Another useful resource is the Appendix B of the New Grove Dictionary of Opera , an index of first lines of arias, duets and other ensembles and choruses from opera. It contains title and composer cards for individual vocal works in published collections. The UNC-CH call number of the collection is on each card. Search the onlinecatalog for the song. You can search by composer, first line, title, or poet.
Many translations are available as well.
See the English Translations of Vocal Texts guide in the rack at the Circulation Desk. While some recorded collections are indexed in the online computer, many are not. Check the Carolina blue notebook on the Sound Recordings catalog labeled Vocal Music on Record . This is an in-process index to the Music Library's collection of sound recordings of art songs. If UNC-CH owns the recording, its call number will be written in the book.
