Gr 5-7 These biographies cover the presidents' lives from birth to death, but the main emphasis is on their political careers. However, the development of the political concepts which prompted their actions is superficial and therefore confusing. Most students will not have enough background information to understand the presidents' motivations. For instance, in Franklin D. Roosevelt there is a very short entry about packing the Supreme Court with no explanation as to how or why the composition of the Court did finally change. Also, Osinski states that under Roosevelt's proposed system for changing the composition of the court there ``could be as many as eighteen judges on the bench.'' Actually, Roosevelt's plan made provision for a maximum of 15 judges. In John Tyler there is an error of judgment: ``It would have surprised Tyler to learn that Hawaii was destined to be one of our fifty states.'' That is a misleading and hypothetical statement. The writing is choppy in all of the books, and they seem to follow a formula as to sentence length and complexity. The illustrations are excellent, plentiful black-and-white reproductions of portraits, newspaper articles, cartoons, woodcuts, etc. They are the best part of these books. Janet E.
