Taking a tour of the MLK Collection at Sotheby's [audio 7min]

Ed Gordon takes a tour of the personal papers and books of the Rev. Martin Luther King, Jr., on display at Sotheby's auction house. The collection, valued at about $30 million, was meant to be auctioned this week. Instead, private donors purchased the collection and will donate it to Morehouse College in Atlanta, the civil rights icon's alma mater.
