I think the graphic design is a bit over done.  Lots of design an color on the front, but it almost looks messy.  The table of contents is distracting with the busy graphics and colors.  Although, color and graphics are important to pull kids into a book, this is too much.  It almost gives me a headache.

The information is chopped up and spread out in unrelated paragraphs.  For someone who is just browsing, this may be desirable, but ifyou are trying to organize and collect data for a research project.  There are some Book, DVD, and website recommendations in the back.  Along with a small index.  This books would make a nice addition to a library.
