Book excerpt: The Garden History of Devon is a reference guide to historical sources for over 200 Devon gardens. It also provides an introduction for would-be garden historians on how to conduct garden research. The book is the result of an exploration of the archival resources of Devon's garden history; the objective being to provide signposts to research material for those interested in the development of Devon's gardens. The entries, arranged alphabetically, begin with a brief section describing each garden's history, amplified by quotations from contemporary travellers and diarists; following the descriptive sections are listings of documents, printed sources and illustrations relating to each garden. The greater part of this material is unknown to garden historians.
