This is an excellent elementary level nonfiction series. "Who Was Elvis Presley?" is the second book I've read from this series (the first was Dr Suess) and I can't wait to share it with my students. The text is simple and straightforward and it doesn't gloss over the uglier facts of Elvis's life, such as his drug addiction and nasty temper; many biographies for children read more like hagiograpies, skipping the unpleasant truths about their subjects, but the Who Was...? series doesn't shy away from reality and the subjects of the biographies come across as real people, not just idols. My only criticsm is the illustrations; they aren't bad, but I think it would be stronger with actual photographs of Elvis and Graceland.
