Frederick Delius is among the most celebrated English composers of the twentieth century. Widely studied and performed, his works are considered models of the British impressionist school and continue to fascinate students and scholars centuries later. But there is no currently available annotated bibliography to his life and work. The body of the book will be increased from 1500 to 2000 entries, with particular emphasis on the last decade's explosion of book-length works on Delius and his music. The goal will be to produce a guide that serves as a ready reference for students and scholars, but will also be interesting to read and useful for anyone who wants to know where to begin to learn more about this important composer.
