These recordings were generated in the preparation and editing of the "Long Walk to Freedom" book and Anthony Sampson's authorised biography. In both of these projects, Ahmed Kathrada worked closely with Sampson and Stengel (who provided professional support for "Long Walk to Freedom") and Mandela. Transcription and digitisation is in process.
One transcribed extract (extract 5) relates to the Rivonia Trial as Mandela tells Kathrada about a conversation he had with a warder at Pretoria Local Prison during the trial about the fate of the accused.
There may be references to the Rivonia Trial in other recordings and in NMPP2009/57 Rick Stengel Interviews with Nelson Mandela.
