If you want to have all the info about women and sf at you fingertips, I suspect you could do a lot worse than start with Women in Science Fiction and Fantasy, an encyclopedia in 2 volumes edited by Robin Anne Reid. For all the nifty contents, see Reid’s comments to a previous blog post, starting here.
Coming soon: a list of other non-fiction books on the topic that I’d love to own–and think you should, too. While I’m about other business, feel free to leave comments.
Some examples to get you started: In the Chinks of the World Machine, Sarah Lefanu, On Joanna Russ, Farah Mendlesohn, The Battle of the Sexes in Science Fiction, Justine Larbalestier.
