The Brenthurst Library is a private repository of Africana in Johannesburg built by Harry Oppenheimer in 1984 as he started to disengage from the family's mining interests. It houses a collection of some 20 000 volumes, including rare manuscripts and documents. Among these were the only complete record of the proceedings of the treason trial of Nelson Mandela., until the papers were handed over to the Mandela estate in November 2008.
