PLB $51.70; ebook $51.70. Gr 9 Up In a clumsy grab for reader interest, these compilations of material from Britannica Online Encyclopedia offer lengthy, academic introductions to selected large predator and prey animalsmeaning no insects, arachnids, or microbial creaturesaccompanied by occasional charts, tables, and a sparse assortment of cramped, staid color photos. Discussion of "Prey" is largely relegated to the Grazers title (which treats only land animals ranging from deer to marsupials), and crocodiles are arbitrarily included in Meat Eaters rather than in Reptiles and Amphibians . Each volume closes with bibliographical essays. The books' drab format, as well as the fact that their contents are readily available online, will limit demand for this series.
