This chronological series contains both incoming and outgoing correspondence transmitted through email, postal mail, or fax. Some handwritten notes between the three co-authors are included. There is no general chronological file between August 1, 1991, and June 30, 1994. Some of the correspondence includes commentary on the history of the Bank, particularly in the chronological file of John Lewis, but the majority of the messages are routine, such as requests for oral interviews and requests for data and documents from Bank offices. Other correspondence consists of comments on drafts, either on draft chapters of the history or on other writings by the authors. Two small files contain a single incoming letter from Sidney Dell (1990) and Peter Wright (1992), each enclosing multiple documents for the authors to use.
