Informative details about each landmark’s history and construction are the best part of this set. Books have a single-chapter format with one to three declarative sentences on one side and a full-page photo or illustration on the other. Each has a solid locator map, a description of what the landmark commemorates and its contemporary use, information about its inspiration and construction, and a brief visitor’s guide. A concluding page provides thumbnail photos with additional facts. Advanced terms are defined in a photo glossary that has a higher reading level than the text. Photos are bright and colorful. . . . A solid additional choice.
