Besides reporting on the activities of the Polish-Czechoslovak Solidarity initiative, the Information Bulletin of Polish-Czechoslovak Solidarity also published information on samizdat periodicals, campaigns for the support of political prisoners, essays on culture and interviews with the proponents of the opposition movement in Czechoslovakia. It was published from December 1987 until January 1990; in total, 16 regular issues (some as double or triple issues) and two special issues were published. The editorial board included activists from Wroclaw (Jarosław Broda, Mirosław Jasiński a Paweł Kocięba), Warsaw (Zbigniew Janas and Wojciech Maziarski) and Prague (Anna Šabatová).
