Correspondence from and to Harvey J. Sims, Adam Strohm, Librarian at the Detroit Public Library, and Charles R, Sanderson, Chief Librarian of the Toronto Public Library, between 1927 and 1941, the latter two often enclosing each other's letters. Adam Strohm sometimes encloses letters from Fred Burden, a mutual friend of his and Harvey's. Harvey had initially approached Adam Strohm for advice about books for his library; this correspondence included Sanderson after 1927. As well as corresponding about books these three men developed a friendship demonstrated in their letters, writing about their visits, their travels, and their lives.

Correspondence from Harvey Sims' old friend Fred C. Burden, also a friend of Adam Strohm, from whom there are several letters mixed in this file. Places written from range from Detroit, Michigan, where Fred lived for some time, to California.

Letter from Adam Strohm dated October 21, 1949, Kensington, MD, reporting to Kenneth Sims that Fred Burden had died "two weeks ago" at the age of 86.

Letter from Adam Strohm dated August 4, 1945, Manistee, Michigan to Kenneth Sims. He encloses a letter written to him on July 30, 1945 by Harry Bullock, an old friend of both Adam and Harvey, who says of another friend Fred Burden's troubles from feeling his age: "Harvey Sims passing was part of his trouble and yours and mine too. I think he was the finest Canadian I ever knew."
