The bulk of the material in the collection relates to McIver's time as a volunteer in the Peace Corps. The majority of items dated between 1961 and 1964 include McIver's correspondence (mostly letters to her mother) her diary, and a scrapbook. McIver's letters and her diary describe her daily activities, thoughts, and concerns regarding the Philipines, the Filipino culture, the Peace Corps, and other volunteers. McIver's scrapbook contains maps of the Philippines, photographs of McIver, the Peace Corps volunteers, Filipino students and citizens. Of note (within the scrapbook) are two signed letters to McIver from President John F. Kennedy and four letters from R. Sargent Shriver, the first director of the Peace Corps, as well as two letters from Congresswoman Martha W. Griffiths (D-Michigan; 1955-1974) commending McIver for her work in the Philippines. The scrapbook also contains newspaper clippings (scattered dates), a 1967 Outstanding Young Women of America certificate, a 1961 Peace Corps Volunteer certificate, and a 1961 Pennsylvania State-Peace Corps Training Completion certificate, among other items.
The collection also includes the Peace Corps 25th and 50th anniversary program announcements and itinerary.
