All of Burke's major biographers have said that he edited Dodsley's Annual Register and wrote its famous Historical Article from 1758 to at least twenty-five years beyond that time. Such statements have been made without the support of an iota of evidence. As a result Burke's share in the Annual Register still remains to be determined. The subject has held the interest of contemporary scholars. Donald Cross Bryant in his account of Burke's literary friendships devotes a separate chapter to the problem. The most recent study of Burke, Thomas A. Copeland's Our Eminent Friend Edmund Burke (New Haven, 1949), contains two such chapters. The matter receives special consideration in Sir Philip Magnus' life of Burke, the latest biography as of today. Burke's other biographers were also interested in his editorship. Macknight observed that “the value ... of the Annual Registers to one who should undertake to write Burke's political history, cannot be exaggerated” (I, XI). Robert Murray says, “It is a valuable source of information on the growth of his thought from 1758 to 1791” (p. 83).
