To find scores and recordings for voice, you can either search the catalogue (see the sections on Scores and Sound recordings) or browse by call number.
For vocal scores, see M10 for mixed orchestral and vocal, and M15 - M23 for opera and concert arias, songs and leider, and song collections. For technical manuals, also see the section on singing and vocal technique (MT820 - MT915).
