Sorry, but this resource simply kicks ass, keeps kicking ass and won't stop kicking ass. There are about 1200 glyphs, glyph compounds and Mayan syllablic symbols in this book, clearly laid out and easy to find. Better yet, there are several indexes in the back of the book that allow you to look up the concept you want in Mayan, in Spanish and in English, as well as by subject matter and by T-Number (for those who know what that is), so you can slice the information any way you want/need it.
There are older glyph dictionaries on the market, all superceded by this powerful work. My only complaint is a minor one and is aesthetic; I thought the glyph drawings were a little crude, and I wanted them to be neater, cleaner, clearer and in short more elegant. Maybe in the next edition. If you want the fun of translating an inscription on a vase or a lintel or a stela, this work will get you going and even allow you to complete a translation. I used it for an illustrated book I was writing, which had pictures with captions in ancient Mayan, and I referenced this work to create the captions. Even if you don't plan to translate a thing and just want to see what those crazy Maya were up to 1000 years ago with the only complete written language in the New World, this is your book.
