Analysis of information sources in references of the Wikipedia article "Kolyma" in English language version.
Secret police authorities in Kolyma today say there are records—sometimes a complete file, sometime just a name on a list—of two million men and women who were shipped to the territory between 1930 and the mid-1950s. But no one knows, even approximately, how many of these prisoners died. Even historians who have spent years studying Kolyma come up with radically different numbers. I asked four such researchers, who between them have written or edited more than half a dozen books on the gulag, what was the total Kolyma death toll. One estimated it at 250,000, another at 300,000, one at 800,000, and one at 'more than 1,000,000.'
