I bought this encyclopedia for my 7 year-old daughter who is obsessed with the great cats. She was thrilled! We had borrowed the previous edition (with the tree frog on the front) from the library, so I already knew that she loved the book. But now, with the tiger on the front, it's one of her favorite possessions. We're a month past Christmas, and she is still consulting this book regularly, drawing pictures of the various animals shown in full-color, and learning so many facts that she's becoming a walking encyclopedia herself. The organization and layout is very user-friendly. This is not an alphabetized A-Z book of animals. The mammals, insects, birds, etc. are all groups according to categories of related creatures. This is a very helpful feature. We give the book two thumbs up!!
