In seventeenth-century France, Colbert built a more effective state administration not by rationalizing state offices but by using public documents to increase the government's intellectual capacity to exercise logistical power and engage in territorial governance. This pattern calls into question Weber's model of the genesis of "modern officialdom," suggesting that its source was not social rationalization, but rather the identification and management of expertise. Colbert recruited into government nascent technocrats with knowledge useful to territorial politics, using contracts and other documents to limit their independence and subordinate them to patrimonial authorities. They exercised specific duties and impersonal powers in jurisdictional areas-much like modern technocrats. Their expertise enhanced the intellectual capacity of the administration to exercise territorial power and made the state less dependent on patrimonial clienteles without challenging the patrimonial culture of power/knowledge. Keywords Weber . Bureaucratic files . Power/knowledge . Political networks . Distributed cognition . Public documents . Roman numerals We know from Weber et al. (1978) the importance of bureaucratic files to modern forms of administration, but we know relatively little historically about how public documents were developed, written, circulated, and used for political effect, or about the types of regimes they supported. We also know from Foucault (1966Foucault ( , 1977aFoucault and Gordon 1980) the importance of the circulation of knowledges to practices of power, but we are only beginning to understand how the design of files and movement of information contributed to modern governments. Becker and Clark (2001) have made a case for studying these "little tools of knowledge;" Porter (1995) has demonstrated the importance of numbers in bureaucratic paperwork; and Patrick Theor Soc (2011) 40:223-245
