There are two publications for the movie Avatar that delve more into the world that James Cameron put together. This is the east informative of the two, however it is also the better one if you are interested in better sized images and illustration. Avatar: The Movie Scrapbook is written for the young adult reader, and provides a pretty good amount of information on the world of Avatar. Even better is, unlike the other Avatar book, this one is full sized and with lots of great photos and illustrations that you can look at with ease.
While it doesn't give you all the information there is to the vast world of Pandora, or the advanced technology of the Earth forces it does deliver a fair amount of both. This includes some things not actually seen in the movie, but are officially part oft that universe.
Enjoyable read for those who loved the movie and want more details on a variety of things depicted in the movie. The books is written like a travel guide/visual dictionary, and even though the title is called "Movie Scrapbook", there is nothing written about the film making process at all.
