Book excerpt: The Souls of Black Folk is a classic work of American literature by W. E. B. Du Bois. It is a seminal work in the history of sociology, and a cornerstone of African-American literary history. To develop this groundbreaking work, Du Bois drew from his own experiences as an African-American in the American society. Outside of its notable relevance in African-American history, The Souls of Black Folk also holds an important place in social science as one of the early works in the field of sociology.
