Series consists of five sub-series. The first four reflect original order given to them by their creator; the last sub-series was created out of correspondence scattered loosely throughout the papers. The five subseries are as follows:
With Family Members, n.d., 1876-1964, Volumes 8-9.
This sub-series extends beyond Seton's date of death because of correspondence concerning him by surviving members of his family, addressing themselves to either his widow Julia Moss Seton, or to his adopted daughter, Dee Seton-Barber.
With Individuals and Organizations, n.d., 1881-1961, Volume 9.
Alphabetically arranged, this sub-series may reflect Seton's dealings with people whom he held in high esteem.
With Publishers, n.d., 1895-1965, Volumes 10-11.
This sub-series consist of contracts and royalty records. There is also information on the preparation of a number of Seton's manuscripts for publication.
Chronological, n.d., 1890-1946, Volumes 11-15.
This extensive sub-series holds information on all aspects of Seton's activity.
Chronological (Created), n.d., 1883-1947, Volumes 16-17.
This sub-series was complied from correspondence found loosely scattered throughout the papers, and also holds documentation dealing with all aspects of Seton's activity.
It should be noted that researchers interested in some particular subject should review all correspondence sub-series. For example, the sub-series, "With Publishers", is not integrally exhaustive; there is information on Seton's dealings with publishers in the sub-series, "Chronological", and the sub-series, "Chronological (Created)". Correspondence with individuals named in the sub-series, "With Individuals and Organizations", can likewise be found in sub-series "Chronological", and sub-series, "Chronological (Created)".
The correspondence series consists of the following: personal exchanges with individuals, financial matters, commentary on research and publication of Seton writings, greeting cards, invitations and so on, correspondence with scientific institutions, information on lecture tours, institutional and organizational activity (eg. Indian Defense League) and, finally, the Woodcraft League and the Boy Scouts of America.
