The Montreal Mendelssohn Choir Collection comprises several volumes of sheet music from the Choir’s library. The choral folios were compiled and bound into eight volumes at the time of their donation to McGill University in 1895. The estate of D. Torrance Fraser, a former Choir member, donated another four volumes of choral music in 1926 and 1927. Three volumes contain second copies of the pieces from the Choir’s library donated thirty years prior; the fourth volume donated in 1927 contains a number of pieces performed by the Choir but not found in the seven extant volumes from the Choir’s library.
