Répertoire International de Littérature Musicale (RILM) facilitates and disseminates music research worldwide. It is committed to the comprehensive and accurate representation of music scholarship in all countries and languages, and across all disciplinary and cultural boundaries. RILM is a joint project of the International Association of Music Libraries, Archives, and Documentation Centres (IAML); International Council for Traditional Music (ICTM); and the International Musicological Society (IMS).

RILM’s flagship publication, RILM abstracts of music literature, is a comprehensive international bibliography of writings on music covering publications from the early 19th century to the present.

RILM abstracts of music literature with full text includes the bibliography as well as full-text articles from over 200 journals linked from the bibliographic records.
