January 19 is the day set aside to honor the memory of Dr. Martin Luther King Jr. We celebrate him, in part, because he was one of those rarest of individuals: a courageous man of action who knew that, in the end, the power of his words was his best weapon against injustice. Those words did the near impossible; they spurred others to action--action, it must be remembered, that entailed great personal risk for those who chose to undertake it. Such was the power of his gifts that he gave others courage and resolve they might otherwise have lacked. And his words, nearly 50 years after his assassination, still have the power to change the world. What better way to celebrate Dr. King's life and works than to read those words. Below are several suggestions from Book Hunters.
