The Woman's Signal was a weekly British feminist magazine published by Marshall & Son, London, from 4 January 1894 to 23 March 1899.  It was edited by Lady Henry Somerset, Annie Holdsworth and Florence Fenwick-Miller.  Although primarily a temperance paper, it dealt with several feminist issues including fair wages.

A comic book letter column is a section of an American comic book where readers' letters to the publisher appear.  Comic book letter columns are also commonly referred to as letter columns (or lettercols), letter pages, letters of comment (LOCs), or simply letters to the editor.  Letter columns appeared early on in the history of comic books themselves, and their growing prevalence — particularly beginning in the 1960s — helped create and legitimatize comics fandom.  Letter columns remained a regular feature of most comic books until the early years of the 21st century, when they were gradually phased out in favor of the growing prevalence of email and Internet forums.

The Barnard Conference on Sexuality is often credited as the moment that signaled the beginning of the Feminist Sex Wars.  It was held at Barnard College on April 24, 1982, and was presented as the annual Scholar and Feminist Conference IX, an integral part of the Barnard Center for Research on Women.  The theme of the Conference was Sexuality.  The Conference was set up as a framework for feminist thought to proceed regarding topics that many felt uncomfortable talking about.  As Carole Vance, the Academic Coordinator of the Conference wrote in her letter inviting the participants “sexuality is a bread and butter issue, not a frill.” Chrysalis: A Magazine of Women's Culture was a feminist publication produced from 1977 to 1980.  The self-published magazine was founded by Kirsten Grimstad and Susan Rennie at the Woman's Building in downtown Los Angeles.  "Chysalis" grew from Grimstad and Rennie's editorial work on the self-help resource books, The New Woman's Survival Catalog and The New Woman's Survival Sourcebook.  "Chrysalis" distinguished itself from other feminist publications through an organic integration of politics, literature, cultural studies, and art.  The magazine was produced through a collective process that grew out of the feminist practice of consciousness-raising.  Unusually broad in scope, "Chrysalis" did not substitute breadth for quality.  The authors, poets, essayists, and researchers contributing to the magazine reveals a veritable who's who of towering intellects of the feminist movement: black lesbian activist Audre Lorde; the magazine's poetry editor, Robin Morgan, who later served as editor of Ms. from 1990-1993: award winning poet Adrienne Rich; novelist Marge Percy; artist Judy Chicago; science fiction writer Joanna Russ; art critic Lucy Lippard, plus Mary Daly, Dolores Hayden, Andrea Dworkin, Marilyn Hacker, Arlene Raven, and Elizabeth Janeway.  Over a three-year span, the all volunteer staff produced ten issues before they were forced to disband in 1981 due to financial difficulties.
