An Introduction to the Bible
Pick up any book. You see its title. It may be American History, or The Vegetation of Hawaii, or How to Fix Plumbing. The title tells you the subject matter, and usually the next thing you want to know is the name of the author. A book on England written by Adolph Hitler would probably not be so good as one written by Winston Churchill. Nor would I trust Stalin even though he had written The History of Russia.
