I picked this up to encourage my partner to start learning ASL. I find that some of the signs are a bit outdated (the version of missionary that they use, I've never seen, same with nun - this could be down to regional differences too) but more than that this book has a very obvious Christian slant. It is full of Christian terms (Abraham, Adam, Lutheran, Methodist, Salvation, etc) that isn't relevant to most beginners. They don't include terms like Islam or Muslim which is where I really take issue and the bias is obvious. I genuinely wouldn't care if they just made it clear somewhere that this was their intention but it's not advertised at all this way.
I went to the library and picked this up, but after spending some time with it, I think it is a book that I would like to have on my shelf as a reference book.
This edition was used in a Sign Language Course that I was privileged to take in 2006. Learning from a true and invaluable source ( my instructor was hearing-impaired) I was able to glean all that I could in such a fun, quick and condensed setting. This is still a very good reference tool with easily discernible text and illustrations. Recommendation: High
