In 1977 one of the Polish censors, , defected to Sweden with stolen classified documents which he published in the ''
. The book was based on one of two copies of guidelines in the safe of every censorship department of GUKPPiW (Główny Urząd Kontroli Prasy, Publikacji i Widowisk''). The official name of the guidelines in Polish was "Książka Zapisów i Zaleceń GUKPPiW" (The Book of Records and Recommendations of GUKPPiW). These materials included photocopies of the originals and personal notes in his notebooks. No-one at his office was allowed to take them out of the building or reprint them: the Bureau censors were allowed only to remove these guidelines from the safe and read them on site. The document was generic in nature: "It's forbidden to write about any info on the disaster in X". "It's forbidden to write about any increase in deaths from xy ". Natural catastrophes, or even carcinogenicity of
asbestos, or noxiousness of the plastic used in artificial Christmas trees were also covered there. Other topics were mentioning the names of censored authors, unless negative arguments about their works were given. Even statistical data about coffee drinking in Poland were banned as this might cause protests against reexporting this product from Poland. In the 1990s when after the Bureau was dissolved and its archives released, not all copies of such censorship guidelines were submitted and their existence was denied. However some years later former censors of the Bureau confirmed that they had such books in their departments, and that they used it as a reference. == See also ==
