"The agitation library of the German Socialists in Cleveland, a section of the Socialist Party, was rediscovered in 1971 by the German diplomat Peter Schoenwaldt and preserved by him for thirty years. Due to the fact that the books had until their discovery been concealed in a secret room, the original inventory -- with the exception of several volumes of fiction, which were probably not deemed worthy of being hidden -- has survived the years nearly complete and comprises slightly more than 600 volumes dating from 1845 to 1925, among them numerous made-up volumes containing up to 17 pamphlets and brochures." p. 327.
