The most outstanding English-language music encyclopedia, New Grove Dictionary of Music and Musicians , has recently published its second edition.
Entries reflect all genres of music, including classical, popular, light, world and jazz.
Biographies of composers include complete works-lists. New Grove is searchable not only by article title, but also by keywords embodied within full text articles and bibliographies. Additionally, you can search biographical entries by name as well as by birth or death date and place, nationality, and occupation. Links to carefully selected web sites are also searchable. Alternatively, you can browse articles alphabetically, if you prefer a more standard approach to using the encyclopedia.
