The history of the internet is often overfocused on the grandfathers who created its architecture and protocol. But the internet is more than a network of cables, servers, and computers—it is an environment that shapes and is shaped by its inhabitants and their use. In Cyberfeminism Index, a variety of hackers, scholars, artists, and activists consider how humans might reconstruct themselves by way of technology through more than 700 short entries of radical techno-critical activism. Both a vital introduction for laypeople and a robust resource guide for educators, Cyberfeminism Index—an anti-canon, of sorts—celebrates the multiplicity of practices that fall under this imperfect categorization and makes visible cyberfeminism’s long-ignored origins and its expansive legacy.
