Samizdat
http://en.wikipedia.org/wiki/Samizdat
Samizdat was the clandestine copying and distribution of government-suppressed literature or other media in Soviet-bloc countries. Copies were made a few at a time, and those who received a copy would be expected to make more copies. This was often done by handwriting or typing.
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.
Vladimir Bukovsky defined it as follows: “I myself create it, edit it, censor it, publish it, distribute it, and [may] get imprisoned for it.”
