Most of the Subject/Travel series is comprised of files on individual trips made by the Mayor to cities in the U.S. and around the world. These files generally include data on the Mayor's itinerary (with some detail on meetings and other formal functions) and lists of associates accompanying him on the trip. Additional foreign trips are documented in the International Relations Office sub-group; additional domestic travel is documented in various locations, such as the Subject/Speeches series and the Subject/General files on the United States Conference of Mayors and similar organizations.
