original passage: During the year following that contract, Burke founded with Dodsley the influential "Annual Register", a publication in which various authors evaluated the international political events of the previous year. The extent to which Burke contributed to the "Annual Register" is unclear. In his biography of Burke, Robert Murray quotes the "Register" as evidence of Burke's opinions, yet Philip Magnus in his biography does not cite it directly as a reference. Burke remained the chief editor of the publication until at least 1789 and there is no evidence that any other writer contributed to it before 1766.
original sentence: The extent to which Burke contributed to the "Annual Register" is unclear.
