This revised edition of the standard catalogue of the music and writings of Ralph Vaughan Williams includes all known published and unpublished works, with full details of instrumentation, revisions, and first performances. There is much new information on the location of manuscripts and sketches, and there are many corrections to the information and dates given in the existing text. The volume includes a bibliography of the literary works of Vaughan Williams compiled by Peter Starbuck, and an appendix of folk songs collected by the composer. The indexes have been completely updated.
