Fonds contains music manuscripts and published scores, photographs, and autograph letters written by well-known composers such as Jacques Offenbach, Giuseppe Verdi, and John Philip Sousa.
Through his work as a music critic and journalist in Toronto, Ontario and Halifax, Nova Scotia, Logan communicated with many prominent Canadian musicians in the early twentieth century. Many of the scores, photographs, and autographs included in this collection are a result of his contributions to music criticism. The music and theatre programs are frequently annotated with comments for reviews, and most of his correspondence with musicians and actors relates to his work as a music and theatre critic. Some of the scores were given to Logan as gifts from performers while others were sent to him for review or publication in newspapers. The fonds includes several manuscripts of songs by Edith Jessie Archibald, a prominent social activist and suffragist in Halifax.
Letters sent to Logan also concern his poetic contributions, and the manuscript of one of his books, "Preludes: Sonnets and other Verses," (1906) is part of the fonds.
