THE INTERNATIONAL SOCIETY OF GULAG RESEARCHERS (ISGR) was founded in 2009 after lengthy preparatory work, upon initiation by Hungarian- American historians. We can find renowned Hungarian, American, Canadian, Ukrainian and Romanian professors, researchers, survivors and their descendants among its members. The goal of the ISGR is to research and present to the public the story of the persons - primarily innocent civilians - who were deported as political prisoners, POWs, or internees by the Soviet armed forces to the various prisons, forced labour camps and forced labour settlements of the GULAG and the GUPVI. This yearbook is also a part of accomplishing this goal. On 20 January 2015, the Government of Hungary announced - in Government Resolution No 1009/2015, upon the initiative of ISGR, among other organizations - the "MEMORIAL YEAR OF THE POLITICAL PRISONERS AND FORCED LABOURERS DEPORTED TO THE SOVIET UNION". The Memorial Year was extended until 25 February 2017. The ISGR created this extremely interesting book, filled with new information and innovative approaches, in connection with these three extended Gulag, Gupvi Memorial Years. The 17 authors, renowned historians and researchers of this topic, together with young PhD students from Hungary, Romania, and the Ukraine, give us insight into the operations of the Gulag and the Gupvi, two terrible terror systems, stretching far beyond the borders of the Soviet Union, and highlight the number and the fate of the people who fell victims to these horrible systems.
