Editori Riuniti is an Italian publishing house based in Rome that publishes books and magazines on the history of socialism, socialist thought, physics and mathematics theory, and the history of Central and Eastern Europe and the Balkans.
Editori Riuniti began publishing its flagship magazines, which were initially edited by Bonchio and Gerratana until Bruno Munari contributed to their graphic design.
The publishing house also began important partnerships with European intellectuals like Maurice Dobb, Louis Althusser, Eric Hobsbawm, and Roberto Longhi.
In the 1970s, Editori Riuniti published the Opere complete di Marx e Engels and the 11-volume encyclopedia Ulisse, under the direction of Lucio Lombardo-Radice.
Editori Riuniti published the complete works of both Karl Marx and Friedrich Engels in Italian.
