Vally Weigl donated the bulk of Weigl’s holograph scores and sketches, as well as copyists’ and published scores, to the New York Public Library. Scattered additional holograph compositional material is held at the Library of Congress, the Austrian National Library, and the Wienbibliothek im Rathaus. These archives, and other research libraries and institutions listed below, also hold primary biographical material (correspondence, photographs, and papers), ancillary performance documentation (programs and reviews), and secondary literature; the Karl Weigl Papers at Yale University, in particular, include a wide range of such life documents. All research institutions allow materials to be viewed and studied on site only. For information on a specific work, click on Music on the navigation bar or search this site by title.
