Music Library Association.

Founded in 1931, the Music Library Association (MLA) was established to promote the establishment, growth and use of music libraries; to encourage the collection of music and musical literature in libraries; to further studies in music bibliography; and to increase efficiency in music library service and administration. In achieving these goals, the MLA publishes Notes, the MLA's official journal, supports and encourages research in music librarianship, and maintains communication with the music and library communities through their respective professional organizations.
