The collection contains business papers such as advertisements, shipping lists, price lists, and invoices from companies in England, Scotland, Ireland, and Canada, dating from 1843 - 1854, many of them fastened into a book. It is uncertain whether they are connected with Brady. His own correspondence is mostly from Felix E. O'Rourke, a drygoods dealer in New York City. Brady's last letters are written from Milledgeville, Georgia where he was engaged in Civil War activities such as sock production, writing Governor Brown about military training, and making recommendations for the staff of the Lunatic Asylum. The business papers of James Creden, Enniskillen, Ireland, are also included.
