From Christianbook.com:
Keeping all the KJV Scripture seen in the Thompson KJV Bible, this edition has streamlined the traditional Thompson Topics. The Thompson Abridged Reference Bible - King James Version uses only 2000 topics that are key to today's issues. It also contains the notes Dr. Charles Thompson scribbled in the margins of his Bible over a century ago. Many of the helps are moved up into the Scripture. Maps, charts, character studies all become more relevant to the passage you are reading. The slim design makes it the ideal KJV Thompson for carrying!
GreatTracts Bible Review:
We really enjoy using this Bible. The print is small, but dark, and easy to read. Even though there are fewer chains than in a regular Thompson, there are still a ton of references. The Kirvella versions are especially nice. They feel like a high quality calf skin.
