Répertoire International de Littérature Musicale (RILM) has created a universe of musical reference resources. It facilitates and disseminates music research worldwide through its comprehensive international bibliography of writings on music, also available in an enhanced version with full-text articles from over 200 journals linked from the bibliographic records, as well as a full-text repository of over 40 seminal music encyclopedias. Tina Frühauf, Associate Executive Editor at RILM, talks about the importance of musical reference works vis-à-vis Wikipedia, technology’s effects on research, and the relativity of currency.
