The largest audiovisual collection of its kind in the world, the Holocaust Collection is composed of over 54,000 WWII era testimonies of Jewish survivors, political prisoners, Sinti and Roma survivors, Jehovah's Witness survivors, survivors of eugenics policies, and gay male survivors, as well as rescuers and aid providers, liberators, and participants in war crimes trials.

In 1975, a communist regime known as the Khmer Rouge conquered the Cambodian capital of Phnom Penh. The occupation set in motion a four-year campaign of genocide that would wipe out 2 million people – a quarter of the country’s population. Developed through a partnership between USC Shoah Foundation and the Documentation Center of Cambodia, the Cambodian Genocide Collection offers testimonies of survivors who escaped the killings from 1975 to 1979.
