Series B: Board of Directors File, includes minutes of board meetings (both handwritten and typed), documents submitted to the board for consideration, lists of directors and officers, and some tape recordings of meetings. There are no minutes for the years 1948 to 1951, when NMA was virtually inactive. Only the files for 1969 to 1973 include documents distributed to the board for consideration in addition to the minutes. Tape recordings of meetings cover only 1970-1973.
The executive secretary's notebooks include handwritten minutes of board meetings, annual meetings, and some committee meetings, 1960-1973. Some earlier handwritten minutes, 1952-1960, appear in the volumes of income and expenditures in the Financial Records series (Series F). Typed annual meeting minutes are not included in this series. These appear in the Conventions File (Series D), as does scattered additional material on board meetings held during conventions.
A number of folders of information about the board appear at the beginning of the series, followed by separate chronological sequences of typed board minutes, handwritten secretary's notebooks, and tape recordings.
