Effective use of bold typeface for the keywords, bullet-points and arrow symbols, combined with a small but significant indentation of the decriptive text make this dictionary very easy to the eye.
The top of each page nearest the edge shows not only the first word on that page but also the last. This helps to quickly locate the desired word.
Although I don't usually find the International Phonetic Alphabet easy to use for finding the correct pronunciation of a word (because I can't remember the meaning of the symbols used) this book significantly helps by providing a listing of the symbols and their corresponding sounds at the bottom of each page. Vowels are shown on one pair of facing pages, consonants on the next, repeated throughout the whole dictionary.
Concise usage and origin definitions add to the book's usefulness and browsability.
In summary, an excellent dictionary that will become my default reference book.
