James Baldwin was a uniquely prophetic voice in American letters. His brilliant and provocative essays made him the literary voice of the Civil Rights Era, and they continue to speak with powerful urgency to us today, whether in the swirling debate over the Black Lives Matter movement or in the words of Raoul Peck’s documentary “I Am Not Your Negro.” Edited by Nobel laureate Toni Morrison, the Library of America’s Collected Essays is the most comprehensive gathering of Baldwin’s nonfiction ever published.
