I bought this book a couple of years ago and I've been using it ever since. I am buying copies for my colleagues now because of Christianbooks' fantastic sale and because I believe every Bible student and especially teachers should have it in their library.
Our small group is using this as a study to learn more about each book of the Bible and their groupings. You study the verses but seldom do you study who wrote the book, when and why. Quite eye opening even for the most veteran Bible learner.
