The correspondence series includes miscellaneous correspondence arranged chronologically and files of correspondence arranged alphabetically by individual correspondent. Copies of Gersovitz's own letters are scattered throughout the files.
The miscellaneous files include letters from students, congratulations on exhibitions and letters of appreciation from collectors. Among the miscellaneous correspondence are a letter from Alex Tilley, 1974, of Tilley hat fame, relating to his attempts to establish a business as an art dealer, and a letter from printmaker Fran Jones (Rosewarne) relating to the destruction by fire of Gallery 1640 in 1971.
The individual files include extensive correspondence from the owner of Gallery 1640, Estelle Hecht, dating from 1958, before she established the gallery, until her death in the gallery fire in 1971. Estelle Hecht was a personal friend of Gersovitz's and wrote newsy letters to her when she was out of town during summer holidays. The Hecht letters document her struggles as an artist and art dealer, exhibitions at the gallery, Gersovitz's work, and other artists' careers. There is also extensive correspondence with Colin Graham, former director of the Art Gallery of Greater Victoria, documenting Gersovitz's exhibition at the gallery in 1966 and the friendship that formed and led to a continuing correspondence up to the present, discussing Gersovitz's career as an artist and playwright, Graham's own painting, and Canadian art in general. There is also correspondence with A.S.H. Mills, the secretary of the Royal Society of Painter-Etchers and Engravers, 1957-1965, documenting Gersovitz exhibiting with the society and Mills' sympathetic criticism of her work. Other significant correspondents are the German printmaker Herman Clemens, who arranged an exhibition of Gersovitz's work in Germany and for whom, in turn, she arranged an exhibition in Canada, and Joe Sherman, editor of "ArtsAtlantic", relating to Gersovitz's reviews for the journal, their editorial relationship, her art and his writing, and to the arts in Montreal and the Maritimes in general.
Additional material received in 2006 include personal correspondence from friends, including silversmith Lois Betteridge, Aura Cuevas and Ann and Joe Sherman, prior to his death in 2005.
