One of the best websites I've seen for celebrating women writers is called A Celebration of Women Writers. Among their many resources are special collections tagged to various themes. Right now the featured Special collection is for pre-1923 Utopias and Science Fiction by women. The online reading guide includes offerings by Margaret Cavendish, Duchess of Newcastle (1623-1673), African-American writer Pauline Hopkins (1859-1930), and Charlotte Perkins Gilman (1860-1935). Browse their extensive list of authors to meet more writers, many of whom have been forgotten or ignored.
