Ellen Taaffe Zwilich’s papers were noted as one of the top five acquisitions of 2025 by the Library of Congress Music Division. The library’s blog post below reads in part:
“2025 was another thrilling year of acquisitions for the Music Division. Our top 5 acquisitions were especially staggering in terms of breadth and impact. As always, it is not easy to select only five acquisitions or to even rank them. This year we really built on existing strengths (that is, composers, manuscripts, instruments) while expanding our holdings on notable performers.”
The five noted acquisitions are: a viola made by Antonio Stradivari in 1690; the papers of Stephen Sondheim; the papers of Ellen Taaffe Zwilich; Igor Stravinsky’s holograph working manuscript for the opera “The Nightingale,” 1914; and the papers of pianist Paul Wittgenstein.
