Each page presents a number of interesting facts in graphic form. The number and variety of facts is good, as is the variety in the way that they are displayed. Don't expect to become an expert in any area of knowledge using this book, but it does give you many "well I never knew that.." moments.
In all, a good buy, and a good book to have sitting on the coffee table when having guests around, always make an easy start to the conversation; great as a gift too.
