This book is essentially a listing of 2000 Kanji with two examples of howthey are used in compounds. There is no kanji lookup system, no discussionof radicals, and no order to the list. So if you find a kanji that you do not know, there is no way to look it up in this book. My Kanji Learner's Dictionary is much more useful. I'm confused as to why someone would publish a book like this - it is really not useful at all.
