ドイツ・イデオロギー
According to historian Colum Leckey, David Riazanov's chief achievement lay in the realm of Marxology — acquiring, preparing, and publishing for the first time previously unknown writings of Karl Marx and Frederick Engels. Included among these were the works "The German Ideology," sections of "The Economic and Philosophical Manuscripts of 1844," "The Critique of Hegel's Philosophy of Right"' and "Dialectics of Nature."
