Eva Judd O'Meara (1884–1979) was an American music librarian and bibliographer.
O’Meara headed the Music Library at Yale University from its inception in 1917 until her retirement in 1952.
"[3] The Eva Judd O'Meara Award, first given in 1979, was established by the MLA to recognize the best review in Notes.
[4] A few weeks before her death in 1979, she spoke to a conference of music librarians at a meeting of the New England Music Library Association.
At this meeting she recalled a story of how she acquired the Music Library's most prized possession, the Clavier-Büchlein vor Wilhelm Friedemann Bach (1720), a book-length manuscript that Johann Sebastian Bach wrote for the education of his ten-year-old son.
