This edition of The Clementine Atlas of the Moon represents a significant enhancement over the first edition. The primary improvement is that we use new mission data for the annotated pages of the atlas. Specifically we use a new global topography product generated using data acquired by LROC, the imaging camera on board NASA's Lunar Reconnaissance Orbiter. For allowing us to use these wonderful data we wish to thank Dr Mark Robinson, the LROC team, and Frank Scholten and colleagues at the DLR Institute of Planetary Research in Berlin, Germany. We'd like to acknowledge the LOLA team whose high-resolution topography of the lunar polar regions was used for LACs 1 and 144.

Also since the initial release of the atlas, the Astrogeology branch of the United States Geological Survey has released a comprehensive set of annotated LACs that use Lunar Orbiter data as their basemap. We thank Jenny Blue and her colleagues for this invaluable resource for lunar scientists and enthusiasts. Finally we thank Danny Caes of Ghent, Belgium, whose meticulous and careful reading of the atlas uncovered several typographical errors in the first edition.
