In 1989, the Soviets released much of the German documentation, death certificates, roll-calls, cremation lists, etc, that they had found at Auschwitz, in January 1945.
The Germans had left this documentation when they evacuated.
The Soviets, came across it and conveniently "lost it" in their archives for some 45 years.
In 1989, Mikhail Gorbachev presented it to the Red Cross which then "lost it" in archives in Arolsen, Germany.
The death certificates themselves, were official German documents, issued by Auschwitz camp doctors, upon the death of an inmate. Each death certificate includes the deceased person's full name, profession and religion, date and place of birth, pre-Auschwitz residence, parents' names, time of death, cause of death and a camp physician's signature.
The death certificates are mainly from the years, 1942 and 1943.
The death certificates record the names of 68,864 individuals, who died at Auschwitz (Birkenau), of whom about 30,000 were listed as Jews.
