9The Stephen Sondheim Encyclopedia is a wonderfully detailed and comprehensive reference devoted to musical theater's most prolific and admired composer and lyricist. Entries cover Sondheim's numerous collaborators-from composers and directors to designers and orchestras-key songs-such as his Academy Award winner "Sooner or Later" (Dick Tracy)-and major works-including Assassins, Company, Follies, Sweeney Todd, and West Side Story. The encyclopedia also contains information about Sondheim's mentoring by Oscar Hammerstein II and his early collaboration with Leonard Bernstein, and profiles the actors who originated roles and sang Sondheim's songs for the first time, including Ethel Merman, Angela Lansbury, Mandy Patinkin, and Bernadette Peters.
