The Cambridge Concord Edition has been a favorite presentation of the KJV for over half a century. The Bible text is supported by a variety of study aids: a concordance, a dictionary, a glossary, and 15 color maps. There is also a family record section and a presentation page. The new Bibles are bound in black calf-split leather, a fresh binding style for this edition. Calf-split leather is a superior grade to French Morocco leather, tanned to approach the quality and feel of full-grain calfskin. Both Bibles have two ribbon markers, and one comes with a thumb index, a rare feature in Bible publishing.
