Much of the material in both volumes is printed in Charter to William Penn, and Laws of the Province of Pennsylvania . . . (Harrisburg, 1879). The first volume, prepared possibly for James Logan, contains copies of Charles II's grant to William Penn of the Lower Counties, 1683, an act of the Privy Council, 1705, the charter of Pennsylvania of 1701, acts of the Assembly, 1682-1719.

Three volumes contain letters, laws, charters, reports, proclamations, petitions, and other official and semi-official documents relating principally to early Pennsylvania and New Jersey, signed by or addressed to William Penn, among others. A fourth volume is Penn's cash book, 1699-1703, which records expeditures, payments of quit rents, etc. Tipped in is "Catalogue of Goods left at Pensbury," and of goods left at Philadelphia, 1701.
