Her costumes draw special attention, and include several examples on loan from the Metropolitan Opera Archives.

Her pre-war recordings, which show her voice in its freshest brilliance and clarity, include studio recordings of Wagner arias, Beethoven arias, and Grieg songs, as well as duets from Lohengrin, Parsifal, and Tristan und Isolde with Lauritz Melchior. These have been reissued on compact disc by RCA Victor, as well as on Naxos, Preiser and Romophone. Many Metropolitan Opera broadcasts also survive and
