The description from the book jacket is rather accurate and I'll quote it here:
-- Start quote --
In The Lord of the Rings Sketchbook Alan Lee reveals in pictures and in words how he created the beautiful watercolour paintings for the special centenary edition of The Lord of the Rings. These images would prove so powerful and evocative that they would eventually define the look of Peter Jackson's movie trilogy and would earn him a coveted Academy Award.
The book is filled with over 150 of his sketches and early conceptual pieces to show how the project progressed from idea to finished art. It also contains a selection of colour paintings reproduced in full-page glory, together with numerous examples of previously unseen conceptual art produced for the films and many new works drawn specially for this book.
The Lord of the Rings Sketchbook provides a fascinating insight into the imagination of the ma who painted Tolkien's vision, firstly onto the page and then in three dimensions on the cinema screen. It will also be of interest to many of the 100,000 people who have bought the illustrated The Lord of the Rings as well as for budding artists interested in unlocking the secrets of book illustration.

Full coloured paintings are few actually. But this book has an amazing collection of pencil sketches. The chapters are sorted by places that appear in the book, in chronological order.
With the author's comments, it makes this book sort of a "Making of" book together with it being an "Art of" book. So that's really a plus.
It should interest concept and fantasy artists. Oh, and also Lord of the Rings fans.
