Letters and manuscripts of MacDowell. One group was written to Arthur P. Schmidt, his publisher during MacDowell's years as professor of music at Columbia University. These letters concern the publication and distribution of his compositions and his copyright difficulties with other firms, especially Brietkopf & Härtel. There are eight letters from MacDowell to the American pianist, composer, and pedagogue William Mason. This personal correspondence deals with such things as musical pieces dedicated by each man to the other. A diary and letter book belonging to Marian N. MacDowell (Mrs. Edward) contains draft copies of letters to Nicholas M. Butler and others relating to his controversial career at Columbia University. Also, photocopies of eight letters from the Mary Flagler Cary Music Collection at the Morgan Library. Among the numerous musical scores and sketches are his INDIAN SUITE and the SONATA TRAGICA.

Manuscript notes of and some related letters to Knowles relating to his research on a 16th century English manuscript, ANATOMIE OF SPAYNE, 1599.

There are photostatic copies of the manuscript as well as photostatic copies of related manuscripts and printed items used by Knowles in the course of his research. Also, a typescript of the English text with annotations by Knowles. The research appears to be incomplete since the letter file ends in 1967, the year of Knowles' death.
