1,000 Words to Sign by Geoffrey S. Poor.
It is a pictorial dictionary that also includes an instructional DVD showing the signs in motion.
The DVD contains letters, numbers and words that appear in the book both with subtitles (as a learning aid) and without (as a testing aid).
The author includes a touch of linguistic information at the start of the book including a brief history of ASL in addition to grammar. His explanations are clear and helpful.
For those of you interested in learning American Sign Language this book is a great way to kick off your journey and motivate interest. And for those of you who already know some sign, it will serve as a useful resource.
Congratulations Lauren, and my fellow co-worker Darren, for your work on this project.
