The present work proposes to investigate how the disputes between the Brazilian State and the authors of textbooks took place, between 1995 and 2016, around the constitution of a concept of textbook, understood here as a know-how. In this sense, I list the documents produced and disseminated by the Brazilian Association of Authors of Educational Books (ABRALE), and the PNLD Guides, prepared by the Brazilian State. Such productions were observed in the light of Content Analysis, which made it possible to expand their reading to reach practical, psychological, historical, economic and sociological aspects (Laurence Bardin, 1980), which were consolidated from the writings of Jürgen Habermas (1996) and Michel de Certeau (2013), authorizing the observation of language and practices in the world as two sides of the same coin, elements that would dialectically compose the ways of acting, producing and relating to reality.
