Printers and presses were central to the physical and social reproduction of the classical anarchist movement from the Paris Commune to the Second World War. Anarchists produced an environment rich in printed words by creating and circulating hundreds of journals, books, and pamphlets in dozens of languages. While some scholars and activists have examined the content of these publications, little attention has been paid to the printing process, the physical infrastructure and bodily practices producing and circulating this remarkable outpouring of radical public speech. This paper brings the resources of the new materialism into conversation with the networks of anarchist printers and presses. Printers and presses operated as nodal points, horizontal linkages among the objects, persons, desires, and ideas constituting anarchist assemblages. In their publishing practices, anarchists may have implicitly identified a constitutive condition of possibility for the flourishing of radical political communities in our time as well as theirs.
