A new film called “All Eyez On Me” celebrates the life of rapper Tupac Shakur on what would’ve been his 46th birthday. The Atlanta University Center Robert W. Woodruff Library is home to a huge collection of Tupac’s works, including handwritten manuscripts, writings from his diary, song lyrics, and other personal items. We talk with hip-hop scholar Nsenga Burton about the collection and Tupac’s legacy.
