The largest part of the Gibson Papers consists of papers of Archbishop Tenison, and includes some concerning his Cambridge career and his tenure of the see of Lincoln. The rest of the collection consists of papers from four distinct sources. These are:
(1) Bacon. A quantity of papers are strays from the papers of Anthony Bacon, secretary to Robert Devereux, 2nd Earl of Essex, whose papers are now MSS. 647-62. A complete volume of the papers of Francis Bacon (MS. 936) probably has a common origin with the Anthony Bacon papers.
(2) Murray. A quantity of papers concerning the reign of James I, many of them relating to events in the Palatinate, appear to be strays from the papers of Thomas Murray (1564-1623), secretary to Charles I as Prince of Wales and Provost of Eton in 1622, which have recently been identified as MSS. 663-9.
(3) Lambeth. A number of papers probably emanated from Lambeth, though their exact origin is not at present always certain. Amongst them are sixteenth-century documents concerning the Family of Love, and various documents relating to Tenison's predecessors Archbishops Whitgift, Laud, and Tillotson.
(4) Gibson. A small number of papers seem to have belonged to Gibson himself and concern the early part of his career.
