This series contains records of President Clausen's visits abroad and his appearances and presentations in the United States. The files contain travel itineraries, briefing materials, arrival and departure statements, press conference briefings, remarks, schedules of meetings and appointments, correspondence (letters, memoranda, telexes and facsimiles written to and from government leaders, thank you notes), lists of government officials and biographical data about them, general background information on countries and governments, status reports on projects in execution, maps and newspaper clippings. The file on Niger contains photographs of the ministers. Some files listed under a country are primarily files on a meeting held there, not on the country per se; see, for example, the GATT meeting file under Switzerland. Itineraries and briefings for Mrs. Clausen when she accompanied the President on foreign visits are found in some files. The general files at the beginning of the series contain travel orders and itineraries but no background information.

The series is rich in annotations and comments by Clausen and his advisors. It provides snapshot views of the countries at the time of the visits and also provides particularly useful information on the World Bank's relationship with each country.
