This volume contains letters (a few in shorthand) relating to his pursuit of the position as principal recorder, and then, upon accomplishing this, his problems in publishing. There are sales accounts and a diary (April, 1793 to June, 1794), written while he was imprisoned in Newgate Prison, London (1793 to Jan., 1796). Included for this period is an interesting description, brought to him at Newgate by an Englishman, John Ford, who was seeking support and American contacts for his plan to take an English textile process to America: "A Manufacture of Wollen & Cotton Cloth & Without spinning or weaving," August, 1794.

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.
