The study analyses the censorship legislation and censorship records from the period of the Great French Revolution with the aim of pointing to the existence of a latent world in the history of communications as a result of the action of disciplining pressure. It captures the investigation of the distribution of anonymous political pamphlets and the unsuccessful search of the whole of Hungary for the secret private printing press with the aim of eliminating the problematic anonymous texts that threatened the public peace. Analysis of the innovative censorship legislation and sources on the investigation and testimony of importers enable us to generalize about not only the adaptation of importing practices to the adjusted conditions, but also about the methods of exculpation in the detention of suspected goods. The study shows that the illegal book trade was an important part of the history of communications, which spread and reproduced untolerated ideas in spite of prohibitions.
