I was looking for a good encyclopedia for my son of 10 years _who love books at any genre_ that combines beautiful illustrations and clear exploration, original and even entertaining the world and the areas of scientific, geographic, history, etc. lartistique Disappointment by receiving this book, bought blindly, inspired by the many good reviews, we discover there from opening a formal dull page in execrable image quality _and unfortunately often cut by a few available judicious drawings in full binding (not the top one for between many cards therein), only a few dozen old photos on 313 pages that make up the encyclopedia. Besides blurred drawn illustrations and outputs a book of 8O years, explanations prove worthy of a textbook _autrement rébarbatives_ said. For my son, stay on a page is so difficult topics are treated in an "adult" (lack of anecdotes, a fun and modern twist in the narrative stories to brighten and give the desire for children) and a little vocabulary suitable for young elementary school readers, but for teenagers, already in college. Dialectic is not considered more ... In short if you want a "good" book, modern, interesting, arousing curiosity and the desire to teach children, put a few euros more in another edition of encyclopedia
