Query: Great for Arabic, does not cover all black Muslim

I often talk with Black Muslim people in a jail environment. This book gives a better insight into some of their beliefs. There are seven variations of the Arabic Muslim and over five Black Muslims sects. In my library there are several books on the subject and this book is the best so far. Someone should write a more thorough book on the Black sects as they have deviated somewhat from the Arabics.
