The new Grove dictionary of music and musicians

"This reference classic has approximately doubled in size since its last publication 20 years ago, and the expansion involves more than the thorough revision and addition of articles about music of the past. More articles about 20th-century composers and composer-performers have been added, as well as topical articles about the gender-related, multicultural, and interdisciplinary ways that music is now being studied. Add to these changes that New Grove is also available online, making it a source that would have made its many-faceted creator Sir George Grove proud"--Outstanding reference sources, American Libraries, May 2002.
