Which is the most accurate Martin Luther King, Jr. biography?

"The Autobiography of Martin Luther King, Jr.," is the most accurate biography of the civil rights activist because it is the literary work closest to a first-person account by MLK himself. The book is a collection of his unpublished writings, interviews, recordings and correspondence, edited by Clayborne Carson.

In addition, "Martin's Big Words: The Life of Dr. Martin Luther King, Jr." is a highly-rated picture book for children who wish to know more about the Nobel Peace Prize winner's life and works. Martin Luther King, Jr. was assassinated on April 4, 1968, on the balcony of a Memphis, Tennessee motel room, before he had the chance to write his autobiography.
