The humanities cannot go public without publishing. In this contribution to the Manifesto issue of Public Humanities, Daniel Fisher-Livne, Kath Burton, and Catherine Cocks highlight the radically inclusive publishing practices necessary to support the Public Humanities ecosystem. The authors explain how Publishing and the Publicly Engaged Humanities Working Group activities have prepared the ground for future growth, directing attention to the inherently collaborative, multimodal and values-based publishing practices of engaged scholars. This paper builds on the central thesis of the Working Group, calling for the implementation of a radically inclusive ecology of publishing practices that embody and nurture the unique facets, connections and aims of publicly engaged publications.
