Simma Holt's collection is arranged under the main series of personal, publications, and politics. Under the series heading of publications, the papers are organized according to her four books: Terror in the Name of God , Sex and the Teen Age Revolution , The Devil's Butler , and The Other Mrs. Diefenbaker . In addition, there are sub-series for Holt's work as a journalist for the Sun and her work as a lecturer and free-lance columnist.
One of the most important holdings under the sub-series of journalism is a bound volume containing the complete series of The Vancouver Express , the newspaper that began with the lockout of Pacific Press employees on February 21, 1970 and ended when they returned to their jobs on May 15, 1970.
Of the four books published by Holt, Terror in the Name of God is the richest source of documents and photographs. The collection contains letters and records by early Freedomite leaders dating back to the 1920s. Holt went to Ottawa to research Freedomite origins; while there the police gave her access to secret files. Of the photographs, Holt wrote: "So fantastic and bizarre have been the antics of the Sons of Freedom Doukhobors in Canada that photographers have come from across the country and around the world to capture on film the fragments of their strange way of life." The photograph collection contains an album of over five-hundred pictures pertaining to the history of the Doukhobors. In addition, there are approximately 1,000 photos in this collection. These photos were acquired from the RCMP in Nelson B.C., the Vancouver Sun's photographer George Diack, former Nelson freelancer for CBC and the Sun Alice Jane Sloan, and former Nelson News photographer Bob Blackmore. The manuscript collection contains records of Doukhobor trials regarding bombings and burnings in B.C. in 1953, 1958, and 1962.
Holt's tape collection includes many interviews that pertain to The Other Mrs. Diefenbaker . Holt interviewed Edna's relatives as well as many of Diefenbaker's colleagues in parliament such as T.C. Douglas, Paul Martin, and Senator David Walker. She also interviewed Judge Roy Hall about the Atherton case which Diefenbaker successfully defended. Also in the tape collection are telephone conversations of the Satan's Angels motorcycle gang, taped by the police and interviews with Donna, the main character in The Devil's Butler .
In addition to material pertaining to her four books, Holt's collection includes an unpublished manuscript called "Divorce Lawyer," a biography of Neil Fleischman. In the tape collection are eighteen interviews with Hugh Pickett, Canada's best known impresario who became the owner and head of Famous Artists in Vancouver. Holt and Pickett had plans to publish a book using the taped interviews.
Both Terror in the Name of God and The Other Mrs. Diefenbaker evolved through many drafts and revisions. These edited drafts are also in Holt's collection.
During Holt's five year stint in politics, she maintained a voluminous correspondence. Unedited copies of letters written as a member of parliament between July 1974 and June 1979 are also in the collection.
