*Excerpt: K. Marx, *Capital* (vol. 2), ch. 6: 'The Costs of Circulation'; I.: 'Genuine Costs of Circulation'; (b): 'Book-keeping' [marxists.org, Oct. 2021]*
---copied out by MOC. " Book-keeping, as the control and ideal synthesis of the process, becomes the more necessary the more the process assumes a social scale and loses its purely individual character. It is therefore more necessary in capitalist production than in the scattered production of handicraft and peasant economy, more necessary in collective production than in capitalist production. But the costs of book-keeping drop as production becomes concentrated and book-keeping becomes social."
