The letters, documents and photographs were kept by the South African historian Tim Couzens. They were given to him by Dan Twala with the view to publishing the letters between himself and his wife. In 2020, the late Tim Couzen's wife Diana Wall, together with Joel Cabrita, a historian of modern Southern Africa at the Stanford University, who worked with the papers, suggested to deposit the Regina Twala papers at the University of the Witwatersrand, which subsequently happened in 2021.
