abstract: This document is a compendium of the materials that are housed within the special collections donated by Thomas Everett. In August 2016, the Arizona State University School of Music, through the efforts of retired Professor of Trombone Douglas Yeo, received a donation of materials from Thomas Everett, founder of the International Trombone Association and retired director of bands at Harvard University. This donation contains published and unpublished music, numerous letters, and various drafts of his book, An Annotated Guide to Bass Trombone Literature. Over the course of two-and-a-half years, the donation was catalogued for the university by the author. Materials from the donation were sent into public circulation or sent into special collections within the ASU School of Music Library. / Dissertation/Thesis / Doctoral Dissertation Music 2019
