Consists of correspondence, documents, ledgers, photographs of the Meteor Crater (Ariz.) site, and printed matter of Barringer (Princeton University Class of 1879). The correspondence contains letters which deal with scientific and business activities in mining and meteorology, including those of several companies which Barringer founded or developed, such as the Hanover Bessemer Iron and Copper Company, El Palmarito Leasing Company, the Texas Iron Association, and the Meteor Crater Exploration Mining Company (general manager, George M. Calvocorresses, a major correspondent). The collection reflects Barringer's accomplishment in being the first to advance the theory that Meteor Crater was caused by the fall of a meteoric cluster, probably a small comet. There are a number of photographs, including over 100 cyanotypes and 6 lantern slides, mainly concerned with illustrating various craters and aspects of meteor study, mining equipment, and aerial surveys. There are also letters by fellow college classmate Woodrow Wilson, whose correspondence indicates that Barringer was not only a friend but also a personal adviser on mining and geological matters. In addition, the correspondence includes letters by Theodore Roosevelt, Owen Wister, General Leonard Wood, and Elihu Thomson.

These course materials were removed from the Lecture Notes Collection (AC052), as they are not notes taken by students. Some material in this grouping may never have been in the Lecture Notes Collection but was stored together with material that was. Some are professors' notes for lectures, some are problem sets or laboratory instructions kept by students.
