The Correspondence series forms the heart of the collection. The bulk of the correspondence (Subseries 2A and 2D) is between Frances Hodgson Burnett (FHB) and her younger son, Vivian Burnett (VB), and spans the the late 1880s through her death in 1924. There are also letters between FHB and her older son, Lionel Burnett, prior to his death in 1890, as well as between FHB and her beloved sister, Edith Hodgson Fahnestock Jordan. Topics range from her busy social life and writing and play producing career that was divided between America and England, as well as descriptions of her many trips through Europe and other places around the globe. The eight subseries are divided among sender (FHB, VB, family and friends/other) and recipient (FHB, VB, family and friends/other, Constance Buel Burnett). Many letters include their original envelopes and therefore the respective postmark stamps, where legible, are used to date many of the letters by month, day and/or year. Some of the undated letters have a year penciled on them by hand and, on occasion, excerpts from letters enclosed within penciled brackets that appear to match some of the excerpts published in Vivian Burnett's 1927 book about his mother titled The Romantick Lady. Not all the penciled years may be accurate, however, and some have question marks and have subsequently been filed with the undated letters. An extensive number of letter excerpts published in Gretchen Holbrook Gerzina's 2004 biography, Frances Hodgson Burnett: The Unexpected Life of the Author of The Secret Garden, are labeled "Penny Deupree private collection" in the Notes section at the end of the book (Gerzina was granted access to Vivian Burnett's collection of FHB materials that was inherited by Penny Deupree, VB's granddaughter) and have been used to cross-reference some of the letter dates in this collection. There are also several penciled notes on slips of paper that summarize certain letters' contents and they have been retained with the original letters. Preservation photocopies were made for some of the letters in Subseries 2D (Vivian Burnett to FHB) and they are included with the originals.

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.
