The Usborne Internet-Linked Encyclopedia Of World History
We've read through quite a bit of this so far. We skipped the caveman stuff since I don't necessarily subscribe to the evolution/caveman theory. We did enjoy the ancient world part and the middle ages.
We use this as a history spine. We read a page or two to get a general feel about what happened and the major people of that time period. Then we add other "living" books to gain depth.
I like how this book is organized. It is color coded by continent which makes it easy to flip through to understand the flow of history in a certain place. The pictures are well done, colorful and full of detail. Not too bloody and most persons either have clothes or have certain parts turned away/blocked by something.
My kids spend hours looking through this book. We use this constantly and I'm very happy with the quality of the book and the information included. I would highly recommend the hardcover version though.
