Samizdat was a key form of dissident activity across the Soviet bloc in which individuals reproduced censored publications by hand and passed the documents from reader to reader. This grassroots practice to evade officially-imposed censorship was fraught with danger as harsh punishments were meted out to people caught possessing or copying censored materials.
The techniques to reproduce the forbidden literature and periodicals varied from making several copies of the content using carbon paper, either by hand or on a typewriter, to printing on mainframe printers during night shifts, to printing the books on semi-professional printing presses in larger quantities. Before glasnost, the practice was dangerous, because copy machines, printing presses and even typewriters in offices were under control of the First Departments (KGB outposts): reference printouts for all of them were stored for identification purposes.
