The largest and most comprehensive book of sign language ever published.

It's a dictionary, so there's not much that can be said about it as a review.
The layout is acceptable and considering I'm most likely using it to verify my own knowledge, I can't really call it out on any errors.

This dictionary is an invaluable tool. There are lots of words included, each accompanied by an illustration and detailed instructions on how to sign it correctly. There are some words that I felt should have been included because they're so common (certain colors, for example), but other than that, this is an awesome resource.

This dictionary has a lot of weirder signs which is fun. The illustrations have descriptions as well so you can get the correct sign. I do get annoyed when I forget something basic like a color though, because they are not in this dictionary. I have to look it up in my textbook instead.
