- New-York Society for Promoting the Manumission of Slaves (1785-1849), commonly known as the New-York Manumission Society, was established to publicly promote the abolition of slavery and manumission of enslaved people in New York State. While this was the publicly stated goal, numerous members still enslaved people in their own households, including John Jay and Rufus King. The society provided legal and financial assistance to manumitted African Americans in need of protection and enslaved people seeking manumission, and supported legislation and efforts to enforce laws banning the sale of people in New York State. The records include meeting minutes, commission reports, financial records, indentures, and registers from the year of its organization to its dissolution in 1849. Subjects covered include appointments, elections, political activities, finances, reports on individual cases, the sponsorship and operation of the African Free School and African American houses of refuge. Among its active members were: Robert C. Cornell, W.W. Woolsey, Nehemiah Allen, Melancton Smith, William T. Slocum, Samuel Bowne, Adrian Hegeman, Willet Seaman, Thomas Burling, John Jay, Alexander Hamilton, James Duane, John Murray, Jr., William Dunlap, Alexander McDougall, Noah Webster, and Egbert Benson.
- James F. Brown (1793-1868) was the gardener of the Verplanck family at Mount Gulian, Fishkill, New York. Brown had been enslaved in Maryland before running away, and the Verplancks purchased his time after he was found by his enslaver. The collection consists of 8 diaries, 1829-1866, during which time Brown was gardener for the Verplanck family; 1 receipt book, 1832-1857, recording some personal and household expenses, although most entries are unspecified; and 1 memorandum book, 1827-1843. Entries in the diaries are brief, with little elaboration, and pertain to such matters as the weather, local deaths, his gardening activities, the passage of boats on the Hudson, etc. The diaries are not entirely chronological, as in several instances the entries for a year have been copied into a later volume.
- Account book, 1856-1858, kept by the prominent slave trading firm of Bolton, Dickens & Co. of Lexington, Kentucky, with branches in Memphis, Charleston, Natchez, and New Orleans. It chiefly records people purchased and sold by the firm, with entries giving the names of enslaved people, purchase and selling price, profit, names of suppliers, and occasional remarks. Some persons involved in the firm's recorded transactions were Washington Bolton, Isaac Bolton, Samuel Dickens, and the slave trader G.L. Bumpass. Of additional note is a copy of an 1857 letter to Isaac Bolton, probably written by his brother Washington Bolton while Isaac was in prison awaiting trial for the murder of slave dealer James McMillan of Kentucky following a dispute in Memphis concerning McMillan's sale to Bolton of an enslaved 16-year old boy who was later revealed to be free, and other related documents. The volume was later employed as a day book by "B.B.W." (possibly B.B. Wadell) and contains accounts for the year 1865.
