Jhoon Rhee's series of hyung books were the first in the U.S. documenting the ITF forms. Except for this first book, these books present two of the forms for each belt up to 1st degree Black Belt. This book uses the rest of the space to demonstrate the basic techniques.
Overall, excellent presentations of these forms, especially the photo sequences that show you the entire form on one page, which is very useful for quickly scanning the form. Also, the author indicates where the kiai should be, which other kata books I've seen neglect to show you.
