Very interesting book.

Pros: This book will give you a glimpse of Sign Language that you have never seen before. Not only does it go into the mechanics of Sign, it also explores history and culture of Sign. This book is more about history/sociology than it is linguistics but I would still recommend it to anyone who is interested in linguistics. Also, be aware that the book is a little dated.

Cons: This book is a bit dry. The footnotes feel like sludge to fight through. The author uses technical vocabulary and the sentence structure feels clinical/academic. This is one of those rare books where I disliked the reading experience but really enjoyed the content itself.
