First published in 2011, this text provides citations to the core Holst literature. The volume is intended for students and researchers, as well as those seeking an introduction to Holst. The inclusion of materials for the non- specialist seems entirely appropriate as Holst devoted much of his career to teaching amateur musicians. The contents of this book presents a selective, annotated list of essential materials published through the end of 2009, although a very few exceptions were made for a limited number of post-2009 print and web resources.
