Mines and mineral resources -- Nevada

The records document the first decade of Aurora's existence. The collection contains tax receipts for local businesses and citizens, trader's licenses, abstracts of mine titles, stock documents, and papers of the Independent Order of Odd Fellows, Esmeralda Lodge No. 6. A few records relate to the Kimbal & Canfield company's business in El Dorado County.

The collection consists of promotional material, including form letters, maps, reprints of newspaper articles, and publications, that describe oil and mining investment opportunities in various Western states, including Texas, Colorado, Arizona, Nevada, and New Mexico, during the time period of the Great Depression. The materials were sent to R. E. Blair as a prospective investor in oil and mining ventures.

The collection consists primarily of Clayton's reports on mines and mining districts in California, Colorado, Montana, Nevada, and Utah. There are also a variety of papers, including correspondence, documenting mining in Montana, Nevada, and Utah.

This collection consists chiefly of papers created and collected by Dan De Quille that document a portion of his writing career, circa 1860-1898, as well as a small quantity of material accumulated by his family from 1936 to circa 1956. The papers consist of correspondence, writings, photographs, and ephemera, as well as newspaper clippings collected by De Quille on a variety of subjects.

The major part of the papers consists of reports and maps on the holdings of the Rochester Mines Company in Humboldt County, Nevada (1916-1917). During this period Knopf was on the staff of the U.S. Geological Survey. Also a small amount of professional correspondence and lecture notes, chiefly relating to his career as a professor of geology at Yale University. Eleven of the letters are from Charles Schuchert, a colleague in the department.
