This entry in an ongoing series (Ann-Jeanette Campbell's The New York Public Library Amazing Space, p. 551, etc.) offers a history of African Americans in a question and answer format, from the earliest slaves to the present day, illustrated with black-and-white photographs and archival drawings. Included is information about politics, the arts, protest movements, and publications. Boxes give quick biographies of major figures and interesting details on such diverse subjects as black cowboys, race riots, and the origin of the term ``Jim Crow.'' Comprehensive enough for classroom use, the book is dry reading for one sitting, but the wide range of material and the recommended reading list is provocative enough to launch research in several directions. (index, not seen, glossary, bibliography, index) (Nonfiction. 10-13)
