"'The problem of the twentieth-century is the problem of the color-line.' Originally published in 1903, The Souls of Black Folk is a classic study of race, culture, and education at the turn of the twentieth century."
This book was a recommendation by a friend who read it for her studies. A very thorough and interesting study of black culture in the United States, the achievements and problems of the African American society. Highly recommendable even if you are only remotely interested in this kind of subject.
