- Production music libraries license their copyrighted music for use in film, television and radio productions.
- Performance libraries serve performing music groups, particularly large orchestras, by acquiring, preparing, and maintaining music for performance.
- Digital music libraries and archives preserve recordings and digitized scores or literature in a variety of electronic formats. Many music libraries dedicate part of their duties to digitizing parts of their collection and maintaining digital files. Digital preservation requires specific procedures to avoid decay, obsolescence, and loss. Digital materials may be part of a larger, physical collection, or may compose an entirely electronic collection not physically accessible (usually housed on a network or on the Internet). Access may be limited as a fee-based service, a private service to specific user groups (such as students at a conservatory), or freely accessible to the public.
