Samizdat

Samizdat was a system in the Soviet-bloc countries wherein people clandestinely printed and distributed government-suppressed literature. Key to the technique was that copies were made a few at a time, and anyone who had a copy and any sort of copying equipment was encouraged to make more copies.

A rough translation would be something along the lines of "Passing on" or "Giving it amongst yourselves". Essentially, the samizdat copy of the text, such as Mikhail Bulgakov's The Master and Margarita[?], were passed from one person to another.

Etymology (Russian):сам (self)+изда(ва)ть (to publish)

Contrast: freedom of press, freedom of speech
