The foremost proponent of "propaganda by the deed" in the United States, Galleani was the founder and editor of the anarchist newsletter Cronaca Sovversiva (Subversive Chronicle), which he published and mailed from offices in Barre. Galleani published the anarchist newsletter for fifteen years until the United States government closed it down under the Sedition Act of 1918. Each issue of Cronaca Sovversiva usually had no more than eight pages. At one point the newsletter claimed 5,000 subscribers. It offered perspectives on a variety of radical topics, including arguments against the existence of God, for free love, and against historical and contemporary state tyranny, as well as overly passive Socialists. It frequently published a list of addresses and personal details of businessmen and others identified as "capitalist spies", strikebreakers, and assorted "enemies of the people". Several books that bear Galleani's name, such as La Fine dell'anarchismo? (The End of Anarchism?) are derived from or are excerpts from essays that appeared first in Cronaca Sovversiva.
