Germany is seeking to have documents and recordings from the groundbreaking mid-1960s trial of leaders of the Auschwitz death camp included in UNESCO's "Memory of the World" register.

The 1963-1965 trial in Frankfurt of 22 men who helped run Auschwitz was the biggest following the Allies' Nuremberg war crimes trials immediately after World War II. It confronted people in then-West Germany with the Nazi past and is credited with being a turning point in German efforts to address the crimes of that period.

The state government in Hesse, where Frankfurt is located, said Thursday that documents on the 454 volumes of files and 103 audio recordings have been submitted to the U.N. cultural agency. It said a decision is expected next year on whether to include them in the register.
