Prehistory book for children

I found a wonderful new book in our collection on prehistory for children. It is "DK Online Prehistory" by Peter Chrisp. The book has its own website that was created by DK and Google.
It gives children a chance to get more information on the articles in the book, by going to the website and typing in the keywords from the book. I was very pleased with the website, it is easy to use and would be a great help to children for study or doing reports. What a great idea to combine books with the web. I have always liked DK books (Dorling Kindersley), they have a great format, kudos to them for a great idea.
