This series documents the work IVS oversaw in developing countries around the world. Most of this series consists of reports written by volunteers, field directors, regional directors, and other IVS personnel. The project files were pieced together from a number of different types of files -- alumni files, report files, field director files, etc. -- and therefore are not consistently arranged or described. The earliest reports are filed chronologically. Later materials are organized alphabetically by name of country or region. Under each country or region name, researchers will find materials ordered roughly by date, project name / region, or volunteer last name.
