Petr Chaadaev. Philosophical Letters Addressed to a Lady
P. Chaadayev, a Russian philosopher (1794–1856), wrote 8 'Philosophical Letters' about Russia, which circulated in Russia as manuscript for many years. The works could not be published in Russia because of its highly critical nature of Russia's significance in world history and politics.

[La Russie en 1839] by Astolphe Marquis de Custine (Russian translation)
The Marquis de Custine's record of his trip to Russia in 1839 was widely read in England, France, and Germany but banned in Russia. Nevertheless, some books printed in France were smuggled in and made an impact on Russian society. Poorly-abridged versions of the book were published in 1910 and in 1930 in the Soviet Union. Finally, an unabridged version was published in 1996.
