree collection and should probably be getting into these other collections. But there were quite a lot of other women cited - again, mostly from the women asked here. And Jeff. But I think I need to hunt up the Link and also that one called The Girl in the Flammable Skirt cause it sounds like fun.
