Soviet newsstands do not sell foreign anti-Communist papers, and it is not even possible to buy every issue of the Communist periodicals. Even informative periodicals such as America are in very short supply. They are on sale only in a very small number of kiosks, and are immediately snapped up by eager buyers, generally with a "makeweight" of non-saleable printed matter.

Any person wishing to emigrate from the Soviet Union must have a formal invitation from a close relative. For many people this is an insoluble problem, e.g. for 300,000 Germans who wish to travel to the German Federal Republic (the emigration quota for Germans is 5,000 a year, which means that one's plans would have to cover a sixty-year period!). This is an enormous tragedy. The position of persons who wish to be reunited with relatives in non-Socialist countries is particularly tragic. They have no one to plead their case, and on such occasions the arbitrary behavior of the authorities knows no bounds.

Freedom to travel, freedom to choose where one wishes to work and live, these are still violated in the case of millions of kolkhoz workers, and in the case of hundreds of thousands of Crimean Tartars, who thirty years ago were cruelly and brutally deported from the Crimea and who to this day have been denied the right to return to the land of their fathers.
