I think it's quite hard to keep a book like this current, since much of the information in it is already quite dated; but nonetheless, it's rather impressive. Studios are listed in alphabetical order, each with example images, contact information for each studio, and a short page or so, summarizing their background and most significant works. I will personally be using this book in the future, and intend to keep it on my shelf for quite awhile.
I recommend it for anyone really interested in the animation industry who happens to be looking for a sizable guide to many studios. It's not the most comprehensive out there, but it's visually appealing and useful for research. ( )

The book has texts in English, French and German. The funny thing is: it was written by the directors of the Brazilian animation film festival, but the book wasn't release here by Taschen and it isn't available in Portuguese. The texts about the artists / animators, could have more information and details about more works. However, it's still a good reference book about animators and his works, full of beautiful images and links to their site, when available.
