Grove Music Online has recently been incorporated into a new electronic reference product, Oxford Music Online. Oxford Music Online is a portal that provides access to three music reference sources: Grove Music Online, The Oxford Dictionary of Music, and The Oxford Companion to Music. All three resources can be searched at the same time, or you may choose to search only one at a time.
Grove Music Online still contains The New Grove Dictionary of Music and Musicians, 2nd Edition (2001), The New Grove Dictionary of Opera (1992), and The New Grove Dictionary of Jazz, 2nd Edition (2001) and regular updates to those publications. It includes over 50,000 articles from over 6000 contributors from all parts of the world and is the largest English-language music reference source. The migration to Oxford Music Online also includes a few changes to Grove:
The Oxford Dictionary of Music has “content geared toward undergraduates and general users,” while The Oxford Companion to Music, “offers more than 8,000 articles on composers, performers, conductors, individual works, instruments and notation, forms and genres.”
