The internet is not only a network of cables, servers, and computers. It is an environment that shapes and is shaped by its inhabitants and their use. Edited by designer, professor, and researcher Mindy Seu, Cyberfeminism Index includes more than 700 short entries of radical techno-critical activism, academic articles, hackerspaces, software education, net art, and more. Both a vital introduction for laypeople and a robust resource guide for educators, Cyberfeminism Index —an anti-canon, of sorts—celebrates and makes visible cyberfeminism’s long-ignored origins and its expansive legacy.
