Query: NO help to me

I have had the WORST luck with this book. As a music teacher, I often use signs to supplement the songs we sing - both in class and in performance. However, out of maybe 35 words I've looked up in this "dictionary", I've found the signs for about five! Words like "special" and "place" are NOT in this book, although they should be.Not recommended.
