ENThe purpose of the article is to show how the use of information skills created conditions for the career of their holder. The attempt was made to identify the regularities and trends in the social mobility of scribes; the ways and tools of scribes’ entry into the profession; the direction of their career development; the peculiarities of scribes’ vertical careers; the degree of their advancement in the offi cial hierarchy; to characterize these careers. The obtained results showed that the career opportunities of clerks were progressing. The position of a clerk was not popular with the aristocracy, but it opened up opportunities for individuals of the lower groups of the nobility. Candidates for the post of clerk could be endowed with intrinsic motivations for taking up the post, connected with their high intellectual and cultural requirements. The growth of the clerk’s official and professional status did not change the clerk’s place in the official hierarchy, but created conditions for a vertical career for those who held this position. This career opened access to high positions. Two main shifting types of clerical careers emerged: the “bureaucrat-intellectual” and the “statesman”. The latter was so focused on the vertical career prospects open to him that, unlike his predecessor, it was not distracted by active cultural and intellectual searches.
