The book «Albert Soboul's Correspondence with the Soviet Historians» by Varoujean Poghosyan allows us to take a fresh look at the professional and friendly relations between the French and the Soviet historians from the 1950s up to 1980s. The letters to Ya.M. Zaher, A.V. Ado, B.F. Porshnev, A.Z. Manfred, V.P. Volgine, E.A. Kosminsky, V.S. Lublinsky and V.A. Poghosyan himself give us the opportunity to trace the evolution and nuances of Soboul's relationship with his Soviet colleagues. They discuss joint publishing projects, research trips, publications in domestic and foreign press, achievements and drawbacks of their colleagues.
