The museum holds an extensive collection of original paper documents from the Khmer Rouge time. These include thousands of forced confessions, film negatives, prisoner and staff biographies, cadre diaries and notebooks, among others.
These materials have been preserved through the work of the museum staff and in collaboration with external experts and institutions, such as Cornell University in 1992, the U.S. National Archives in 1994, and the Documentation Center of Cambodia in 1995. In 2009, after training in Japan, the museum archivists returned with acid-free storage materials to further prolong the life of irreplaceable paper documents.
The archives of Tuol Sleng Genocide Museum are registered as part of the Memory of the World by UNESCO. Most recently, KOICA through UNESCO provided support to digitize all the documents in the archive, along with a searchable database on materials.
