The Christian Book Expo has listed award finalists for 2011.  In the “Bible Reference” category, four of the five nominated books have been praised here before.

A Visual Guide to Gospel Events, by James C. Martin, John A. Beck, and David G. Hansen

Crossway ESV Bible Atlas, by John D. Currid and David P. Barrett

The Story of the Bible: The Fascinating History of Its Writing, Translation and Effect on 
Civilization, by Larry Stone [not noted on this blog]

Zondervan Atlas of the Bible, by Carl G. Rasmussen

Zondervan Illustrated Bible Backgrounds Commentary, John H. Walton, General Editor

If judging on the basis of unique value to a Bible student, I would give the award to the five-volume (3,000-page!) commentary set.  The other books are more affordable, and all make 2010 an outstanding year for works in the field.
