This low-cost alternative to two standard reference worksNat Shapiro's Popular Music (Gale, 8 vols.) and Joseph Murells's Million-Selling Records from the 1900s to the 1980s ( LJ 6/1/85)is an excellent buy. Shapiro covers many more songs but is without commentaries. Tyler, like Murrells, provides entertaining thumbnail sketches of each song's history and includes important standards not in Murrells because record sales didn't reach one million. The years covered are 1920-55. Each of the 800-plus songs is entered chronologically/alphabetically under the year it was written or made famous. For each title is listed composer, lyricist, and the performer(s) who had the hit. There is a separate selective biographical section for significant performers and songwriters. The promised indexes to song titles and names were not seen. Highly recommended for circulating and reference music collections. Thomas Jewell, Waltham P.L., Mass.
