Gr 4-7-These three books contain some interesting facts. How many people know that the world's largest building is a Boeing manufacturing plant in Everett, WA, which could house Disneyland within its walls? Thinking Big includes Ford's River Rouge automobile plant with the "world's largest living roof" complete with soil and plants, and the development of the Interstate Highway System. The biggest disappointment in these books is the lack of exciting visuals to enhance the presentations. Given the liveliness of the topics, it is unfortunate that some of the photos are of poor quality and others are merely filler. DK's "Eyewitness" books have raised the bar for quality illustration, pointing out comparisons, intricacies of design, and boxing in text to make facts leap out at readers. These "Learning Channel" titles plod along and don't do justice to their subjects visually.-Edith Ching, St. Albans School, Mt. St. Alban, Washington, DC Copyright 2004 Reed Business Information.
