Gould's papers fall into two series. Family correspondence covers the years 1856 to 1860, when Joseph and his brother Charles were travelling in Europe, and consists of letters home from both young men, and their parents' replies. Manuscript music comprises two volumes of church anthems, with some organ music; some are original compositions by Gould and Samuel Warren. Related to this is Gould's brief manuscript account of the origin of the Mendelssohn Choir. Some family photographs are also included.

Madame Fischer's papers are evenly divided between records of her own career as a performer and material on the Sarah Fischer Concerts. Her performing career is documented by newsclippings, tributes and programmes, reports from the Royal College of Music, and publicity photographs in opera costume. Most of the approximately 50 items of correspondence date from the last five years of her life and concern the disposal of her papers. Taped interviews, in which she discusses her career, include recordings from 1918 and 1925. Material connected with the Sarah Fischer Concerts comprises 143 programmes (1941-1975), press notices, announcements, and a report for 1973-1974. Photographs from this period show Fischer with government and musical celebrities.

The lodge's records consist of a registration book giving the member's name, address, occupation, age, birthplace, wife's name, children between ages of 5 and 15, name of beneficiary, and occasionally remarks on the death of the member of cancellation of membership. Registration books survive from Primrose Lodge No. 49, 1887-1945, Denbigh Lodge No. 96, 1889-1944, Brittanic Lodge No. 113, 1890-1937 and Monarch Lodge No. 182, 1893-1948. Stray items of correspondence from banks or businesses may be found between the leaves of some volumes. The archive also contains two charters from Primrose Lodge, 1887.
