This impressive compilation offers a nearly complete listing of sound recordings made by American minority artists prior to mid-1942. Organized by national group or language, the seven-volume set cites primary and secondary titles, composers, participating artists, instrumentation, date and place of recording, master and release numbers, and reissues in all formats. Because of its clear arrangements and indexes, it will be a unique and valuable tool for music and ethnic historians, folklorists, and others.
