This collection consists of a plantation account book kept by Josephus Brooks while serving as overseer of Franklin Boliver Sublett's plantation in Trinity County, Texas, documenting agricultural operations, weather, travel, and the lives of enslaved people from 1859 to 1861, along with a later farm record from 1873-1874. Also included are biographical and genealogical materials relating to Brooks and Sublett.

This collection consists of store accounts, receipts, drug store orders, several notes and leters, a stock certificate, and some matchbooks. Researchers might find the receipts in Folder 1 useful for identifying early 20th-century Nacogdoches businesses. The letter in Folder 9 about a slave named Jim trying to buy the freedom of himself and his family is also of research interest.
