WASHINGTON (AP) — From Adolf Hitler down to the petty bureaucrats who staffed the Nazi death camps, thousands of perpetrators of World War II war crimes were eventually written up in vast reams of investigative files — files that now, for the first time, can be viewed in their entirety by the public.

The U.S. Holocaust Memorial Museum in Washington has obtained a full copy of the U.N. War Crimes Commission archive that has largely been locked away for the past 70 years under restricted access at the United Nations. On Thursday, the museum announced it has made the entire digital archive freely available to visitors in its research room.
