The imposition of martial law in December 1981 was a major setback for independent publishing. But, despite the confiscation of printing equipment and the arrest of opposition leaders, the clandestine press quickly resumed issuing bulletins. By the end of 1982, some forty publishing houses were producing a great variety of books, brochures, and serials. Not only did the Jaruzelski regime fail to infiltrate and shut down such publishing operations, it allowed considerable freedom of expression in the "legitimate" press. For example, the influential Catholic periodical, Tygodnik Powszechny (Universal Weekly), founded in 1945, provided an independent voice defending the rights of the Polish citizenry.

After the formal suspension of martial law in July 1983, the regime grew increasingly tolerant toward independent publishing. The underground press diversified to reflect the widening spectrum of opposition points of view. By 1986 only about half of the known independent serial titles were organs of Solidarity.

As the independent press grew more diverse, the state press increasingly cited articles published in underground periodicals and even began to publish "illegal" books. In 1986 the regime granted legal status to Res Publica, a scholarly underground journal representing a moderate social and political philosophy. Meanwhile, the Catholic press grew ever more prominent when dozens of church publications were resurrected after long being banned.

The Jaruzelski regime's increasingly liberal attitude toward the print media was motivated not only by a desire to achieve national reconciliation, but also by the realization that the state could not suppress three highly prolific publishing networks--the underground press, the church-sponsored press, and the émigré press in the West. After the mid-1980s, the nonstate publishing houses averaged 500 to 600 new titles annually.
