This new and exciting series of pocket encyclopedias for young adults is full of instant information and fits in a backpack or back pocket. Featuring a fresh and striking design that is sure to appeal to the middle grade audience, these guides offer a unique catalog-style presentation, which clearly lays out individual species with concise and punchy text covering all of the essential information. These encyclopedias are perfect for back to school, summer reading and every month in between! Each book features four types of spreads: Thematic spreads cover essential information, such as animal anatomy, dinosaur evolution, shark taxonomy, or the characteristics of minerals. Splash spreads cover exciting full-bleed images such as a shark feeding frenzy or a firework display. Catalog spreads build into a comprehensive list of individual species, each with its own photograph, summary key facts, and a short description of unique features. Special boxes and features focus in even more, providing specific details on topics from shark orders to mineral groups and "genius gem" wow facts. Fact files in the reference section contain "top tens" (biggest dinosaurs, fastest animals, etc.) and other reference materials (such as the Moh scale of mineral hardness).
