Book excerpt: Alexander Bogdanov was a co-founder, with Lenin, of the Bolshevik faction of the Russian Social Democratic Party in 1904. His ideas on the sociology of culture led to the founding of the Proletkult in 1917 and during the 1920s these ideas were taken up, adapted and often distorted in the course of the 'Cultural Revolution'. Bogdanov's textbooks in sociology and economics were widely used during the 1920s. This bibliography of Bogdanov's works takes advantage of the opening of the Party and State archives and provides references to the principal relevant archives in Europe and the United States. Its publication is a landmark in the history of Bolshevism and in the history of Russian social thought.
