I will not repeat the content of the book (which is very comprehensive) but rather on the value. The Amazon price is very reasonable for the exceptional quality of the book. Everything is cared for in every detail and the material of the cover is pages are perfect. I'll add that you will find complete information about Tolkien's world (geography, history, sociology, character etc ...). I liked the presentation, organization specifically encyclopedia and of course the many same picture if some are oddly made. In short it is a wonderful gift for anyone interested in the Lord of the Rings or the works of Tolkien.
