Q: I'm an MT with 20+ years of experience and own most of the Stedman books, which are quite helpful. However, when I cannot find a term in Stedman's, this is the reference I reach for. I cannot tell you how many times this little gem has saved me from lengthy searches for a term. Grab yourself a copy, you won't regret it.
A:
Positive
