In January IDW is releasing a special anthology of Women in Comics. Thanks to Bleeding Cool for the heads up.
That's not all though. As the article states, Diamond is pushing all kinds of women creators/artists and more at the same time for January.
Women write about comics is a special blog crossover that will be highlighting all sorts of issues about women in comics and sexism. (KP will not currently be taking part, but strongly endorse it nonetheless.)
The Guardian in the UK has also got an article up focusing on women in comics. It's about an upcoming experimental book that has an all male cast of writers but an all female cast of artists. The book is called Bayou Arcana.
