Three volumes of miscellaneous Draper correspondence, 1838-1891, mainly incoming letters concerning his many Kentucky research interests. The letters are arranged chronologically: 32 CC, 1838-1876; 33 CC, 1877-1887, February; 34 CC, 1887, March-1891. A few--less than half a dozen-early letters were addressed to persons other than Draper. His correspondents included officers and staff of the Kentucky Historical Society, the Filson Club, Kentucky University, and the Public Library of Kentucky in Louisville; and other historians, editors, congressmen, and descendants of Virginia and Kentucky families. Bowman, Campbell, Hart, Lewis, McDowell, Russell, and Shelby are surnames scattered frequently throughout the volumes. Others discussed in one or more letters of more specific years include: James Gray (1883), Willoughby Griffith's family (1873, 1887-1888), Gabriel Jones (1885), the Kincaid family (1884), John Hancock Lee (1886), the Renick family (1890-1891), James and Joseph Simrall (1868), and Aquilla Whitaker (1891).

In 1858 John D. Shane advised Draper on the duty of the historian to write as well as to collect and a few months later (1859) offered a copy of a Simon Kenton portrait. Samuel Agnew's letter in 1869 sheds light on Draper's acquisition and disposition of Shane's papers. Numerous letters in the 1880s came from readers and recipients of King's Mountain and Its Heroes, a volume which stimulated many to make genealogical inquiries to Draper. A long poem entitled “Night Scene at Drennon Springs, Kentucky” was sent (February, 1887) by its author, Reuben T. Durrett. Beginning in 1865 and continuing through the next two decades, writers commented on the Civil War and its leaders such as Abraham Lincoln and Jefferson Davis, on Reconstruction, and on Democratic politics. A printed circular titled “The Centenary of Kentucky” announced plans by the Filson Club for a centennial exhibition and celebration on June 1, 1892.
