Merriam Webster Children's Dictionary
In evaluating a children's dictionary, there are two test words we  always check first: "e-mail" and "iguana." After all, if "e-mail" doesn't appear  in a dictionary, how up-to-date can it be? And iguanas, well, what kid doesn't  want to read all about this "very large tropical American lizard with a ridge of  tall scales along its back"? We are happy to report that this fine dictionary is  above and beyond our gold standard. Not only are there definitions for each of  the test words, there are illustrations for each, as well! This 912-page  illustrated dictionary is packed with great information, including world maps on  the inside covers, an easy-to-use how-to guide, and a reference section with  facts and maps of the continents, pictures of flags from countries around the  world, U.S. presidents and vice presidents, pronunciation guides, signs and  symbols, and lots more. Sandwiched between this wealth of facts and figures are  846 pages of definitions with DK's trademark crisp, clear photographs  illustrating many of the words. One of the handiest features in this volume is  the multicolored alphabet running down the outer edges of every single page,  with the featured letter highlighted for easy reference when flipping through.  So get out there and e-mail all your iguana friends about this terrific  reference guide! (Ages 9 to 12)--Emilie Coulter--This text refers to an out of print or unavailable edition of this title.
