Tygodnik Mazowsze Solidarnosc – a bulletin of the Polish Solidarity opposition in the period of the Polish People’s Republic, published in 1982–1989.
Underground publications (tissue paper, second circulation) was published in countries where censorship was in force (PRL, USSR, etc.). In Poland publications were published by the opposition such as The Workers’ Defense Committee (KOR) and Solidarity. These were non-debit publications, i.e. without being allowed to be distributed by the appropriate office (in Poland until 1989, it was the Publications and Performances Control Office), often ignoring copyright, and was confidentially distributed. They were published in circulation from a dozen or so copies to several or even tens of thousands of copies by illegal (“underground”) publishing houses or by private persons. The circulations of press and books, for example in the “NOWA”, rarely exceeded 4-5 thousand copies.
Due to militia persecution, espionage infiltration and the system of controlling the trade in paper, ink and printing presses was in force in totalitarian countries. Independent publishing houses never managed to achieve a large coverage, except for the Polish People’s Republic in the second half of the 1980s.
