Much of the material relating to the history of the history of the congregations before 1933 was destroyed in a fire. Most of the surviving records date from 1949 and were found in 1990 in the balcony of the synagogue. Extensive records of correspondence, annual reports, minutes, financial records, and membership lists were among what was found. There is also a large section of information available on bat/bat mitzvah, marriage and burial records for the genealogist. The cemetery records are the most complete as a database of all burials in the Shaarei Zedek Cemetery was compiled between 1997 and 2011. Material on these lifecycle events generally comes from personal memorabilia and newspaper records. A section on Jewish traditions and holidays is appended to show how these have been observed in this community and elsewhere.

Records for the communities in Moncton and Fredericton are very limited and include information found in public records including newspapers.

The fonds consists of 9 volumes of minute books. The 5 volumes dated from 1897 to 1945 belonged to the United Women's Missionary Societies and the remaining 4 volumes (1945-1973) belonged to the Women's Inter-Church Council of Saint John.

Information about the structure of meetings, some names of members and missionaries and general missionary work is included. The Women's Inter-Church Council minutes include some financial reports, a type copy of the constitution and by-laws adopted in 1967, and some printed orders of church services and newsclippings relating to the annual World Day of Prayer. In volume 9, there are lists of executive members and denominational members of the Council from 1965-1973.

The fonds consists of a record book for Zion Church, dated 1859 to 1865. The record book contains the minutes of monthly church meetings that include some names of those present. It documents the structure of the meetings and type of business conducted. An historical sketch of Zion Church, its endowments, rules of order and a confession of faith, are included in the book. There is also a membership list for August 1864 with names and street addresses.
