The files in this series contain Mr. Preston's travel itinerary; briefing books that include background on the country's economy, the Bank's lending program, projects under execution, country profile and map of the country; schedules; meetings with Heads of States and representatives of member countries; minutes of meetings; arrival and departure statements; press statements; and outgoing letters to the government subjects.

The series contains both the files that the President used on the trip and the administrative files created by the President's office, most often by Gisu Mohadjer, an Executive Assistant to Preston, during the preparation for the trips. In some cases, there are Gisu Mohadjer files for a trip as well as files that appear to be the President's copy for use during the trip. Often the Mohadjer file will contain some briefing materials as well as logistical information.

The records include photographs from Mr. Preston's trips to Tanzania, Venezuela, Morocco, and India.
