This volume is the Tenth Anniversary Edition of a book that was honored in 1992 as an "Outstanding Book" by the Gustavus Myers Center for the Study of Human Rights in the United States. Reprinted many times since its first publication in 1991, Who Is Black? has become a staple in college classrooms throughout the United States, helping students understand this nation’s history of miscegenation and the role that the "one-drop rule" has played in it. In this special anniversary edition, the author brings the story up to date in an epilogue. There he highlights some revealing responses to Who Is Black? and examines recent challenges to the one-drop rule, including the multiracial identity movement and a significant change in the census classification of racial and ethnic groups.
