Armed with footnotes and provisioned with a healthy bibliography, Italian Anarchism, 1864-1892 is not an easy read for the casual reader, or even the casual “antiauthorian leftist.” Isn’t that the euphemism for anarchist these days? Still, I don’t regret the time I spent reading—insurrection after insurrection, congress upon congress—the nearly 300 pages of text in Nunzio Pernicone’s history of these three decades.
