The Harlow Lindley Collection, although relatively small, is rich in material related to Quaker history and the history of Wayne County, Indiana, especially its educational history.The collection consists of historical materials collected by Lindley and of Lindley’s correspondence with such prominent nineteenth- and twentieth-century Friends as Charles F. Coffin, Joel Bean, Allen Jay, Timothy Nicholson, and Barnabas C. Hobbs. The materials in the collection reflect Lindley’s interest in United States, local, and Quaker history and in genealogy. Many of the letters are responses to requests for documents or reminiscences of Quakers about early Quaker settlements and communities or the involvement of Friends in reform movements such as abolitionism.  Lindley directed observances of the centennial of Indiana Yearly Meeting in 1921 and of Earlham’s 75th birthday celebration in 1922, and files of materials reflect these events.  In the 1930s and 1940s, he also worked extensively with Thomas W. Marshall and William Wade Hinshaw to gather Ohio Quaker records for volumes IV and V of Hinshaw’s Encyclopedia of  American  Quaker Genealogy;  Lindley also acquired papers and manuscripts of other historians.  These include a manuscript history of education in Wayne County prepared by one J. M. MacPherson in the 1880s; papers of Isaac Jenkinson, a Richmond attorney and editor relating to his research on Aaron Burr, and a number of histories of monthly meetings of Friends in Ohio and Indiana.  A few photographs are also included in the collection.  Of special interest is a carte-de-viste of Nathaniel Newlin (1768-1867) of Parke County, Lindley’s great-grandfather and one of the first Quaker settlers in western Indiana.
