The records of the Wisconsin Correctional Service consist of correspondence, mainly between Ruth Parsons Baker and her father, the Reverend James Parsons, and between Ruth Baker and her uncle, the Reverend Charles Parsons. Although some of the letters are personal, nearly all deal with administrative details of the Society for the Friendless in Wisconsin, including raising money, acquiring and training superintendents and case workers, and logistical considerations, e.g. railroad passes. Because James and later Charles Parsons were national superintendents of the Society, and superintendents of state organizations other than Wisconsin (Kansas-Missouri, California, and Iowa), the papers are of a broader scope than the Wisconsin Division alone.

Included in the collection also is a copy of Fred B. Haynes' The Society for the Friendless, 1900-1952, a thirty-page study of the Society published in 1954.
