Collection of 92 pieces of sheet music, chiefly from the United States, most with title page illustrations.

Thirty-five titles of sheet music related to the 1901 Pan-American Exposition in Buffalo and one title related to an exposition held in 1905 in Buffalo. All but nine of the titles are photocopies of works in the Buffalo & Erie County Public Library.

The collection contains approximately 1300 scores, half of which bear markings entered by Mikhashoff or his colleagues in preparation for performance. The collection includes manuscripts and print publications, both originals and reproductions.
