Book excerpt: "For the Soviet bloc, the struggle against foreign radio was one of the principal fronts in the Cold War. Poland's War on Radio Free Europe, 1950-1989 tells how Poland conducted this fight, a key part of the wider effort "to control the flow of information and ideas, which largely determined the Communist regimes' ability to command their societies and to meet their political and ideological goals, " according to Paweł Machcewicz. This is the first book in English to use the unique documents of Communist foreign intelligence operations so widely, and it also employs propaganda materials and personal interviews with Radio Free Europe people and with party and security functionaries. The English translation reflects further discoveries of documentation since the original publication in Polish in 2007." -- Publisher's description.
