Moving more quickly than expected, the 11-nation body overseeing a long-secret archive of Nazi war records set procedures in motion yesterday to open millions of files on concentration camps and their victims before the end of 2007. Officials noted that 10 per cent of all Holocaust survivors now living may be dead within a year. The governing commission of the International Tracing Service, the storehouse in Bad Arolsen, Germany, of an estimated 30 million to 50 million pages documenting the Holocaust, approved recommendations for copying and transferring files to Holocaust institutions for use by survivors, victims’ relatives and scholars. The recommendations must be adopted at a formal meeting of the 11 countries in May.
