"The National Atlas (Part II)"

Codex 99 has completed its great series on "The National Atlas," which I originally discussed here. Part II covers the development of an actual National Atlas, the prior versions having been extensions of the US decennial census, efforts that were eventually abandoned. In the 60's beautiful large format paper maps were developed and published in 1970.  The maps of the Atlas can be found online at the US Library of Congress and University of Texas's Perry-Castañeda LibraryMap Collection. The National Atlas, such as it is, can now be found online through the US National Geological Survey, with similar maps available through the US Census Bureau. Codex 99 displays one beautiful NGS map, The North America Tapestry of Time and Terrain, similar to some of the content of the Atlas.
