Correspondence and Notes (10 folders), 1830-1865

The research materials file is comprised of three types of files.  The first consists of a collection of Horace Mann's correspondence transcribed by Louise Hall Tharp and her notes on this material.  There is also a collection of similar correspondence which Tharp did not use in her book.  The Mann correspondence is organized chronologically.  Also included in this series are Tharp's research notes organized by chapter.  Material does not appear for all the chapters.  Finally, the research materials file contains Tharp's own letters of inquiry and related responses from research and government agencies, public offices, archives and repositories.  These letters are grouped by subject heading as originally designated by the author.  A separate folder contains a number of newspaper and magazine clippings collected by Tharp on Mann.
