Marianne Haug served as Executive Assistant to the President and Secretary of the President's Council from May 1987 until May 1990. She was employed by various units in the Bank prior to joining the President's office; some of the records in this sub-fonds predate her service in the Executive Office.

Haug's files cover a mix of administrative and program topics. The series of subject files contains a very broad overview of topics that she handled for the President, as well as topics in which she was especially interested, such as the files of the Bank's Outside Interests Committee, 1981-1987, on which she served. The files on environment, forestry, and MIGA are very full; the series also contains copies of speeches by senior members of the Bank, showing that the President's staff was tracking the public statements. Several files, such as Centrally planned economies and Eastern Europe show the Bank's response to the changing situation in Eastern Europe.

The series on budget policy is useful to understand the internal development of budget packages from the point of view of the President's office. Haug's series on the Bank's 1987 reorganization is the fullest in the President's office, covering both the original reorganization and the fine tuning in 1989. Her extensive chronological file dates from July 1985 through May 1991.
