Music to researchers' ears: top ten sites for researching music

Many standard sources for music research, like Grove's Dictionary of Music, International Index of Music Periodicals, and Smithsonian Global Sound, are available only by paid subscription. For casual researchers, or for those who have exhausted these sources, many Web sites orchestrate valuable information and provide musical guidance. This article will highlight 10 sites, all of which are available for free and without user registration. I have evaluated each site for coverage, scope, and ease of use. They should help any researcher of music, as well as librarians who have not formally studied music.
