Grove Music Online
START HERE!! The New Grove Dictionary of Music and Musicians (29 vols. in print + online) is the premiere resource for academic music research! Contains signed articles on people, places, genres, instruments, etc. Most composer articles have works lists, which serve as indexes to that composer's Collected Works; extensive bibliographies (organized from oldest to newest) are a goldmine which can save you hours of research time.
