From the Sugar Act of 1764 through the Tea Act of 1773, the British Parliament imposed a variety of taxes upon their American colonies in an effort to raise revenue to offset the enormous debts incurred during the Seven Years' (French and Indian) War. Far more efficiently than raising revenue, these duties raised the indignation of the colonits, contributing more than their share to the alienation that fueled the independence movement The two volumes that comprise the Pennsylvania Stamp Act and Non-Importation Resolutions Collection contain 34 manuscript and printed items relating to the political crisis over taxation on goods imported into the American colonies between 1765 and 1773, with a focus on Philadelphia. The first volume is concerned exclusively with agitation over the Stamp Act of 1765 and its repeal, while the second volume relates more specifically to the Non-Importation agreements of the 1760s, the Townshend Duties, and the Tea Act of 1773. Among these are letters of Governor John Penn, correspondence between the Sons of Liberty at Philadelphia and those of New York, 1766, an address of the committee of Boston merchants to a committee of Philadelphia merchants, 11 August 1768. Among the more dramatic letters are those from John Hughes, the would-be Stamp Officer for Pennsylvania who resigned bis commission in the face of public protest, and a seies of threatening letters addressed to James and Drinker, consignees for the sale of tea in Pennsylvania in 1773.

One of the oldest houses in Philadelphia, Wyck is now a non-profit museum listed on the National Register of Historic Places. Nine generations of the Jansen-Wistar-Haines family owned the Wyck property from 1690 until 1973. The last family owner deeded 2.5 acres of land, the house and its contents, several outbuildings, a landscaped garden, and a small endowment to the Wyck Charitable Trust. The Wyck Charitable Trust and the Wyck Association now administer the preservation of the property and its educational services to the public. This collection contains diaries, letters, accounts, bills and receipts, deeds, and photographs. The collection as a whole is deepest for the period 1770-1970. Items of particular note include accounts of household expenses at Wyck from ca. 1790-1970; papers pertaining to the Academy of Natural Sciences of Philadelphia, Quaker schools, and social reform groups; agricultural and horticultural practices; and correspondence to and from cultural leaders of 18th and 19th century Philadelphia. The papers of the John S. Haines family (Ms. Coll. 52A) form part of the Wyck Papers. The papers cover the years 1845 to 1949 and are arranged into eight series.
