The Infinity Series establishes a new benchmark for quality and innovation in illustrated reference books for older children. With its inventive, multi-faceted approach to individual subjects, it delivers an absorbing, exhilarating learning experience that will capture the attention of even the most reluctant reader. Each book is packed with additional features - facsimilies and documents tucked into pockets, gatefolds, extended pages with flaps, trace overlays, fold-out maps and a pull-out-poster.
