So I read this book to find out whether or not it is something I'd recommend to my hearing friends who would like to learn more in-depth information about the Deaf world.
None of the information within was new to me, but I did appreciate that it was laid out in a clear, succinct, Q&A style. I like that people can go straight to whatever chapter/question they are interested in without having to read cover-to-cover. My only complaint is that some of the information is out of date, but to be clear, I read the 2nd edition which was published in the early 1990's. I think the most recent edition is a two-volume 4th edition which probably solves this issue, but I could not affordably get my hands on that one, so this review covers the 2nd edition.
So would I recommend this book to my hearing friends despite being it outdated? Yes. It is a great little repository of information that covers a lot of topics, including more serious ones and awkward ones that my friends may wonder but feel strange asking, and it's all stuff that would be great for hearing friends to know and understand.
Granted, a lot of this information can easily be found online if one knows where to look, but most hearing people don't, so having it all together in a Q&A book not only makes it easier for them to learn this information but it might make them more willing as well. As for the outdated stuff, it would be easy to supplement friends' knowledge on these items if they are earnest enough to read the book in the first place.
I would love to be able to read the updated 4th edition. I know that it includes even more topics than this one, has updated information regarding technology and culture, and is probably much better. But this one is a great start in that one's absence. I will definitely be keeping my copy to loan out to any interested friends.
