Trancework by Michael D. Yapko Ph.D. (2003, Hardcover)

I was surprized that this book covers all the do's and don'ts. It was very informational and could be used by practicing therapists. Just be sure that you read everything. Don't skip around because the important information is not highlighted within the text. The author could do more to make important points and definitions stand out in future version. But you can do the same with a highlighter.
