The Broadway Musical Cast Album Database. Search by show titles, song titles, singers. Each entry gives year of premiere, year of recording, singer(s), conductor, track labels. Fairly complete through 2007, but it has not been updated for shows premiered, or recordings released, since 2008.
Cast Albums.Org. This database extends and partly duplicates the one above, and focuses on news about new recordings.
Although they may have been superseded by the two databases above, a number of printed discographies of musical recordings, covering Broadway, Film, Television, other staged productions, or a combination, are available in the LIbrary for comparison and further research. Locate these by using the Library of Congress subject heading "Musicals--Discography"
