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 and Halifax, 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. There are 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 there is a manuscript draft of one of his books, Preludes: Sonnets and other Verses (1906).
Item is a manuscript of "In Flanders Fields" by Edith J. Archibald, which sets the words of the poem of the same name by Colonel John McCrae. The piece is for solo voice and piano in F Major and was written at Archibald's home on Inglis Street in Halifax, Nova Scotia. The piece is 5 pages long with extra blank pages.
