The Historical Society of Pennsylvania has in its files many collections of manuscripts, a great number of which pertain to the business records of Philadelphia merchants and institutions, both commercial and municipal. The collections are as varied in content as they are in size and in periods covered. Any student of Pennsylvania industrial, commercial, or financial history, from the earliest days of the colony to the more familiar recent years, will find many contemporaneous records to assist him.
