The U.S. Geological Survey published the National Atlas of the United States of America in 1971. Since then times have changed, and the technological revolution in cartography today makes it mandatory to take a close look at the concept of a national atlas. This paper focuses on two concepts related to national atlases: the popular conception of a national atlas and the notion that a comprehensive national atlas would contain information on the United States that most commercial atlases would not include. Ideas are presented that describe what a future, comprehensive, digitally produced national atlas for the United States (CD-NAUS) might look like.

Publication in 1976 of the International Stratigraphic Guide climaxed a movement toward unification of nomenclature begun a century earlier when an American committee formed to promote an international meeting of geologists. American stratigraphic practice during the remainder of the 19th Century developed chiefly through the needs of the United States Geological Survey for uniform standards in geologic nomenclature and cartography. The requirement for maps which were usable by the intelligent layman for practical purposes led Directors King and Powell to emphasize the mapping of lithology, rather than time units delineated faunally. This approach was not universally accepted and led to bitter dispute. H. S. Williams and C. D. Walcott deserve credit for clarifying the distinction between terms for time and terms for rocks. Under Director Walcott, the 1890 codification of Powell was modified and formalized into the 1904 "Rules" of the U.S. Geological Survey. A major distinction was the placing in separate sections those rules concerned with lithologic units and those concerned with time and correlation. This dual classification, fundamental to all United States and North American stratigraphic codes during this century, has become a guiding principal in the international efforts at standardization of usage.

An American Language is a political history of the Spanish language in the United States. The nation has always been multilingual and the Spanish language in particular has remained as an important political issue into the present. After the U.S.-Mexican War, the Spanish language became a language of politics as Spanish speakers in the U.S. Southwest used it to build territorial and state governments. In the twentieth century, Spanish became a political language where speakers and those opposed to its use clashed over what Spanish's presence in the United States meant. This book recovers this story by using evidence that includes Spanish language newspapers, letters, state and territorial session laws, and federal archives to profile the struggle and resilience of Spanish speakers who advocated for their language rights as U.S. citizens. Comparing Spanish as a language of politics and as a political language across the Southwest and noncontiguous territories provides an opportunity to measure shifts in allegiance to the nation and exposes differing forms of nationalism. Language concessions and continued use of Spanish is a measure of power. Official language recognition by federal or state officials validates Spanish speakers' claims to US citizenship. The long history of policies relating to language in the United States provides a way to measure how U.S. visions of itself have shifted due to continuous migration from Latin America. Spanish-speaking U.S. citizens are crucial arbiters of Spanish language politics and their successes have broader implications on national policy and our understanding of Americans.
