The collection has been divided into six series: General and Business Correspondence; Political Correspondence; Private and Family Correspondence; Land Records; Photographs, and Bound Volumes.

General and Business Correspondence is the first and largest series, comprising the first 190 record cartons. Very little re-arrangement has occurred in this series and the material is in basically the same order in which it was received. It is arranged rather eccentrically: some of the correspondence is arranged alphabetically and some chronologically, but most of the folders have specific titles or specific subjects. The alphabetical section is generally arranged according to the individual correspondent's last name, although in some cases a company name is used instead. In addition to manuscripts, the series contains business documents such as cancelled checks and vouchers. The voucher files contain a variety of material, including correspondence, invoices, and checks.

Political Correspondence and Private and Family Correspondence, the second and third series, have been physically relocated to follow the first series. This was done because there were several discrete manuscript boxes for each of these series, and so it was easy to move the entire contents of the boxes in their original order. Political Correspondence comprises box 191 and box 192 folders 1-26. Private and Family Correspondence is located in box 192 folders 27-53, box 193, and box 194 folders 1-9. However, the researcher needs to be aware that there are folders labeled political correspondence and private correspondence throughout the collection that have not been incorporated into the series. Those known to the processor are in boxes 27, 28, 41, 50, 60-63, 68, 69, 82, 84, 92, 100, 114, and139. Boxes that may contain private or family correspondence include 54, 56, 63, 82, and 139.

Land Records, the fourth series, is comprised mainly of deeds and abstracts, with a few miscellaneous legal records such as indentures and probate records. None of the material in this series had been processed at the time the collection was received. It has been refoldered, but remains in the original order in which it was received. Land Records are found in box 194 folders 10-34 and boxes 195-201.

The fifth series, Photographs, contains eighty-one photographs, thirty-six of which are housed in three oversized boxes. The photographs are arranged by date; if undated, they are arranged in rough alphabetical order. They are in box 202.

The last series, Bound Volumes, contains 356 bound volumes divided into nine sub-series: Checkbooks; Corporate; Financial; Land; Legal; Letter books; Letter Books, Fragile; Railroad; and Shorthand/Stenographic Notebooks. Each volume has been numbered sequentially; material within each sub-series has been arranged alphabetically except the Letter Books sub-series, which have been arranged chronologically. Loose material found inside several of the bound volumes has been foldered and placed in box 190 folders 19-27. Fragile letter books, numbers 195-204, have been placed in record cartons.
