The Board of Trustees, the Medical Board and the Executive Committee are the major administrative bodies of the Johns Hopkins Hospital. Taken together the minutes of these bodies along with the accompanying supporting papers provide a complete picture of the decision making process at the Johns Hopkins Hospital. Particularly valuable are the supporting papers which not only include copies of many committee reports, but also original letters and documents. For example, the early minutes of the Board of Trustees contain some original letters and memos from Henry Hurd and other members of the medical faculty and staff.
