This book has around 900 colour photographs and about 300 illustrations. It has more that 4000 up to date articles. The book
is compiled by a team of expert authors (of non fiction not stories) and contributors. The book has extensive cross referencing (A cross-reference is when you put sort of a hyper link from one article to another which refers to related information somewhere else, usually to do with the same subject). It has a comprehensive index and a fact packed reference section. The book is ideal for school projects and helped me out with some homework on Anglo Saxons as part of history last year. This book only has information about things from Aboriginal Australians to Arctic Ocean. For things like presidents, fruit or medicine you have to resort to one of the other 16 books.
