Google today announced the grand opening of the Nelson Mandela Digital Archive, an online collection of digitized photos, videos and documents centering around the former South African president. The site, based out of the Nelson Mandela Centre of Memory in Johannesburg, South Africa, was developed with the help of $1.25 million in funding provided by the software giant. The collection includes unseen drafts of Mandela's work, letters to friends and family members and diary entries made during his 27 year imprisonment. The multimedia archive is available for view now. You can check it out by clicking the source link below.
