The Papers are organized into ten series:

1. Correspondence 2. Photographs 3. American Red Cross 4. Newspapers and Newsletters 5. Journals 6. Notebooks 7. Manuscripts 8. Artifacts 9. Books 10. Collection History

The first series, Correspondence (1927-1970), contains the bulk of the collection, and captures Suzanne Macpherson's World War II experience. The series is arranged into two sub-series: Suzanne Macpherson and Others. The Suzanne Macpherson sub-series is further organized to identify items sent to Suzanne Macpherson and those sent from her. The Other sub-series contains correspondence that does not involve Suzanne as a sender or receiver. The authors include her friend and fellow Clubmobile girl, Lydia Sherwood, her fater, Charles Rust Macpherson, and military and American Red Cross officials. Of note are the numerous v-mail, short for "Victory Mail," documents that arose during World War II as a secure method to correspond with soldiers and service workers abroad. Within each sub-series, the letters are organized alphabetically by last name of the sender and arranged chronologically by date.

The Photographs series (1943-1967), contains images of World War II, and of Suzanne's travels in Europe and North Africa after the war. The series is arranged by content, including images of European landscapes with and without subjects, photographs of soldiers, and clubmobile girls. The series also contains one photo album with photos from a trip to North Africa in January 1961. There is also a sub-series arranged into two files of dated and undated photos of Suzanne Macpherson.

The third series, American Red Cross (1941-1945), contains material regarding Suzanne Macpherson's World War II service, including her immunization records and general information about the American Red Cross organization, and pamphlets and artifacts Suzanne Macpherson collected as an American Red Cross Clubmobile Girl.

The Periodicals series (1915-1965) includes publications from G.I. Divisions, the American Red Cross, and established newsoutlets, like "The New York Times," that document World War II. Of note is the file, "Clippings," which contains newspaper clippings about Suzanne Macpherson and other donut girls. It is organized by publisher, with the bulk of the material in the military newspaper, "The Stars and Stripes: Mediterranean."

The fifth series contains the journals (1935-1944) Suzanne Macpherson kept throughout her life. Three journals capture her time traveling in Germany prior to the war in 1935 and her time with the American Red Cross. One journal is from 1943, and it documents her activities in North Africa, while the other spans 1942-1944 and contains entries concerning her day-to-day Clubmobile experience.

The sixth series, Notebooks (1936-1967), contain 14 notebooks that are organized into three chronological sub-series: 1940s, 1960s, and undated. The 1940s documents Suzanne Macpherson's day-to-day activities during her time at war, including what she did that day, names, and addresses of people she met. The notebooks from the 1960s contain similar information, but are from after the war. The series also includes fellow Clubmobile girl, Lydia Sherwood's notebook in the 1940s series, and notes of Suzanne Macpherson's about the Clubmobile Girl position prior to going abroad.

Manuscripts (1937-1971) are organized into four sub-series, arranged alphabetically: Education, Plays, Poems, and Short Stories. The Education sub-series is arranged chronologically, and contains documents that Suzanne Macpherson wrote about the state of education. On Education also includes students' graded papers. Plays written by Suzanne Macpherson are arranged alphabetically in three files, and one sub-series, Script, is organized chronologically. Poems written by Suzanne Macpherson are arranged chronologically, and there is also a sub-series of Non-Original Work. Short Stories are organized alphabetically with two files and one sub-series, arranged chronologically. Many of the short stories are written about the war experience.

The Artifacts series contain items in the collection that Suzanne Macpherson accumulated through her travels after World War II. It includes three spoons from Venice and Rome, and currency from Yugoslavia and other various countries, and illustrations and maps and itineraries from a trip to North Africa.

The ninth series consists of nine books that were gifted to or collected by Suzanne Macpherson. The books are arranged alphabetically by title.

It contains her diplomas from Pierce College and Stanford University, and a Yale Honor Award. Suzanne Macpherson's estate files contain documentation regarding the donation of her papers to Scripps College.
